Simply choose the correct size Precision Armament Accu-Washer® shim to accurately index your muzzle brake or flash suppressor while maintaining perfect bore alignment. Since only one shim is required, the tolerance stackups and complexities associated with peel washers and other multi-shim systems are eliminated. This minimizes the risk of baffle strikes, ensuring maximum accuracy and safety from your muzzle brake or suppressor.
Includes 18 individually marked Precision Armament Accu-Washer® shims (timing adjustable from 0-360 degrees in 20-deg increments) and easy to follow instructions. Precision machined from high strength 400 series stainless steel to a guaranteed thickness uniformity of ±0.0001″. All shims feature an oxide blasted non-reflective surface finish for low visibility. One Precision Armament Accu-Washer System will align approximately nine brakes (on average) before replenishment shims are needed. Designed to fit 1/2-28 or 5/8-24 threaded barrels.
Note: The Precision Armament Accu-Washer® Alignment System can be used with any brand muzzle device.
