The Q Rearend XL Muzzle Brake is a Quickie Fast-Attach muzzle brake built for 8.6 BLK and scaled up from the original Rear End to handle the thump and authority of the larger cartridge. Its 5/8x24 threading suits 338 caliber barrels, and the Quickie Fast-Attach system lets a silencer be mounted and removed quickly.
It runs with Q SHORT CHOP and PORQ CHOP silencers and is designed for barrels with 90-degree shoulders. The tapered mount system holds the attachment secure, and wrench flats make installation easier.
