Special operators could soon rock a new suppressor that relies on WWI technology

LAS VEGAS -- Radical Firearms has unveiled its new machine-gun suppressor, which was recently selected to be evaluated under a Joint Special Operations Command (JSOC) program.


The new 240 FVS Machine Gun Suppressor, tailored for the M240 machine gun, is designed to drastically exceed special-operations forces' performance requirements, Mel Miranda, marketing director for military and law enforcement sales at Radical Firearms, said at SHOT Show 2020.

The 3D-printed 240 FVS suppressor can handle up to 1,500 rounds of continuous M240 fire, far exceeding the JSOC suppressor requirement for 600 rounds of continuous fire, Miranda said.

It runs 250 to 300 degrees cooler than other suppressors on the market, said David Spector, chief operating officer for Radical Firearms.

"It creates an open flow of air, so that as you are shooting this weapon with a 1,000-round belt, you can go into a firefight and not melt the suppressor," Spector said. "You will melt the barrel down before you melt the suppressor."

Officials from the Naval Surface Warfare Center's Crane, Indiana division tapped the 240 FVS for future evaluation at the Special Operations Forces Warrior Operational Requirements Discussion Symposium (SWORDS) in Tampa, Florida, in early November, Spector said.

"They have approached us and requested the suppressor for testing," he said.

The 240 FVS operates on the same principle as the 1906 Lewis, a light machine gun that saw extensive use during World War I, Spector said.

"It creates a high-pressure shock wave in the machine gun itself and pulls air through it to cool the machine gun," he said. "This is an air-cooled suppressor; it's based off the Lewis Gun."

That type of technology has been abandoned for years, Spector explained.

"Firms have gone to more robust materials ... and they think that they can defeat heat. Well, heat is a booger," he said. "Additive manufacturing allows you to ... eliminate traditional machining, and it's kind of the sky's the limit."

Spector admits that the 240 FVS is "actually pretty heavy" at four pounds, but he is confident that it outperforms other suppressors on the market.

"When we have done testing ... some of these other cans that say 'they breathe and do things' -- they actually run really hot and they start melting," he said.

The 240 FVS is designed to form what is known as the Venturi effect, which creates a vacuum for heat and pressure.

"Whenever a round passes through the barrel to the suppressor, an explosion occurs right at the beginning of the suppressor," Spector said.

"What we do with this suppressor is we stop back pressure on the barrel and the bolt by creating a secondary channel which ... vents out of the front," he said, explaining how the suppressor forces cooler air through with each round fired.

"With this, you have air channeling over the entire suppressor, pulling that heat away from the suppressor," Spector said.

Though the Army has yet to actually set an official recruiting goal for this year, leaders are confident they're going to bring in more soldiers than last year.

Maj. Gen. Frank Muth, head of Army Recruiting Command, told reporters on Wednesday that the Army was currently 2,226 contracts ahead of where it was in 2019.

"I will just tell you that this time last year we were in the red, and now we're in the green which is — the momentum's there and we see it continuing throughout the end of the year," Muth said, adding that the service hit recruiting numbers in February that haven't been hit during that month since 2014.

We are women veterans who have served in the Army, Navy, and Marine Corps. Our service – as aviators, ship drivers, intelligence analysts, engineers, professors, and diplomats — spans decades. We have served in times of peace and war, separated from our families and loved ones. We are proud of our accomplishments, particularly as many were earned while immersed in a military culture that often ignores and demeans women's contributions. We are veterans.

Yet we recognize that as we grew as leaders over time, we often failed to challenge or even question this culture. It took decades for us to recognize that our individual successes came despite this culture and the damage it caused us and the women who follow in our footsteps. The easier course has always been to tolerate insulting, discriminatory, and harmful behavior toward women veterans and service members and to cling to the idea that 'a few bad apples' do not reflect the attitudes of the whole.

Recent allegations that Secretary of Veterans Affairs Robert Wilkie allegedly sought to intentionally discredit a female veteran who reported a sexual assault at a VA medical center allow no such pretense.

Active-duty service members, Reservists and National Guard members often serve side-by-side performing highly skilled and dangerous jobs, such as parachuting, explosives demolition and flight deck operations.

Reservists and Guard members are required to undergo the same training as specialized active-duty troops, and they face the same risks. Yet the extra incentive pay they receive for their work — called hazardous duty incentive pay — is merely a fraction of what their active-duty counterparts receive for performing the same job.

A bipartisan group of lawmakers, led by U.S. Rep. Andy Kim, D-3 of Moorestown, are partnering on legislation to correct the inequity. Known as the Guard and Reserve Hazard Duty Pay Equity Act, the bill seeks to standardize payment of hazardous duty incentive pay for all members of the armed services, including Reserve and National Guard components.
