Primary Weapons Systems BDE PUB-A Suppressor Mount, HUB Compatible, Black
This is the ALPHA-thread version of the PWS PUB mount, adapting ALPHA-pattern pistol-caliber suppressors to a PWS-style HUB muzzle device — built for pistol cans and PCC setups. The tapered interface centers the suppressor with a tool-free, repeatable lockup every time, torqued to 25-35 ft-lbs.

What’s the difference between this and the PUB XL mount you sell?
The PUB-A is the ALPHA-thread pattern built for pistol-caliber suppressors and PCC setups, while the PUB XL is sized for larger rifle-caliber HUB-compatible suppressors — they’re not interchangeable.
Do I need tools to attach or remove my suppressor with this mount?
No, the tapered interface gives a tool-free, repeatable, concentric lockup — just thread it on and torque to spec.
What torque should I use when installing this?
PWS specifies 25-35 ft-lbs maximum for this mount.
What muzzle devices does this work with?
It mounts to PWS FRC compensators and other HUB-pattern muzzle devices, including options from Q and Rearden — confirm your specific muzzle device is HUB-compatible before ordering.
Will this work with a rifle-caliber suppressor?
No, the ALPHA-thread pattern on this mount is built specifically for pistol-caliber suppressors and PCC setups, not rifle-caliber cans.
Does this mount include the suppressor or muzzle device?
No, this is the mount only — the suppressor and any HUB-compatible muzzle device are sold separately.
