The Precision Armament AccuWasher AW750 Gen2 Shim Kit (brand part no. A00503) covers 1/2-28 threaded barrels that need the largest bore option in the AccuWasher lineup, giving shooters with oversized-bore muzzle devices a way to time them correctly without cutting a crush washer. Its stack of thin, peelable shims can be trimmed down layer by layer, dialing in rotational alignment in fine increments rather than settling for a single approximate fit. Precision Armament built the AW750 to round out the AccuWasher line for the larger-bore devices its own muzzle brakes and comps, as well as other compatible hardware, can require.
