Sig Sauer says it has been able to trim the weight of the Army’s new 6.8x51mm M7 service rifle by nearly a pound, or just over 10 percent, in response to feedback from servicemembers. The M7’s weight compared to the gun it is set to replace, the 5.56x45mm M4A1, was among the criticisms that an Army captain very publicly leveled against the gun earlier this year. Sig had subsequently issued a vehement rebuttal, but acknowledged that the design was still evolving.

Jason St. John, senior director of strategic products for the Defense Strategies Group at Sig Sauer, gave an update on the M7 rifle, as well as the companion 6.8x51mm M250 machine gun, to TWZ‘s Howard Altman on the show floor at the Association of the U.S. Army’s (AUSA) main annual symposium today. Sig Sauer has also been working on a shorter and lighter carbine variation of the M7 for the Army. Sig Sauer did show the lightened “product-improved” M7, also known as the PIE M7, at the biennial Defense and Security Equipment International (DSEI) exhibition in London earlier this year, but does not appear to have had the carbine on display at that event.

The M7 and M250 (previously designated the XM7 and XM250), together with the associated family of 6.8x51mm rounds and the computerized XM157 optic, form the Army’s Next Generation Squad Weapons (NGSW) ‘system.’ The service selected Sig Sauer as the winner of its NGSW competition in 2022 and now plans to replace a substantial portion of its M4A1s and M249 Squad Automatic Weapons (SAW) with M7s and M250s, respectively. Sig is also supplying the ammunition, but the XM157s are being procured separately from Vortex Optics.

“So, we’re talking about the Army’s and our continued teaming effort to improve the M7 and the M250, based on our recommendations, and their suggestions, and feedback from the field,” Sig Sauer’s St. John said.

“There’s basically two combined efforts going on within the M7,” he continued. “We have a carbine version, and then we have a lighten, improved version of the M7. And so when you look at the standard M7 that’s been issued to the troops, the overall weight of the firearm was 8.3 pounds. Now, the improved M7 is 7.6 pounds, and the carbine version weighs 7.3 pounds. So we’re getting closer and closer to [a] rifle weight system similar to the M4.”

The PIE M7 also has a 13.5-inch barrel, while the one on the carbine version is 10 inches long. A standard M4A1 with its 14.5-inch barrel, as well as just a sling and a loaded magazine, weighs in at 7.62 pounds, according to the Army. It is important to note that optics and other accessories add appreciable weight to both the M7 and M4A1. The XM157 optic is notably larger and heavier than the ones the Army typically issues for use on M4A1s.

In terms of how the PIE M7 was lightened, “there’s the upper receiver, we’ve redesigned and taken some weight out of it. We’ve lessened the barrel profile slightly to get some weight out of it,” according to Sig’s St. John. “We’ve done some lightening efforts within the operating system, as well as remove the folding stock hinge. By removing that hinge, we save some weight.”

The original M7 featured a stock that was both adjustable in length and could be folded to one side. The M4A1’s stock is only adjustable in length.

“What we just found is really that the Army and the soldiers have fed back … [that] they’d rather have the weight savings than the folding stock,” St. John added. “They aren’t using the folding stock enough to justify that additional weight.”

The video in the Tweet below shows a placard with additional details about the PIE M7 and the carbine version at around 0:41 in the runtime.

Sig Sauer has also made important changes to the M250’s design based on discussions with the Army and feedback from soldiers.

“You’re going to see, instead of having a removable front handguard, now you have a hinged captured handguard, so it stays on the weapon system – rotates forward and away,” St. John explained. “The feed tray cover is extended with the big rail, so that now I have more adjustability for the optics that I put on there, and eye relief to the individual soldiers, and now I can move my optic further back or forward depending on what’s wanted.”

“I’ve got improved bipods. I’ve got [an] improved gas valve,” he continued, also highlighting improvements to how the M250 can be fitted to a tripod and how ammunition is carried on the gun. “Basically the feedback from everyone is, what can we do to improve this weapon system, make it more easy [sic] to use, and more robust and reliable.”

Work has also been done to improve the common sound suppressor for the M7 and M250.

