Frequently Asked Questions

Why should I avoid using a crush washer with a silencer?

Crush washers deform unevenly, which can misalign your muzzle device. This misalignment is magnified by the suppressor, increasing the risk of baffle strikes that can destroy your silencer and potentially damage your firearm.

What is the recommended alternative to a crush washer for muzzle device installation?

The recommended alternative is a shim kit. Shims allow for precise timing and alignment of the muzzle device without the uneven deformation associated with crush washers, ensuring proper suppressor compatibility.

What type of thread locker should I use for muzzle device installation?

Use high-temperature resistant thread lockers like Rocksett or green Vibra-Tite. Avoid blue Loctite, as it can melt under the heat generated by suppressed fire, potentially causing the muzzle device to loosen.

What are common muzzle device thread pitches?

Common thread pitches include 1/2x28, typically used for 5.56mm caliber firearms, and 5/8x24, commonly found on .30 caliber firearms. Always ensure compatibility with your barrel.
