The PWS BDE PUB-A Mount (brand part no. BDE-PUB-A) is a suppressor mount for 1.125-28 threaded pistol suppressors, built by Primary Weapons Systems for the ALPHA thread pattern used on cans such as the BDE 9 and BDE 45. It is optimized for pistol caliber carbines and other fixed-barrel firearms that do not need a suppressor booster. You thread the suppressor on and shoot, with no extra tools and no booster to manage. A precision tapered interface keeps the alignment repeatable and concentric, and the connection is gas-sealed. It is made in the USA and carries PWS’s lifetime guarantee.