“We’ve also redesigned our suppressor to make it shorter,” per St. John. “We’ve added a titanium heat shield on it that does two-fold [things].”

The heat shield helps reduce the chance of contact burns as the suppressor heats up during use. It also reduces thermal bloom, which could make it easier for enemies to spot friendly forces from their heat signature. St. John cautioned that no one should be rushing to grab the suppressor, especially with bare hands, after sustained use, even with the new heat shield.

When it comes to the M7, St. John said that the Army is now in the process of deciding how to proceed in fielding the PIE and/or carbine versions.

“You could see there’s probably a couple of decision points. Do they stick with the standard length M7 that’s been lightened by 0.7 pounds? Or do they and or do they move to the carbine completely?” he said. “Do they keep the carbine for specialty troops and still issue the M7, or do they take the carbine and utilize that as the new rifle across the board? So they’re trying to make those decisions.”

St. John pointed out that the Army had gone through a similar evolution in thinking in the decades that followed the fielding of the A1 variant of the M16 in the 1960s. The service adopted a succession of full-size rifle versions before transitioning to the shorter and lighter M4A1 as its standard service weapon.

That the Army is looking at lighter variations of the M7 at all is significant. The weight of the rifle was among the criticisms that Army Capt. Braden Trent had highlighted in an unclassified report he wrote while he was a student at the Expeditionary Warfare School, which is part of the Marine Corps University in Quantico, Virginia. Trent also called attention to the comparative size and weight of the 5.56x45mm and 6.8x51mm rounds, as well as the shorter barrel on the M7 compared to the M4A1. Trent’s findings, which raised safety concerns about the rifle and cited other issues that called its operational utility into question, came to more widespread attention after he presented them at the annual Modern Day Marine conference earlier this year.

There is one particular “major fault in the XM7, and that’s the UBL … or universal basic load. It’s a metric that can be applied to almost any weapon system, and it essentially means the amount of magazines and associated ammunition that a system uses and is expected to be carried into battle,” Trent said at Modern Day Marine. “So the XM7 [and] the M4A1 actually have the same number of magazines in their UBL seven, but remember, we’re talking about that capacity difference. The total round count a soldier carries into battle with the XM7 is 140 rounds compared to the 210 rounds of the M4A1. Now again, a 70-round difference may not seem significant, but to the soldier in the fight, it absolutely is a difference. Not to mention that every magazine added to the XM7, each 20-round loaded magazine adds another 1.25 pounds to the soldier’s load, meaning that if troops equipped with the XM7 tried to match their old UBLs [in terms of round count], they’re going to have even more weight being carried.”

“The final thing I’d like to mention is the Chief of Army Infantry’s stated goal of a 55-pound total soldier load,” he added. “If we just take the XM7 and its seven UBL magazine load, we’re almost at half that weight, and that’s before the soldier is put on body armor, water, a rucksack, or anything else that they’ll need in the fight.”

The Army’s position has been that the M7 and its new cartridge offer improved accuracy, range, and terminal effectiveness that are worth the added bulk. Concerns about soldiers being outranged, as well as improvements in adversary body armor, were key drivers behind the NGSW program. Trent’s report also calls this into question based on data he collected regarding expected infantry combat engagement distances.

Sig Sauer had also provided a lengthy rebuttal to the technical issues that Trent raised. You can read more about all of this in TWZ‘s in-depth report on the ensuing controversy following his presentation.

“I think that soldiers and citizens should want Sig Sauer, the U.S. [Army] program office to continue that practice of continually evolving and developing and improving their soldiers’ weapons systems. And I think we anticipate that we’re going to undergo those improvement processes for the next 25 to 30 years,” the company’s St. John had told TWZ at the time. “There’s going to be improvements in manufacturing [and] materials processes. The soldiers on the ground and the U.S. Army are going to dictate different operational requirements and standards for the weapons systems, and we’re going to have to react to those modifications that are going to optimize that weapon system as that evolves through time and history.”

“It should be no surprise, in my opinion, that specifically in the infancy of a weapons program that there’s a very aggressive improvement effort to ensure that the Army and the soldiers get the weapon system that they deserve,” he added.

