Lantac Crush Washer – 14mm, AK-47

The Lantac crush washer (brand part no. 01PP141CRW) is sized for 14mm threaded muzzle devices on the AK-47 platform, the small single-use washer that takes up thread play and locks a muzzle device’s timing in the correct clocked position. As the muzzle device is torqued down, the washer physically crushes and compresses, which is what gives it a permanent, non-reusable seat once installed correctly. It ships on a compact card, roughly 3.35 by 2.5 by 0.5 inches, small enough to keep in a range bag or parts bin. AK-47 builders installing any 14mm threaded muzzle device need one of these to get the device indexed straight.
