I am wanting to sell this redi-mag system that I got in on a trade from a buddy of mine. It does have a SN lightly etched into it. But I looks like it would be very easy to paint over and would be very noticeable if noticeable at all. It is show in pictures. I comes with the bolt catch extension (not shown). It will work with a BaD lever as shown in this set up. The BAD lever is not included. I prefer paypal payment and will ship for free. Comes with all mounting hardware. This is the model that allows you to independently release the mag in the ready mag system. $80. Shipped. Might trade for cool items.
