I just started my first attempt to put together an Ak 47 9mm Soumi mag pistol and found out the Roger mag wells are no longer available. I need a mag well and an Ak 74 bolt. Any help will be sincerely appreciated. Also anyone who has built one can tell me how much to cut off the bolt back and the bolt extension pointing to the rear trunnion. I have all the parts, receiver built, trunnions in, rails in, and am getting ready to start on the bolt carrier and bolt. I am in Arlington Texas Thank you
