    Booster for R9 Suppressor

    Posted by Jackson Collins on May 5th 2023

    I have a YHM R9 suppressor and run it on my S&W M&P 2.0 (9mm). Using the suppressor by itself doesn't allow for full ejection of the casing, therefore the gun will not fully cycle. The booster easily attaches to the suppressor and allows for successful semi-automatic fire with the suppressor. Make sure you buy the piston as well, which is part # YHM-2060.

    This is mandatory for a handgun. Now my R9 hooks up to my pistols with threaded barrels.
