Picked up 10 of these mags for kicks thinking I was going to do something with them and decided not to. They are all brand new in box from AR-57 and fit the AR-57 or PS-90 platforms. I will entertain selling them if the offer is right. Been watching GB and they seem to be going up quickly. They are the smoked finish ones and 50 round capacity. Trade offers would probably include Savage 22 rifles or 22 pistols. Can add cash for the right deal. Pictures up soon.
