Shivan,
I didn't shoot suppressed as much as you did for the class. I only shot suppressed on the last day (Sunday). But my Norrels on the can held up for the Falluja drill. I went through three mags and only participated once as a shooter not a rescuer (didn't want to hurt my bad back/neck).
I only sprayed the can with Norrels to cover up the scratches that I caused from using Channel Locks to tighten the can down on the original M42000 Mod 07 mount (Phantom type) because that was the only way I could get it to tighten down all the way. With the new Blackout mount it tightens down with just hand strength.
I just took these pics 5min ago.
