Got my 3 in the mail today, and They are nearly Identical to the Factory Saiga mag, except for the floorplate. The Floorplate looks like teh plates that tromix made to cut down 10 Rd. AGP mags, But I have not handled one (tromix) in person, so I cannot say. No live fire yet, but they lock in place tight. I'll post a few pictures of the floorplate tonite.
