I picked up ten "New Colt Mags" at a firearms show in Allentown, PA last month, and due to the fact that I was new to the AR scene, I just took the sellers word for it. They appeared new, and I don't doubt that they were, but now I realize that they aren't Colt mags. The price probably should have been a giveaway, 10 for $100, but I didn't know that at the time.
I noticed that the green followers were sticking every time, about halfway down the mag body, so I purchased some of the Gen II Magpul followers. When I tried installing them, I can't even push them through the mag with my hands, so obviously the spring isn't going to be able to do it. They feel twice as heavy as my roommate's surplus mags (steel?), and the powdercoating looks very thick. I'm guessing that this is not allowing enough room for the follower to move up and down properly.
There are absolutely no markings anywhere on the mag or floorplate, and as I've since learned, they therefore cannot be Colt.
Any tips on what to do with them or what they are? I've read that lubricant is a bad idea, and these are tight enough that lube isn't even going to work. I thought about shaving down the followers, but I know from past experience that mags are not something to take a chance on. I'm guessing I just have $100 worth of paperweights.