From what we know now, the Army’s plans for the M7 are already evolving significantly, with criticisms about the rifle’s weight, in particular, having been taken to heart.

The American subsidiary of Belgian gunmaker Fabrique Nationale (FN) has delivered new prototype rifles and machine guns chambered to fire the 6.5x43mm Lightweight Intermediate Caliber Cartridge (LICC) to the U.S. military. LICC is one of several avenues the U.S. military has pursued in the past decade to find new small arms that offer greater range and terminal effectiveness, particularly over existing types firing the 5.56x45mm round. Though a U.S.-led effort, Canada has also been deeply involved in LICC.

FN America put out a press release today saying it had provided an unspecified number of test samples of the LICC-Individual Weapon System (LICC-IWS) and LICC-Assault Machine Gun (LICC-AMG) to the Irregular Warfare Technical Support Directorate (IWTSD). The IWTSD, first established in 1999 as the Combating Terrorism Technical Support Office (CTTSO), resides within the Office of the Assistant Secretary of Defense for Special Operations and Low-Intensity Conflict. It is charged with identifying and developing new capabilities primarily to aid in irregular warfare operations. In U.S. military parlance, irregular warfare is an umbrella term that encompasses a host of lower-intensity mission sets, including counter-insurgency and counter-terrorism, as well as advising and assisting foreign forces, often performed by special operations units.

The LICC effort traces its roots back to the mid-2010s. The 6.5x43mm cartridge evolved directly from the .264 USA round, which was developed internally by the U.S. Army Marksmanship Unit (AMU). FN has been under contract to develop a weapon system to go with the LICC ammunition since 2019. The steel-cased 6.5x43mm rounds are 20 percent lighter than equivalent cartridges with brass cases, and have better accuracy, range, and performance compared to typical 5.56x45mm loadings, according to the company.

The LICC-IWS is a version of FN’s Improved Performance Carbine (IPC). Though it has some broad external resemblances to the AR-15/M16 family, as well as larger AR-10-style guns, the IPC is a proprietary gas-piston operated design that first broke cover in 2023.

FN America has developed three subvariants of the LICC-IWS with 12.5-inch, 14.5-inch, and 18-inch barrels, referred to as the Close Quarters Battle, Carbine, and Designated Marksmanship Rifle types, respectively. The company says the 14.5-inch barrelled version is 35 and a half inches overall (32 and a half inches with its stock collapsed) and weighs 7.75 pounds. This puts it in the same general size and weight class as the 5.56x45mm M4A1 carbine, which continues to be widely issued across the U.S. military and has been something of a control standard for the LICC effort.

“Initial test firing results from the U.S. Army Marksmanship Unit and other operators show that the accuracy of the LICC-IWS is consistently two times better than the M4A1,” Jim Williams, Vice President of Military Programs for FN America, said in a statement today. “Additionally, the LICC-IWS handles like the M4A1, yet remains soft shooting when firing the new 6.5×43 lightweight ammunition.”

The LICC-AMG is a 6.5x43mm variant of FN’s Evolys machine gun, which made its public debut in 2021. The belt-fed Evolys is also offered chambered in 5.56x45mm and 7.62x51mm. The LICC version has a 14.5-inch barrel, is nearly 40 inches long overall (36 and a half inches with its stock collapsed), and weighs nearly 14 pounds. FN America says it has tested the LICC-AMG against its Mk 48, Mk 46, and M249 Squad Automatic Weapon (SAW) machine guns. The Mk 48 is a 7.62x51mm derivative of the 5.56x45mm M249. The Mk 46 is a special-purpose subvariant of the M249. All three types are in service with various elements of the U.S. military.

“In prototype testing, the AMG was more accurate than the FN MK 48 in full auto mode,” according to FN America’s release today. “Overall, the AMG demonstrated improved performance in lethality, accuracy, durability, balance, and handling over the FN M249 and FN MK 46/MK 48 machine guns.”

