MUZZLE DEVICE TORQUE

[StanCT]

How much torque (N.m) should I apply when fitting a new muzzle device to an AR?

Do I need to use a new crush washer every time?

Should I be using copaslip on the threads?

You should always use a new crush washer. It deforms, by design, when you fit a muzzle device.

Thank you, SSP.

Copaslip can't hurt.

In my case, with the muzzle brake, I discovered that it's less about torque and more about alignment.

Interestingly, less torque is required than I expected.
