Yhm Crush Washer 1/2" For - 5.56/6.8spc/9mm Ar-15

The Yhm Crush Washer 1/2" for 5.56/6.8spc/9mm AR-15 is a precision crush washer designed for shooters and operators who demand reliable muzzle device timing. This component is essential for ensuring consistent baffle alignment on suppressed or compensated rifle builds, which is critical in both tactical and precision shooting applications.

The crush washer compresses under the torque of muzzle device installation, deforming slightly to absorb rotational tolerance and lock the device in perfect timing. This technique is preferred over shim stacks by many professional gunsmiths and armament technicians. Yankee Hill Machine's engineering ensures that this washer maintains dimensional consistency across standard 1/2x28 applications, delivering repeatable results without the need for secondary timing checks.

This crush washer is beneficial for anyone installing a new muzzle device or rebuilding a suppressed upper receiver, from military armorers to civilian precision shooters. Its compact design requires no special tools beyond a standard 1.5-inch wrench, making it an accessible choice for a wide range of users.
