Primary Weapons Systems PWS AR Muzzle Device Shim Kit .223 AR15 or 7.62 AR10

Ensures Correct Alignment For Flash Hiders & Muzzle Brakes

Hardened steel shims ensure precise fit and correct alignment of flash suppressors, muzzle brakes, barrel sleeves and compensators. Large (thick) shim allows 90° of rotation and can be used as a spacer for barrels not having a relief cut behind the threads. Medium shims add approximately 45° of rotation. Small shims used with large and medium shims provide smaller degrees of rotation for finely-tuned, critical alignment. Each shim kit includes 1 large, 1 medium and 8 small shims.
