The Precision Armament AccuWasher AW500 Gen2 Gunsmith Kit is a shim kit for timing muzzle devices on 1/2x28 threads, so you can index a brake or flash hider without guesswork. It is a single-shim system, which gives you better alignment, accuracy and repeatability than crush washers or stacks of multiple shims. The Gen2 shims have a reduced 0.725" outside diameter, and that smaller size gives a more flush fit and finish with adapters.

Each kit holds 5 shims, so you have a range of sizes on hand for different timing positions. A rugged organizer case with separate compartments keeps the shims sorted and easy to find at the bench. The label carries a QR code that lets you restock individual shim sizes quickly, which helps if you time devices in volume. Precision Armament lists the kit as a Shim Kit with a 1/2 X 28 thread pattern.
