Strike Industries Muzzle Device Alignment Shim Kit


Align your AR-15's muzzle device efficiently and accurately with Strike Industries' 1/2-28 shim kit.

Install Devices Efficiently and Accurately

When choosing to install a muzzle device on your AR-15, trying to align it accurately with a standard crush washer can be time-consuming. By using the Strike Industries 1/2-28 shim kit, installing a muzzle device properly the first time becomes very achievable.

Designed to be Durable for Long Term Use

Crush washers are sometimes used for muzzle alignment, but they do not guarantee proper alignment and are usually only suitable for one use. However, you do not have to settle for crush washers; this 1/2-28 shim kit offers a robust solution. The Strike Industries shim washers are made into one solid piece from durable SUS 304 stainless steel to achieve the longevity that is needed to withstand long-term use effectively.

Good Value that Helps You be Prepared

The strong construction aforementioned makes these washers reusable, which makes this shim kit an excellent value. Further, the kit includes shims of varying thickness so that you have the size you need readily available.
