Precision Armament Accuwasher Aw500 Gen2 Shim Kit - 1/2-28 .725''
$23.74
The Precision Armament Accuwasher AW500 Gen2 Shim Kit in 1/2-28 thread (.725" outer diameter) is a precision muzzle device alignment system designed to replace traditional crush washers with a lathe-turned mono-shim that delivers repeatable timing. If you're running a suppressor, muzzle brake, or flash hider and want your muzzle device clocked exactly where it needs to be—without the guesswork and wobble of old-school crush washers—this is a serious upgrade to your setup.
The key difference here is manufacturing precision. Each shim is machined on both faces to guarantee circular thickness uniformity within .0001", which translates to consistent, centered alignment every time you install your muzzle device. The monolithic steel construction is as strong or stronger than barrel steel itself, meaning it won't shear, slip, or deform under the loads and impacts that can throw lesser shims out of spec. External markings make installation straightforward—you can see exactly where your device will time before you torque it down. And unlike crushable washers that can compress unevenly or leave you guessing about bore concentricity, this system maintains accuracy and gives you the confidence that your suppressor or brake is truly aligned.
The AW500 Gen2 works with suppressors, muzzle brakes, and flash hiders from any manufacturer, so it's a one-size-fits-many solution for your 1/2-28 threaded barrel. Whether you're a precision rifle builder, a suppressor enthusiast, or just tired of dealing with misaligned muzzle devices, this kit removes the variable and puts the responsibility on repeatable, certified geometry instead of hope and experience.

Frequently Asked Questions
Will the Accuwasher Gen2 work with my suppressor or muzzle brake?
Yes. The AW500 Gen2 in 1/2-28 thread is compatible with any brand suppressor, muzzle brake, or flash hider that uses a 1/2-28 connection.
How is this different from a crush washer?
A crush washer compresses unevenly and can leave your muzzle device misaligned. The Accuwasher Gen2 is a precision-machined mono-shim with guaranteed .0001" thickness uniformity on both faces, ensuring your device times consistently and repeatably every time.
Why does thickness uniformity matter?
Uniform thickness ensures the muzzle device seats concentrically and doesn't rock or shift under recoil or impact. This maintains accuracy and reliability, especially with suppressors where bore alignment is critical.
