      We sincerely apologize for the shipping delays. The covid panic buying in March of 2020 was something we had never experienced before. Before that orders were going out within 1-3 days. Since then we have completely restructured our shipping department so this never happens again.

    It’s a crush washer…..umm…works just like all the rest I have.

  29. Jeff M. (verified owner)

    does what its supposed to

  30. Anthony B. (verified owner)

    these crush rings work perfectly they aren’t too soft like many crush washers out there. They allow you to get your muzzle device tight. You won’t have to worry about loose flash hiders with these crush rings.
