Feel like dropping the volume on your AR-15? The Idaho-based suppressor company Gemtech and the Montana-based Nemo Arms have what you’re looking for: a new integrally suppressed barrel for your rifle. Unveiled earlier this year at the NRA meeting in Atlanta, the Gemtech Integra is available in both 5.56x45mm and .300 Blackout.
Gemtech’s Integra sports a Nemo Arms-manufactured 10.5-inch barrel and a six-inch titanium monocore baffle insert that uses advanced fluid dynamics to capture and slow propellant gases, helping to quiet your gun down. The company claims the Integra can reduce your rifle’s report by an impressive amount: as much as 25 decibels. According to Gemtech, the 5.56 barrel registers at 131 decibels. The .300 Blackout, when used with subsonic ammunition, is slightly quieter: about 128 decibels.
Let’s be honest: The real draw of integrally suppressed barrels like the Integra is that they allow you to rock a short, suppressed package without having to pay the short-barreled rifle tax stamp. You get the best of both worlds: a slick setup that still meets the minimum overall length requirement. Combined, the barrel and suppressor give the Integra an overall length of 16 inches. It comes encased in a titanium body, inside a handguard from Seekins Precision, which has a full-length top rail and M-LOK slots on both the sides and the bottom.

Equipped with a pistol-length gas system, the Integra’s patented gas block has a bore evacuator that vents the cartridge combustion gases, reducing gas blowback at the shooter’s face. It’s also easy to take care of. The suppressor, which is only a single piece of machined titanium, comes out easily for cleaning — all you need is a 3/8″ socket wrench to remove it.
The Gemtech is part of a new generation of integral suppressors that companies like SilencerCo and Ruger are offering. It may not cheap — both the 5.56 and .300 Blackout versions sell for $1,999 (plus the additional mandatory Federal tax stamp) — but if you’re looking for quiet power, it’s worth it.

This type of small UAV was used by cadets and midshipmen from the U.S. Air Force Academy, the U.S. Military Academy and the U.S. Naval Academy, during a Defense Advanced Research Projects Agency-sponsored competition at Camp Roberts, California, April 23-25, 2017. During the competition, cadets and midshipmen controlled small UAVs in "swarm" formations to guard territory on the ground at Camp Roberts. (U.S. Air Force photo)
Drones have been used in conflicts across the globe and will play an even more important role in the future of warfare. But, the future of drones in combat will be different than what we have seen before.
The U.S. military can set itself apart from others by embracing autonomous drone warfare through swarming — attacking an enemy from multiple directions through dispersed and pulsing attacks. There is already work being done in this area: The U.S. military tested its own drone swarm in 2017, and the UK announced this week it would fund research into drone swarms that could potentially overwhelm enemy air defenses.
I propose we look to the amoeba, a single-celled organism, as a model for autonomous drones in swarm warfare. If we were to use the amoeba as this model, then we could mimic how the organism propels itself by changing the structure of its body with the purpose of swarming and destroying an enemy.

The Army has awarded a $575 million contract to BAE Systems for the initial production of its replacement for the M113 armored personnel carriers the service has been rocking downrange since the Vietnam War.
President Donald Trump has formally outlined how his administration plans to stand up the Space Force as the sixth U.S. military service – if Congress approves.
On Tuesday, Trump signed a directive that calls for the Defense Department to submit a proposal to Congress that would make Space Force fall under Department of the Air Force, a senior administration official said.
