Spacer for .22lr Silencer use on longer-threaded barrels

Most .22lr silencers have female threads that run around .400 deep, which works on most threaded .22lr firearms. However, if you put these silencers on .22lr conversion kits used on AR15 / M4 type barrels, those 5.56mm carbines are threaded much longer.

This precision-made threaded spacer allows you to use a .22lr silencer on longer thread length barrels. It creates a firm, large shoulder for the suppressor to butt up against, filling the gap that would otherwise be left. It also prevents the extra length of male barrel threads from protruding into the silencer's blast chamber -- where carbon and lead can build up on these exposed threads making it hard to remove the silencer.  This GEMTECH spacer is all you need to make the pieces fit on most any .22lr AR-type type carbine (including the S&W M&P 15-22, which has long, 5.56mm AR-spec threads) and most any .22lr silencers. The spacer threads onto your barrel, and may be installed with adhesive for a semi-permanent solution. Durable steel with wrench flats for removal and assembly, in a blued-black finish.
