AI over any other adapter any day. the gas gun kit comes with everything you need and is the first, the best and the Canadian adapter. AI is good people with a good product and they invented the damn thing and the man is a member here please forget the other brands and support the Canadian manufactures.
Not just brown nosing I have owned 3 different generations of AI adapters and all of them have work perfect. I picked up a new madbull in a trade awhile ago and it was garbage never seemed to seal right no matter what.
