I recently acquired some 20 round and 30 round mags. Two of the 20's have a colt follower with pransing pony or whatever it is called and the body has a I over U stamped on the back. Are these original bodies? The follows apear to be made of aluminum. on all the 20's.

The 30s both have Adventureline floorplates and have most of their finish with black followers.

Are these USGI mags?

Troy will have a more definitive answer, but yes, those are USGI mags. The "UI" stamp is for Universal Industries, who made (makes?) Colt's mags. Sounds like someone may have changed the floorplates, which is inconsequential. In the military, mags are often disassembled in big lots, cleaned, then assembled with whatever parts are grabbed out of the box. The 20's w/alloy followers should function flawlessly. You may want to replace the black followeres with green ones from ComputerGuy in the EE.

Thanks for the info. I bought all 6 mags for $75, so it sounds like I did okay. I will replace the two black followers in the 30's with the green follower. Thanks again!

I believe the "UI" is "CI" which stands for Colt Industries.

The UI stands for Universal Industries, however, if you turn the magazine sideways it says CH, which means Colt Hartford. I took notes, too. [:D]
