Center Industries is an OEM supplier.

They have been supplying for quite sometime. I have a lot of them in the original wrap dated 92, 99, 03, 09, 11, and 12.

The Colt is not issue per say. I believe they were made for them by whatever company held the GI contract at the time. Some think they are higher quality but they are not. Very very early Colt mags are collectible to some, but not the vast majority.

You do have two good quality mags.
