The AccuWasher Gen 2 Shim Kit is a single mono-shim sized for 1/2x28 barrel threads, so one piece sets the alignment of your muzzle device. It is precision lathe-turned on both faces to a certified circular thickness uniformity of .0001", which takes the guesswork out of muzzle device timing. It fits any brand of 1/2x28 muzzle device, whether you run a muzzle brake or a suppressor. The shim is made from high-strength steel that is comparable to or stronger than barrel steel.

The shim has a .725" outer diameter for 1/2x28 threads. Its external markings make it easy to identify and simplify the alignment process during installation. Each shim is chamfered on one side, which gives clearance for barrels with radiused thread shoulders. Its monolithic construction and substantial thickness help it resist deformation under heavy impact or bending loads.
