FREQUENTLY ASKED QUESTIONS

 

The AccuWasher® Gen 2 is an upgraded version of the Precision Armament original single-shim muzzle device alignment system. It allows for precise, repeatable alignment of muzzle brakes, compensators, and suppressor mounts—eliminating the guesswork and inconsistency of peel washers and crush washers. Gen 2 features new shim sizes, thinner profiles, and adapter compatibility for broader use across different thread sizes and barrel profiles.

The Gen 2 system offers several improvements over the original:

Feature Gen 1 Gen 2
Shim Sizes 1/2” and 5/8” kits only Now includes 1/2”, 5/8”, and 3/4” kits
Outside Diameter (OD) 1/2” shim: 0.750” 1/2” shim: 0.725” (smaller for a sleeker fit)
Shim Thickness 5/8” shim: 0.060”-0.100” 5/8” shim: 0.040”-0.080” (thinner for finer adjustment)
Compatibility Limited to fixed thread sizes Now compatible with all common thread sizes and barrel profiles via shim adapters
Interchangeability 1/2” shims are compatible 5/8” Gen 1 and Gen 2 shims are not interchangeable
Aesthetic Standard fit More flush and professional finish with adapters

Each shim is laser-marked with a series of thick and thin dashes:

  • Thick dashes = 5
  • Thin Dashes = 1
    For example, a shim with 4 thick dashes and 1 thin dash equals shim #21.

Use the included timing chart to determine which shim number aligns your muzzle device properly.

Absolutely. Despite all the added features and compatibility improvements, Gen 2 maintains the single-shim design, which offers better alignment, accuracy, and repeatability compared to systems requiring multiple stacked shims.

We've created an easy-to-follow and detailed instruction manual with a printable timing chart. If you have questions, feel free to contact our service team:
