My first crush washer, First time putting on Muzzle device

by Matt W, Verified Owner from LA, United States Written on May 10, 2023
I bought this to time my Birdcage properly. I put a standard birdcage on my .300 blk and this absolutely worked perfectly. I didn't even need a vice. It crushed down to the perfect timing needed.

Timing = Making sure the muzzle device is in the proper position. You most definitely need this to time your devices.

Good product

by Smith, Verified Owner from VA, United States Written on January 11, 2020
Good product. Doing well so far. It works well. Doing good so far. 200 characters needed for a review. Hard to write so many for a crush washer, haha. Kak Crush Washer is in specifications. The metal is nice and round and able to be crushed well. It works well with their flash cans.
