The Ambient Arms EXO 5.56 is the coolest 5.56 suppressor ever made, literally. 3D-printed from titanium and built around Ambient Arms’ proprietary Ambient Intake™ System, the EXO 5.56 pulls cool outside air into the can to run dramatically cooler after firing, while also reducing blowback and keeping the rifle’s report down at both the muzzle and the shooter’s ear. It’s a low back-pressure design aimed at smoother cycling on semi-auto AR platforms (less port noise, less gas in the face, and more consistent bolt speed), and the intake/low-pressure architecture is designed to minimize turbulence on the projectile for tight, repeatable accuracy.
The EXO uses a HUB-compatible rear, measures 6.9” long and 1.75” in diameter, and weighs 14.5 oz (without mount). Rated for barrels 10.3″ or longer for 5.56 / .223 Wylde / 6mm ARC, full-auto rated, SOCOM surge-test verified, with a recommended detailed cleaning every 2,500 rounds.
