AJ Guns External Silencer Booster / Disconnector .578-28 Threaded Connector With 16x1MM Piston

No FFL or Tax Stamp Is Required For This Item. Ships Directly To Your Door.








Our external booster assembly is made of 316L stainless steel for a lifetime of problem free use. Ships with a heavy spring installed and a spare medium spring in the bag.
The booster piston is threaded 16x1MM on the barrel end to fit most European made 45ACP barrels.
The booster is threaded .578-28 on the silencer end to fit most silencers threaded for 40SW and 45ACP applications. Turn your rifle silencer into a pistol silencer. Quick and easy screw on installation.

A booster is required for all handguns that utilize the Browning-type action (Glock, Sig, HK, S&W etc.) The use of the booster allows the pistol to properly cycle when the weight of the suppressor is added to the end of the barrel.

40SW 9/16-24 piston is available for purchase in the parts section
