Description

Q scaled up its Quickie Fast-Attach system to keep pace with the bigger bore and extra gas pressure that comes with 8.6 BLK and other .338 caliber loads, and the Rearend XL is the result. It's built on the same taper mount design that made the original Rear End and Cherry Bomb a go-to for suppressor mounting, just beefed up to handle the added authority of a bigger cartridge. If you're setting up a .338 build and want a brake that mounts hard and repeats the same lockup every time, this is the piece Q designed with that exact job in mind.

Rearend XL Suppressor Compatibility

This brake threads onto M18x1.5 barrels and is built to run directly with Q's Short Chop and Porq Chop suppressors, both of which actually ship with this same XL Cherry Bomb style brake already installed. It'll also work with any other can running Q's Plan-B mount system. Since it's a taper mount, there's no shimming or timing needed to get everything centered, so you're not chasing a shift in point of impact every time you pull the suppressor off and put it back on.

Rearend XL Mounting and Shoulder Design

Where the standard Cherry Bomb needs a tapered barrel shoulder, the Rearend XL is built for a standard 90-degree shoulder, so it fits onto typical factory and aftermarket .338 barrel contours without any special machining. A 9/16 inch socket pocket up front is the preferred way to get it on and off, and Q recommends a 3/8 inch drive socket for the cleanest fit in that pocket. Rear wrench flats are there as a backup for the times carbon buildup or a stubborn suppressor makes things fight back a little.

Built to Handle 8.6 BLK Recoil

Machined from 17-4 stainless steel, the Rearend XL is built to hold up to sustained fire from a hard-hitting .338 caliber rifle without losing its edge. Whether you're running it bare to knock down recoil and muzzle rise on an unsuppressed 8.6 BLK build, or using it as the mounting point for a suppressed setup, it's designed to hold zero and lock up the same way round after round.

Frequently Asked Questions

What suppressors work with the Q Rearend XL muzzle brake?

It's built specifically to run with Q's Short Chop and Porq Chop suppressors, both of which use this same XL Cherry Bomb style brake as their mounting interface. It will also work with any other suppressor running Q's Plan-B mount system, so you're not locked into just those two cans.

Does the Rearend XL need a tapered barrel shoulder?

No. Unlike the standard Cherry Bomb, the Rearend XL is built for barrels with a standard 90-degree shoulder, so it fits most factory and aftermarket .338 barrels without a special contour. That makes it a more universal option if your barrel wasn't cut specifically for a tapered mount.

What tools do I need to install the Rearend XL?

The front 9/16 inch socket pocket is the preferred install and removal method, and Q recommends using a 3/8 inch drive socket for the tightest fit. Rear wrench flats are also included as a backup in case the mount ever gets stubborn or stuck in the suppressor.

Can the Rearend XL be used without a suppressor?

Yes, it functions as a standalone muzzle brake even when nothing is mounted to it, helping tame recoil and muzzle rise on 8.6 BLK and other .338 caliber builds. It doubles as thread protection for the barrel when you're not running it suppressed.
