Precision Armament Accu-Washer 1/2x28

The most precise and easy to use muzzle device alignment system on the market.

Simply choose the correct size Accu-Washer to accurately index your muzzle brake or flash surpressor while maintaining perfect bore alignment. Since only one Accu-Washer is required, the tolerance stackup’s 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 washers (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 washers feature an oxide blasted non-reflective surface finish for low visibility. One Accu-Washer System will align approximately nine brakes (on average) before replenishment washers are needed. Designed to fit 5⁄8−24 threaded barrels.
