Barrel Thread Adapter – 578-28 (45 Cal) To ASR


This adapter is for a barrel thread pitch .578-28 to accept ASR threaded devices such as silencers from SilencerCo. Inner diameter of device is .45 Cal. Calibers smaller than .45 with the correct barrel thread pitch will work with this adapter.  A single use tube of Rocksett adhesive, by Flexbar, is included!  At the bottom of this page is a link to purchase Rocksett.  If you are enough of a tinkerer to use this muzzle device, we highly recommend you have a bottle of Rocksett handy rather than just a single-use container.

Benefit: If you will be running a silencer 100% of the time, there is little to no added benefit for having a muzzle brake or flash hider on the barrel.

Materials: Made of 4140 Alloy Steel. Toleranced tightly to .002″ for all critical angles and geometries. Finished with bead blast for comfort and ergonomics and mil-spec black oxide for superior corrosion resistance. Designed and manufactured in Minnesota, USA.
