Eliminate signature, not reliability, by using a suppressor designed to work with your Barrett M107A1. This perfectly-engineered marvel includes a key element no other suppressor has ever incorporated: its own auxiliary two-port muzzle brake which reduces the recoil of suppressed fire. When minimal visible signature is required, the bolted-on auxiliary muzzle brake can be easily removed. The Barrett QDL Suppressor's dual layered tube is constructed of heat treated high strength alloys. This, combined with redundant 360 degree welding, makes it the safest large bore suppressor on the market. By simply sliding the Suppressor over the muzzle brake directly into the indexing point, proper alignment is guaranteed every time. Once in place, the Barrett unique lock-ring coupler clicks into ratchet grooves for a secure fit that nothing can shake. In fact, the entire system is designed to ensure perfect consistency with every installation in seconds. Barrett QDL Suppressor Black Up to .50 BMG - Suppressor Adapter Req. 19247
