Went to this great unsupervised range in Warrenton, MO yesterday. It was fun because I could do some rapid fire stuff with the gun that they frown upon at the highly structured range I shoot at normally. Man, it ran like a champ. I had my first failure to feed, but I was fooling around and probably limp wristed it. I've probably got around 300+ rounds through it now and it just keeps getting smoother and better. I love this gun!
