Do you have any experience to back up your claims? I put somewhere north of 10k rounds through a yildiz 12ga. Probably a third of that was shooting steel shot while duck hunting the rest was skeet and sporting clays. The only issue I ever experienced was the injectors sticking after getting it muddy and wet through a whole duck season without cleaning it. I now own a yildiz 20ga. It doesn't have many rounds through it, but it gives every indication of being a great gun. I can count numerous times where Beneli and beretta autos failed to function in a duck blind, but only 1 instance of injectors causing me about 10 seconds of grief with the yildiz. There are some very nice o/u out there. Certainly some of them point better than a yildiz, have a better fit and finish, or maybe even have a slight edge in reliability. There is absolutely not a wide margin in functionality, and that's backed up by damn near every review you can find on the Internet.
