IMPORTANT: These are individually sold Accu-Washer shims. They are intended only for replacing shims used from the full 18 shim set which you must always purchase first. You WILL NOT be able to index or align your muzzle device by purchasing a single Accu-Washer shim.

You must always purchase the full 18 shim set for first time installations. Please refer to Accu-Washer Muzzle Device Alignment System if you have not purchased the full 18 shim set in the past.

    Precision Armamaments Accu-Washer Shim system is by far the best way to time a silencer mount or muzzle device on all your threaded firearms. We won't use anything else!
