Q Rear End XL Brass .338 Caliber 5/8x24

Overview

Q Rear End XL Features The Q Rear End XL carries the same Quickie fast-attach taper mount system trusted across Q s Cherry Bomb and Rear End lineup scaled up to match the bore and performance demands of 8.6 Blackout and paired with Q s Short CHOP and PORQ CHOP silencers for a seamless repeatable suppressor mounting interface that requires no timing or shimming. The addition of wrench flats sets the Rear End XL apart from the original Rear End by providing a straightforward tool-accessible installation and removal experience on 90-degree shouldered barrels eliminating the wrestling match that can accompany taper-mount devices without dedicated wrenching surfaces. For 8.6 Blackout shooters running Q s Short CHOP or PORQ CHOP who want the proven Cherry Bomb mounting system scaled and refined for a larger bore with easier installation the Q Rear End XL is the direct and purpose-built answer. Designed specifically for barrels with 90-degree shoulders the Q Rear End XL delivers the same clean solid lockup and consistent suppressor alignment that the Cherry Bomb platform is known for with no new techniques or hardware required for shooters already familiar with Q s fast-attach muzzle device ecosystem. The 338 bore specification ensures proper clearance and alignment for 8.6 Blackout projectiles across the full performance range of the cartridge and the taper mount system maintains the consistent indexing and repeatable zero that Q s suppressor system demands across multiple hosts and attachment cycles. Shooters building or upgrading an 8.6 Blackout Q suppressor host with 5/8x24 threads and 90-degree shouldered barrels will find the Q Rear End XL for sale at GrabAGun.
