AJ Guns External Silencer Booster / Disconnector .578-28 Threaded Connector With 9/16-24 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 9/16-24 on the barrel end to fit most .40SW 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.

  45ACP .578-28 piston is available for purchase in the parts section