“FN’s ultimate goal is to advance from development into production and field a final solution that provides operators a system that is easier to operate, more accurate and more effective than anything available today,” Mark Cherpes, President and CEO for FN America, also said in a statement. “After this test and evaluation phase, our plan is to take user feedback, fine-tune the systems, and move into low-rate initial production.”

“Multiple users will test the operational samples, providing critical feedback to aid FN and IWTSD in the final development of the systems,” today’s press release adds.

All this being said, what the exact plan is going forward for the LICC effort, and who might be in line to field the LICC-IWS and/or the LICC-AMG on any level, is not entirely clear. Key to the genesis of the preceding .264 USA cartridge were lessons learned by U.S. forces from combat in Afghanistan during the Global War on Terror era, where being outranged was a common complaint.

“Tactical operators require an integrated, user-tailorable, lightweight shoulder-fired individual weapon and lightweight intermediate caliber cartridge (LICC) that can overmatch the current maximum effective range and terminal effects of peer, near peer, and future threat individual weapons and ammunition, while also defeating current and emerging threat individual protective equipment out to 800 meters,” what was then CCTSO had said in a Broad Agency Announcement (BAA) contracting notice back in 2018.

Since then, the U.S. Army has selected a new standard service rifle and replacement for the M249, the M7 and M250, both from Sig Sauer and chambered to fire a 6.8x51mm round. The Next Generation Squad Weapons program that birthed those weapons was driven heavily by the same concerns about range as LICC, as well as improvements in adversary body armor.

Army special operations units were involved in developmental testing of the M7 and M250, though it remains to be seen how widespread the use of those guns within the broader special operations community might be in the end. The M7 rifle has been the subject of some controversy recently, including criticism about its weight, bulk, and increased recoil compared to the M4A1, as you can read more about here.

In recent years, the U.S. special operations community has also increasingly embraced the 6.5mm Creedmoor round, again because of the increased range, accuracy, and terminal performance it offers over 5.56x45mm, as well as 7.62x51mm. U.S. Special Operations Command (SOCOM) has ordered examples of at least two new rifles in this caliber in the past two years, and has also been evaluating belt-fed machine guns chambered to fire this round.

This all prompts a question of whether the IWTSD is now continuing to pursue LICC with more of an eye toward requirements from foreign allies and partners. As mentioned, Canada is known to be heavily involved in the effort. The 2018 BAA notably used Colt Canada’s C8 Special Forces Weapon (SFW), an AR-15/M16 pattern carbine distinct from the U.S. standard M4A1, as the comparison point for many of the stated LICC requirements. At the time of writing, the LICC-IWS and LICC-AMG pages on FN America’s website notably show the IWTSD logo and the crest of Canadian Special Operations Forces Command (CANSOFCOM).

“With an eye to the future, CANSOFCOM is pursuing a NATO Standardization Agreement (STANAG) for 6.5 x 43 mm in partnership with at least one additional NATO member,” Soldier Systems Daily reported earlier this year, citing unnamed sources. “At this point, the other party has not been disclosed. However, I know it is not the US, which has been working on the 6.8 x 51mm common case cartridge as their path forward.”

Canada has historically been very tight-lipped about its special operations community.

Whatever the case, FN America is clearly continuing to work with the IWTSD to advance the LICC effort, with series production of guns chambered in that round now said to be finally on the horizon.

FORT PIERCE, Fla. — Prosecutors, other attorneys and observers assembled in a federal courtroom Thursday for the start of opening statements in the trial of a man charged with trying to assassinate President Trump while he played golf in South Florida last year, when he was campaigning for a second term.

Ryan Routh is representing himself after U.S. District Judge Aileen Cannon agreed to let him dismiss his court-appointed attorneys. They are, however, standing by in the courtroom if needed.

He has pleaded not guilty to charges of attempting to assassinate a major presidential candidate, assaulting a federal officer and several firearm violations.

Until this week, Routh has appeared at hearings shackled at the wrists and ankles and dressed in a tan jail jumpsuit. But with jurors present, Routh has been unrestrained and dressed in a sport coat and tie. Cannon has said that Routh will be allowed to address jurors and witnesses from a podium, but he will not have free rein of the courtroom.

