It's a crush washer
Just a basic ol' crush washer. It's nice to buy one from the same shop as everything else on the bill though. I don't know if it's a have-to-have, but at that cost why not?
Used this to install the Ruger PC9 Carbine muzzle break. Easy to use if you look at the short installation video and follow their recommendations.
1/2 x 28 crush washer for pc carbine 9mm
followed the directions on the video and 1st time 3 turns was to much. Good thing I ordered 2. After getting crushed crush washer off, recleaned threads with brass brush placed new crusher washer put in threads taper toward barrel, applied some more rock set and greased end of muzzle break going toward barrel and hand tightened and 2 full turns while in vise and looks great!!!
I lost my washer and tried to replace it with something from Lowes. They had nothing with the quality of this part. I brought extras for all my guns to make sure the caps does not unscrew during firing.
Nice crush washer
I bought this crush washer to use with an A2 flash hider on a Sub 2000. The flash hider has a recess before the threads that make a crush washer unusable. Not a fault of Mcarbo, but I didn't feel there was enough thread engagement before contact. I shimmed it instead. I will use this washer on an AR.
Nice reliable crush from a very good company with good dudes
Had two orders back to back and they condensed my order into one refunding my shipping instead of charging shipping for both. Great company with upstanding dudes. And the crush is a crush and does its job 👍
Worked fine for mounting my A2 flash hider to my Ruger 10/22!
