This video from Forgotten Weapons examines the Ambient Arms EXO 5.56 flow-through suppressor during a night vision match. The suppressor features three air intake sets designed to pull in cool air, mix it with combustion gases, and vent it out the front, aiming to keep the suppressor cooler. The test involved firing the suppressor on an FS2000 and observing its heat signature with an infrared camera. While the suppressor showed some minimal IR glow at the rear air intake after a high round count stage, the glow dissipated very quickly, indicating effective cooling compared to traditional suppressors.
