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

(1 customer review)


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, including 10mm.  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 instead of this muzzle device, and many pistol caliber carbines do not have additional muzzle devices ship with their threaded barrel from the factory due to the nature of the pistol cartridge pressures.

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.

    Great Product! Only solution out there for CMMG Banshees in 45 ACP and 10MM. Works fantastic. I use it with a SilencerCo Hybrid 46 on a CMMG Banshee in 45. Going to buy a 2nd one from Patnik, because this platform is so nice, I’m going to buy another Banshee in 10mm.
