CMMG Crush Washer, 1/2″, Black

Product Description

The CMMG AR15 crush washer 1/2″ is an essential component for AR-15 builders and gunsmiths. This precision-engineered washer ensures your muzzle device times correctly. Furthermore, it provides consistent, repeatable alignment on every installation.

The crush washer compresses during tightening to lock your flash hider or muzzle brake in place. Additionally, this compression prevents misalignment and improves both function and appearance. Therefore, your muzzle device will index perfectly without guesswork.

Key Features

This 1/2″ crush washer features durable black finish construction. Moreover, it’s engineered by CMMG, a trusted name in AR-15 components. The washer is designed specifically for standard 1/2″-28 TPI threaded barrels used on most AR-15s.

Whether you’re customizing your first build or upgrading an existing rifle, this crush washer delivers reliable performance. For example, professional gunsmiths stock these for every muzzle device installation. Additionally, home builders appreciate the reliability and ease of use during DIY maintenance and assembly.

Who Should Buy

First-time AR-15 builders benefit from having quality components on hand. Additionally, experienced gunsmiths and armorsmiths rely on CMMG crush washers for consistent results. Furthermore, anyone performing firearm customization or muzzle device upgrades should keep replacements in stock.

Remember: crush washers are designed for single-use installation only. Therefore, you’ll need a new washer each time you remove or change your muzzle device. This ensures proper timing and prevents performance issues every single time.
