Installation of KAC MAMS

Make sure you vice the barrel and not the receiver or you damage the upper. You can use a standard wrench with the correct size. Would suggest a adjustable wrench. If your using a crush washer keep in mind those suckers have a lot of give so make sure it's tightened properly. If your using shims you have about a quarter turn after your tight. Don't use locktite, rockset or anything else on the threads. Last time I used rockset took a half hour with a blow torch to get it off.

If you intend to torque your muzzle device at a lower foot pound than you do your barrel nut, is it still possible to move the barrel when tightening the muzzle device?

New to assembling AR's, and I shudder to think of what I've done wrong so far! ;)
