LANTAC USA Crush Washer 14mm AK-47

The LANTAC USA 14mm Crush Washer is a precision installation accessory designed for proper timing and alignment of AK-47 flash hiders, muzzle brakes, and compensators on barrels with a 14mm thread. Manufactured in the USA, this washer installs between the barrel shoulder and the muzzle device, where it deforms under torque to lock the device at the correct orientation with ports, slots, or prongs aligned for optimal recoil management.

During installation, the crush washer is positioned on the barrel threads before the muzzle device is threaded on. As the device is tightened, the washer compresses and slightly deforms, allowing the installer to fine-tune the final position by adjusting torque. Once the desired alignment is locked in, the washer holds the device securely in place. This is a single-use component - once compressed, it cannot be reused without compromising the timing of the attached device.

Designed for the standard 14mm AK-pattern thread, this is the correct choice when installing or replacing flash hiders, muzzle brakes, or compensators on any AK-47 variant.
