Just ordered this setup for my rifle, do I need crush washers or anything for proper fitting of brake?
Tks
I just installed a surefire War Comp. It installed via shims and not crush washer
Included? Or separate purchase?
also, pending on which muzzle device you bought, you may need a thin armourers wrench. the slots are small and a regular 3/4 wrench wont fit.
