The Primary Weapons Systems PUB-A suppressor hub is a direct-thread mounting solution for pistol suppressors on firearms that don't need a booster. If you're running a pistol-caliber carbine or other fixed-barrel gun with a 1.125-28 threaded suppressor, this hub threads directly onto your muzzle device—no moving parts, no special tools, no booster spring to manage. Just thread it on, and you're ready to shoot. It's built for simplicity and repeatability, giving you consistent alignment every time you mount or remount.
The PUB-A works with the full family of ALPHA-pattern suppressors, including BDE and other common 1.125-28 designs. It's optimized for Primary Weapons Systems FRC muzzle brakes, Q LLC Cherry Bombs, and Rearden devices, though the 1.125-28 thread pattern itself is the real compatibility standard. The tapered interface ensures that precision alignment you expect from PWS—a rock-solid, gas-sealed connection that repeats shot after shot.
This is straightforward suppressor mounting: no complexity, no overengineering, no need to figure out booster timing or spring pressure. If your rifle wears a fixed barrel and a non-booster suppressor, the PUB-A gets out of the way and lets you focus on the shot. Made in the USA and backed by a lifetime guarantee.
