The Rear End XL by Q is the Quickie Fast-Attach muzzle brake built specifically for the 8.6 BLK and designed to run seamlessly with our SHORT CHOP and PORQ CHOP silencers. Same DNA as the original Rear End, just scaled up to handle the thump and authority of 8.6.

Like all Rear Ends, the XL features a 90° shoulder for rock-solid lockup and wrench flats in the rear—because sometimes your Rear End needs a little persuasion. We also integrated the classic 9/16” socket pocket in the front, which is the preferred method for install/uninstall. Rear flats? They’re just backup, in case your Rear End decides to stay stuck in your silencer a little too long.

Recommended Tools:
Not all sockets are created equal. We recommend a 3/8" drive socket for the front pocket—tight, consistent fit for the Rear End XL.
