The Yankee Hill Machine Low Profile Crush Washer (Model YHM-24-W) is a precision-engineered accessory designed to ensure proper installation and timing of muzzle devices on threaded barrels. This high-quality crush washer is specifically manufactured for use with 1/2x28 threaded barrels, the most common thread pattern found on AR-15 rifles and many other modern sporting rifles chambered in .223 Remington and 5.56 NATO. When installing flash hiders, compensators, or muzzle brakes, the YHM-24-W provides the necessary compression to securely lock the device in the correct orientation while protecting the threads on your barrel.
Essential for Proper Muzzle Device Installation
A crush washer is a critical component when mounting any muzzle device that requires precise timing, such as an A2-style flash hider or a three-prong flash suppressor. Unlike a standard flat washer, a crush washer is designed to deform slightly under torque, creating a secure lock that prevents the muzzle device from loosening during firing. The low-profile design of the YHM-24-W minimizes added length to the barrel, making it ideal for builds where overall length is a concern, such as short-barreled rifles or pistols.
Yankee Hill Machine is known for producing durable, American-made firearm accessories. The YHM-24-W is manufactured from high-strength steel and finished to resist corrosion, ensuring reliable performance even in harsh conditions.
