AR15 223 SHIM SET 10 STK SET

Ensures Correct Alignment For Flash Hiders & Muzzle Brakes

Hardened steel shims ensure precise fit and correct alignment of flash suppressors, muzzle brakes, 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.

SPECS: Steel. Sold in 10 paks (1 small, 1 large, 8 medium). .223 - .748" O.D. Fits muzzles threaded ½"-28 tpi.
