The 338 ULTRA SR is our latest high-performance .338 caliber suppressor. It offers class leading suppression levels, a light weight design, and our "SR" quick attach/detach mount that offers locking Secondary Retention.
The 338 ULTRA SR will suppress a typical .338 Lapua Magnum bolt-action rifle down to approximately 135-138 dB at the muzzle1, and approximately 124-128 dB at the shooter's ear 2. It also has very little or no "first round pop" (FRP) in most applications.
The 338 ULTRA SR weighs 20.2 ounces including the SR mount mechanism on the suppressor itself. The SR brake weighs 3.6 ounces. It is only compatible with the 338 ULTRA SR series of brakes and flash hiders.
