Precision Armament Accu-Washer® Muzzle Device Alignment System
Simply choose the correct size 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 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 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.