A panel of 12 jurors and four alternates was sworn in Wednesday, at the federal courthouse in Fort Pierce, Fla. There are four white men, one Black man, six white women, and one Black woman on the jury, and the alternates are two white men and two white women. The panel was selected from a pool of 180 potential jurors.

The trial begins nearly a year after prosecutors say a Secret Service agent thwarted his attempt to shoot the Republican presidential nominee. It’s expected to run two or three weeks. The trial’s start comes as police search for the gunman who killed conservative influencer Charlie Kirk at a campus in Utah on Wednesday in what political leaders are calling an assassination.

Prosecutors have said Routh, 59, methodically plotted for weeks to kill Trump before aiming a rifle through the shrubbery as Trump played golf on Sept. 15, 2024, at his West Palm Beach country club. A Secret Service agent spotted Routh before Trump came into view. Officials said Routh aimed his rifle at the agent, who opened fire, causing Routh to drop his weapon and flee without firing a shot.

Just nine weeks earlier, Trump had survived another attempt on his life while campaigning in Pennsylvania. That gunman had fired eight shots, with one bullet grazing Trump’s ear, before being shot by a Secret Service counter sniper.

Cannon is a Trump-appointed judge who drew scrutiny for her handling of a criminal case accusing Trump of illegally storing classified documents at his Mar-a-Lago estate in Palm Beach. The case became mired in delays as motions piled up over months, and was ultimately dismissed by Cannon last year after she concluded that the special counsel tapped by the Justice Department to investigate Trump was illegally appointed.

Routh was a North Carolina construction worker who in recent years had moved to Hawaii. A self-styled mercenary leader, Routh spoke out to anyone who would listen about his dangerous, sometimes violent plans to insert himself into conflicts around the world, witnesses have told the Associated Press.

In the early days of the war in Ukraine, Routh tried to recruit soldiers from Afghanistan, Moldova and Taiwan to fight the Russians. In his native Greensboro, N.C., he was arrested in 2002 on suspicion of eluding a traffic stop and barricading himself from officers with a fully automatic machine gun and a “weapon of mass destruction,” which turned out to be an explosive with a 10-inch fuse.

Fischer writes for the Associated Press.

WASHINGTON — The massive tax and spending cuts package that President Trump wants on his desk by July 4 would loosen regulations on gun silencers and certain types of rifles and shotguns, advancing a longtime priority of the gun industry as Republican leaders in the House and Senate try to win enough votes to pass the bill.

The guns provision was first requested in the House by Georgia Rep. Andrew Clyde, a Republican gun store owner who had initially opposed the larger tax package. The House bill would remove silencers — called “suppressors” by the gun industry — from a 1930s law that regulates firearms that are considered the most dangerous, eliminating a $200 tax while removing a layer of background checks.

The Senate kept the provision on silencers in its version of the bill and expanded upon it, adding short-barreled, or sawed-off, rifles and shotguns.

Republicans who have long supported the changes, along with the gun industry, say the tax infringes on 2nd Amendment rights. They say silencers are mostly used by hunters and target shooters for sport.

“Burdensome regulations and unconstitutional taxes shouldn’t stand in the way of protecting American gun owners’ hearing,” said Clyde, who owns two gun stores in Georgia and often wears a pin shaped like an assault rifle on his suit lapel.

Democrats are fighting to stop the provision, which was unveiled days after two Minnesota state legislators were shot in their homes, as the bill speeds through the Senate. They argue that loosening regulations on silencers could make it easier for criminals and active shooters to conceal their weapons.

“Parents don’t want silencers on their streets, police don’t want silencers on their streets,” said Senate Democratic leader Chuck Schumer of New York.

The gun language has broad support among Republicans and has received little attention as House Speaker Mike Johnson (R-La.) and Senate Majority Leader John Thune (R-S.D.) work to settle differences within the party on cuts to Medicaid and energy tax credits, among other issues. But it is just one of hundreds of policy and spending items included to entice members to vote for the legislation that could have broad implications if the bill is enacted within weeks, as Trump wants.

