The STRATOS .22 is the first .22 caliber suppressor of its kind to utilize the proprietary Ambient Intake System. Unlike flow-through suppressors, this all-new category of suppressor technology features intake channels that harness ambient air to drastically reduce post-shooting temperatures, decimate the report of your rifle at both the muzzle and the shooter's ear and materially mitigate unwanted blowback. Firearm not included.
