Q LLC | Taper Adapter 1/2-28 | TA-1753-1/2

This taper adapter converts a tapered 1/2-28 muzzle shoulder to a traditional 90° square shoulder to interface with muzzle devices and suppressors that require a flat shoulder. It is intended as a mechanical adapter to allow use of shims or standard-shoulder muzzle accessories on barrels with a tapered muzzle profile. The adapter is manufactured from 17-4 stainless steel and receives a heat-treat coating; color may vary.

Common applications include adapting a tapered muzzle for use with a threaded suppressor that requires a 90° shoulder and fitting muzzle brakes or compensators that need shim space on a tapered shoulder.
