hey guys, i'm hoping one of you can help me ID these 3 20rd mags i've had buried away for years upon years. these were given to me probably 8 years ago, and at the time i didn't have an AR, but based off of the shape and size, I assumed they were for an AR. about 5 years ago I joined the AR-club, and sure enough they don't fit. I've since assumed they were mini-14 mags, but I don't have one to test and confirm, and none of my friends have one either. the thing is, when I google for images of mini-14 mags, I haven't seen any with the same receiver-catch (or whatever its called), so i'm a little stumped. there are no markings on these mags; nothing on the sides or floorplate. they accept .223 rounds, and came fully loaded with some ancient rounds, 19-20 per mag. these are the mags. thanks for the help!