Inclusion of the provision is also a sharp turn from the climate in Washington just three years ago when Democrats, like Republicans now, controlled Congress and the White House and pushed through bipartisan gun legislation. The bill increased background checks for some buyers under the age of 21, made it easier to take firearms from potentially dangerous people and sent millions of dollars to mental health services in schools.

Passed in the summer of 2022, just weeks after the shooting of 19 children and two adults at a school in Uvalde, Texas, it was the most significant legislative response to gun violence in decades.

Three years later, as they try to take advantage of their consolidated power in Washington, Republicans are packing as many of their longtime priorities as possible, including the gun legislation, into the massive, wide-ranging bill that Trump has called “beautiful.”

“I’m glad the Senate is joining the House to stand up for the 2nd Amendment and our Constitution, and I will continue to fight for these priorities as the Senate works to pass President Trump’s One Big Beautiful Bill,” said Texas Sen. John Cornyn, who was one of the lead negotiators on the bipartisan gun bill in 2022 but is now facing a primary challenge from the right in his bid for reelection next year.

If the gun provisions remain in the larger legislation and it is passed, silencers and the short-barrel rifles and shotguns would lose an extra layer of regulation that they are subject to under the National Firearms Act, passed in the 1930s in response to concerns about mafia violence. They would still be subject to the same regulations that apply to most other guns — and that includes possible loopholes that allow some gun buyers to avoid background checks when guns are sold privately or online.

Larry Keane of the National Shooting Sports Foundation, who supports the legislation, says changes are aimed at helping target shooters and hunters protect their hearing. He argues that the use of silencers in violent crimes is rare. “All it’s ever intended to do is to reduce the report of the firearm to hearing-safe levels,” Keane says.

Speaking on the floor before the bill passed the House, Rep. Clyde said the bill restores 2nd Amendment rights from “over 90 years of draconian taxes.” Clyde said Johnson included his legislation in the larger bill “with the purest of motive.”

“Who asked for it? I asked,” said Clyde, who ultimately voted for the bill after the gun silencer provision was added.

Clyde was responding to Rep. Maxwell Frost, a 28-year-old Florida Democrat, who went to the floor and demanded to know who was responsible for the gun provision. Frost, who was a gun-control activist before being elected to Congress, called himself a member of the “mass shooting generation” and said the bill would help “gun manufacturers make more money off the death of children and our people.”

Among other concerns, control advocates say less regulation for silencers could make it harder for law enforcement to stop an active shooter.

“There’s a reason silencers have been regulated for nearly a century: They make it much harder for law enforcement and bystanders to react quickly to gunshots,” said John Feinblatt, president of Everytown for Gun Safety.

Schumer and other Democrats are trying to persuade the Senate parliamentarian to drop the language as she reviews the bill for policy provisions that aren’t budget-related.

“Senate Democrats will fight this provision at the parliamentary level and every other level with everything we’ve got,” Schumer said earlier this month.

A man accused of brandishing a rifle at a “No Kings Day” rally in Utah — prompting an armed safety volunteer to open fire and accidentally kill a protester — has been released from jail while the investigation continues.

Salt Lake County Dist. Atty. Sim Gill’s office said Friday that it was unable to make a decision on charges against Arturo Gamboa, who had been jailed on suspicion of murder after the June 14 shooting.

Salt Lake City police had said Gamboa brought an assault-style rifle to the rally and was moving toward the crowd with the weapon raised when a safety volunteer for the event fired three shots, wounding Gamboa and killing a nearby demonstrator, Arthur Folasa Ah Loo.

Gamboa did not fire his rifle and it is unclear what he intended to do with it. His father, Albert Gamboa, told the Associated Press this week that his son was “an innocent guy” who was “in the wrong place at the wrong time.”

Utah is an open-carry state, meaning people who can legally own a firearm are generally allowed to carry it on a public street. The volunteer has not been publicly identified as investigators have worked to determine who was at fault.

Judge James Blanch said in the release order that Gamboa must live with his father and is forbidden from possessing firearms. The conditions terminate after two months or if criminal charges against him are pursued, Blanch wrote.

