Ensure Proper Timing on Your .30 Caliber Muzzle Device
Crush washers are essential to replace after removing for replacing a muzzle device. Re-using crush washers can lead to muzzle devices spinning off or becoming misaligned. AT3 offers high quality, machined crush washers finished with a rugged black oxide treatment that will match most new barrels and muzzle devices on the market. Capable of timing up to 360 degrees, this is the part you’ll need if you’re doing up-front work on your AR15.
- Quantity: 1 Crush Washer
- Finish: Black Oxide
- Size: 5/8 Inch (For 5/8-24 barrel threads)
