    Crush Washer question

    So I believe these things do not exist in a retail setting. I need one for my AR barrel that is .925 diameter to fit my JPTactical brake on it....Since I guess I didn't read the directions before I purchased....who knew? Anyone know where I can get one? (besides online) Ive tried local hardware stores, lowes, and NAPA and no luck. The local gun shop has only for .750 diameter which would look bad on it. So am I just out of luck and going to get screwed on shipping for a $3 item or what.

    Not sure exactly what you are looking for but try grainger.com they will have crush washers and you can set up an account and pick up in a local store

    Are you better off than you were four years ago?

      Unless your .920 barrel has no muzzle threads, barrel diameter is not the diameter of the threaded muzzle, which will remain universal for ar15's, and only slightly larger for ar10's.

      Any competent gun store that deals in AR's should have crushers.

But the traitor moves amongst those within the gate freely, his sly whispers rustling through all the alleys, heard in the very halls of government itself...A murderer is less to fear. The traitor is the plague."......Cicero

          Just make sure to buy three when you find them, better to have and not need.

            The JP barrel and brake are meant to be timed and fitted as one piece, no crush washer. Just sand the brake until it times correctly. When done by JP they even polish it to look like one solid piece.

                Yeah, what Joe said.

                JP brakes are meant to be installed by gunsmiths, generally using a lathe to set the timing. They're not just a crush-washer job like other brakes.