Gamboa’s attorney, Greg Skordas, did not immediately respond to a telephone message left for him seeking comment.

Police said the day after the shooting that witnesses reported seeing Gamboa lift the rifle when he was ordered to drop it and that instead he began running toward the crowd. He fled but was arrested nearby, accused of creating the dangerous situation that led to Ah Loo’s death.

Salt Lake City police said in a statement the next day that Gamboa “knowingly engaged in conduct … that ultimately caused the death of an innocent community member.”

But three days after Gamboa was booked into jail, with no formal charges filed, police acknowledged that the circumstances surrounding the shooting remained uncertain. They issued a public appeal for any video footage related to the shooting or Gamboa, and said detectives were still trying “to piece together exactly what happened.”

The volunteer who confronted Gamboa was described by event organizers as a military veteran whose role as a safety volunteer was to maintain order.

Experts say it’s extremely rare for such individuals, often called safety marshals, to be armed. They typically rely on calm demeanor, communication and relationships with police and protesters to help keep order, said Edward Maguire, an Arizona State University criminology and criminal justice professor.

Police said the permit for the protest did not specify that there would be armed security.

Protest organizers have not said whether or how the safety volunteer who shot Ah Loo was trained or explained why he was armed. All attendees, including those in safety roles, were asked not to bring weapons, according to Sarah Parker, a national coordinator for the 50501 Movement. Parker’s organization on Thursday said it was disassociating from a local chapter of the group that helped organize the Utah protest.

The demonstration involving some 18,000 people was otherwise peaceful. It was one of hundreds nationwide involving millions of demonstrators against President Trump’s policies — which they likened to the dictatorial actions of a monarch — and his military parade in Washington, which marked the Army’s 250th anniversary and coincided with Trump’s birthday.

Brown writes for the Associated Press.

A demonstrator was shot and killed at Salt Lake City’s “No Kings” protest when a man believed to be part of the event’s peacekeeping team fired at another man allegedly aiming a rifle at protesters, authorities said Sunday.

Police took the alleged rifleman, Arturo Gamboa, 24, into custody Saturday evening on a murder charge, Salt Lake City Police Chief Brian Redd said at a Sunday news conference. The demonstrator, Arthur Folasa Ah Loo, 39, died at the hospital.

Detectives don’t yet know why Gamboa pulled out a rifle or ran from the peacekeepers, but they accused him of creating the dangerous situation that led to Ah Loo’s death. The Associated Press did not immediately find an attorney listed for Gamboa or contact information for his family in public records.

Redd said a man dressed in a brightly colored vest fired three shots from a handgun at Gamboa, inflicting a relatively minor injury but fatally shooting Ah Loo.

The gunshots sent hundreds of protesters running, some hiding behind barriers and fleeing into parking garages and nearby businesses, police said in a statement. “That’s a gun. Come on, come on, get out,” someone can be heard saying in a video posted to social media that appears to show the events.

“No Kings” protests swept across the country Saturday, as millions rallied in cities nationwide against what demonstrators view as President Trump’s monarch-like, authoritarian excesses. Confrontations were largely isolated.

The Utah chapter of the 50501 Movement, which helped organize the protests, said in a statement on Instagram that they condemned the violence.

The Utah chapter did not immediately respond to AP questions about the peacekeeping team. It was unclear who hired the peacekeepers, whether they were volunteers or what their training was prior to the event. Redd said that the peacekeepers’ actions are also part of the investigation.

The shooter and another person in a vest allegedly saw Gamboa separate from the crowd of marchers in downtown Salt Lake City, move behind a wall and withdraw a rifle around 8 p.m., Redd said.

When the two men in vests confronted Gamboa with their handguns drawn, witnesses said Gamboa raised his rifle into a firing position and ran toward the crowd, said Redd.

That’s when one of the men dressed in the bright vests shot three rounds, hitting Gamboa and Ah Loo, said Redd. Gamboa, who police said didn’t have a criminal history, was wounded and treated before being booked into jail.

Police said they recovered an AR-15 style rifle, a gas mask and a backpack at the scene.
