I know...aluminum receiver...crap etc. Well since I don't beat my guns the aluminum is just fine and makes the gun somewhat lighter. Does it open all the way to eject holding it up and depressing the button? I don't know, and don't care as I never do that anyway.
I just used that demonstration as a way to show how well the old winchester parts were fit and polished. I am sorry I angered you. Good luck with your choice.
