Had it to the range today shooting with open sights at 50 yards. Better than I hoped with my bad eyes and the sights I have on it. About halfway through the session the adjustment knob on the rear sight fell off. Set screw came loose, but the sights didn't move.
I lucked out as far as picking up brass goes. The guy shooting next to me was also shooting 300blk, and wasn't picking up brass. Got to the range with a 100 or so rounds and came home with 200 rounds of brass.
