1/2 x 28 Crush Washer - .22LR / .223 / 5.56 / 9mm
- Includes one 1/2 x 28 Crush Washer for installing Muzzle Brake, Compensator or Flash Hider
Crush Washers are made from special engineered, heat treated steel that has been fine tuned and balanced between high spring rate and ductility to meet the function requirement of "crushed with high spring tension without cracking".
This crush washer is designed for AR-15 flash hider, muzzle brake or compensator installation on barrels with a 1/2x28 thread. This crush washer will fit every standard AR15 on the market chambered in 5.56/.223, as well as all pistol/rifles chambered in .22LR and 9mm.
NOTE: Crush washers are only intended to be used (1) time. Using a crush washer multiple times will decrease the effectiveness of the washer.
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!
Crush washers for 1/2-28 threads
I am no longer an advocate of naked barrel muzzle jumping platforms. I even install brakes on my 6.5mm Creedmoor builds to stop muzzle jump. Quicker more accurate follow up shots. To assist a GOOD installation index for great control a good crush washer and temper is required. These are very consistent and easier to get the proper crush. I highly recommend them. I will continue to use MCARBO for this product.
