Overall, for a high end mechanical gun it performs VERY well. We didn't chop a single ball when we tested it and it worked like a dream. Its just a fun gun to shoot, it looks damn near the same as a real HK G36 minus the hopper. I'll tell you this much, I've already put an order in for one myself for the next big game coming up this summer. Its a good change for us tournament guys to do something different now and then and get away from the 1 minute games.
