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.

Specifications

  • Quantity: 1 Crush Washer
  • Finish: Black Oxide
  • Size: 5/8 Inch (For 5/8-24 barrel threads)

worth it!

this little compensator is of very nice workmanship and quality. Works as it should and a bit nicer than just a flash can.

Installation Hints?

Installation Hint? Crush Washer is dished on one side and flat on the other. Which side goes against the barrel and which side goes towards the Muzzle device? How much Torque should one apply or not apply when installing? .Also bought a muzzle brake. Neither item came with any sort of diagram or instruction. Excuse me for not knowing any better but a little information included with your parts would probably be appreciated by more people than just me.

I always use this to correctly orient my muzzle device or to keep my suppressor from backing off from vibrating

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

Too small

Unfortunately they didn’t fit over the threads of either of my 5/8-24 threaded barrels. Shipping was super fast and other products from AT3 were great

Sorry to hear about the trouble, Josh. We sent you an email to resolve the issue.
