installing a compensator

[1 SIG fan]

on a few AR pattern rifles... Do I need antiseze or just thread it on?

Thanks.

i just thread them on and let the washer do its job

I use loctite and a yardstick to "time" it to the gun. I get the rifle level by sandbagging it and use a yardstick on edge laying on the rail. When my eyeball says the rifle is level I thread on the comp with loctite and lay the yardstick on that to get it level with the rail. When both are level its done. If you dont time the brake the gun will torque roll when fired. Even 1 degree will be felt when shooting.
