Scott Wilson, member, from CA, United States, asked on February 19, 2024

The crush washer is different than traditional ones. Any idea which was it goes on?

Manufacturer Answer

Answered by Faxon Firearms, Manufacturer from OH, United States, on November 27, 2024

The "nub" side should be facing towards the muzzle thread shoulder. Here are the install instructions:

To install your slim muzzle device, follow the instructions below:

Install the crush washer onto the barrel with the thinner "nub" side facing the muzzle threads shoulder.
Lightly thread on the muzzle until it just starts exerting pressure on the crush washer with your hands.
Use the flats to the muzzle device to slowly turn the muzzle device until it is timed. These custom crush washers only have about 230° of crush, so once one side is aligned - STOP!

It is listed as 21/4 ", is that a net length? i.e. will it make a 14" gunner barrel 16 1/4" or will the thread overlap make it sub 16"?

Expert Answer

Answered by Kurt Colbourne, Gear Expert, from IL, United States, on April 01, 2021
