Description
Running one suppressor across several rifles gets old fast when every swap means wrenches and thread wear. The PWS BDE PUB Mount fixes that. It threads into the back of any suppressor with the industry standard 1.375×24 HUB pattern, then snaps onto compatible muzzle devices with a quick, tool-free connection. Put a compatible device on each barrel you own and your can moves from gun to gun in seconds.
What the BDE PUB Mount Works With
Compatibility is the whole point here, and PWS did it right. The PUB Mount attaches to all PWS FRC compensators, plus Q LLC Cherry Bomb and Rearden Manufacturing muzzle devices, along with other Plan B style interfaces. That covers a huge chunk of what's already sitting on muzzles across the country, so there's a decent chance you won't need to buy a single new muzzle device to get started. If you're building from scratch, FRC comps and Rearden devices come in most common thread pitches and calibers.
Why the Tapered Interface Matters
A loose or off-center suppressor is bad news for accuracy and worse news for baffles. The PUB Mount uses a tapered interface that pulls the can into concentric alignment on every install, and the taper doubles as a gas seal to keep carbon from welding everything together. Point of impact shift stays repeatable because the mount seats the same way each time. Machined from 17-4 PH stainless steel with a black finish, it's built to shrug off heat and hard use. One thing worth checking before you order: your suppressor needs at least 3/8 inch of rear thread depth to seat the mount properly.
Making the Most of the PUB System
If you own a HUB can and more than one host, this little piece of stainless is the glue that ties the whole setup together. Screw it in once, torque it down, and forget about it. From there, suppressor swaps take less time than loading a magazine, and you get the same solid lockup whether it's the first round of the day or the five hundredth.

Frequently Asked Questions
Which suppressors does the PWS BDE PUB Mount fit?
It fits any suppressor threaded in the industry standard 1.375×24 HUB pattern, which covers a wide range of modern modular cans. The one requirement worth checking is rear thread depth. Your suppressor needs at least 3/8 inch of thread depth in the back for the mount to seat correctly.
What muzzle devices work with the PUB Mount?
The PUB Mount attaches to all PWS FRC compensators as well as Q LLC Cherry Bomb and Rearden Manufacturing muzzle devices, plus other devices built on the same Plan B style taper. If you already run Cherry Bombs or Rearden brakes on your rifles, this mount drops right into your existing setup.
Do I need tools to attach my suppressor with the BDE PUB Mount?
You'll want to torque the mount into your suppressor once during initial setup, but after that, moving the can between hosts is completely tool-free. The suppressor spins onto the muzzle device by hand and the tapered interface pulls it into a snug, concentric lockup.
Will the PUB Mount affect my point of impact?
The tapered interface is designed to seat the suppressor in the same concentric position on every install, which keeps point of impact shift consistent and repeatable. That means you can confirm your zero with the can mounted and trust it after each swap. The taper also acts as a gas seal, which helps prevent carbon buildup from locking things up over time.
