The Colt style AR Mags are Uzi mags with a slot cut in them for the AR mag catch.

I buy cheap Uzi mags and notch them with my mill. No issues.

Brownells sells their own brand mags for the Colt. Less expensive than original and top quality. The problem is you can't have shipped into Maryland.
Oh yeah, though generally the plastic follower ones are easier than the metal follower ones. The metal follower mags are made for the SMG version but Colt often also ships them with the semis.
Also beware of some of the orange plastic follower factory mags and make sure they fit before buying. There was a batch that made it out a few years ago that will not fit the magwell, oversized (ask me how I know).

The only mags that truly suck are the plastic ones

ASC mags are good. They make a ten rounder, too, so you aren't completely mag-less in MD. And I've gotten them at the York, Harrisburg & Gettysburg shows.
The MagLula loader (#: LU16B) works well. Haven't tried the Colt one.

The poly ProMags need a little tweeking to work.
Take it apart. Look at the feed lips. The polys are different as there are feed ramps on the sides. These have flashing that needs to be removed. Take a sharp knife and cut them down. Use a dummy cartridge to check your work. When you have it right, the round will not snag on the flashing and will move smoothly out of the mag.
Also, there will be flashing on the follower. The hold open flange on the follower might need to be sanded down just a bit until it moves freely by gravity up and down in the mag body. I have some 15 of the poly mags and they all work after this treatment.
The ASC mags are good but the springs may not be assembled correctly out of the package. If it doesnt feed, take it down and check.
The Colt and Metalform mags are GTG.
The mag loaders shown work fine. The Maglula is the best and worth the money IMHO. In a pinch, you can put the round on a bench and press the mag over it.

+1 on ASC. Also the Maglula loader is amazing for loading and unloading. just a little lever to flip and drop in the new round.

I buy original Colt mags from High Rock Outfitters. He is an IP here on MDShooters. He has great prices on original Colt mags and any other mags you may be looking for. Great guy to work with.
