The mission at Primary Weapons Systems is to provide the highest quality sporting/tactical rifles and accessories for sportsmen, military, and law enforcement at a fair, competitive price.
The PWS Muzzle Device Alignment Set replaces peel or crush washers commonly shipped with muzzle devices. Hardened steel shims ensure the precise fit and correct alignment of flash suppressors, muzzle brakes, and compensators. Installation is simple, just install the necessary combination of shims to get the precise alignment you require.
Shim 1 allows one half of a rotation or as a spacer for barrels that do not have relief cuts behind the threads.
Shim 2 allows approximately 45 degrees of rotation.
Shim 3 is used when smaller degrees of rotation are needed for proper alignment.
NOTE: This kit is for 5/8×24 threaded barrels.
Kit includes:
- (1) Shim 1
- (8) Shim 2
- (1) Shim 3
