Caliber: .50 BMG - Length Added: 12.73 (32.23 cm) - Diameter: 2.5 (6.35 cm) - Length: 14.84 (37.69 cm) Without Detachable Auxiliary Muzzle Brake - Weight: 4.88 lbs (2.21 kg) - Finish: FDE Cerakote - Total Decibel Reduction: 23 dB - Mount: Quick Detach 1/4 Turn Lock Ring - Materials: 4130 Steel - Eliminate signature not reliability by using a suppressor designed to work with your Barrett M107A1 and with the Model 99 and Model 95 when used with our Muzzle Brake Suppressor Adaptor. The QDL Suppressor is NOT compatible with the Model 82A1. - 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.
