Also it doesn't appear to be QC considering the large volume with similar flaws/problems
What the hell is GI SURPLUS with regard to AR mags? Who makes them? Who sells them? Where are they? I have never seen one that I remember. I think the Army buys from a number of difference manufacturers, but I don't know for sure.
If straight mags worked fine (which seems to be the case), why did they come out with curved ones?
Brownells mags are very good too.
Ahem, I believe that Brownells mags are just marked up C-products mags with a different floorplate. I think that C-P also makes re-stamped mags for Midwayusa and maybe others.Brownells mags are very good too.
Rino451, what kind of issues have you had with that latest batch of mags? Was your first batch of mags teflon or marlube coated and the ones you got in the group buy, are they moly coated? If they're really messed up, and the bodies are out of spec, they don't run, etc., then give C-products a call. I believe they replace defective mags, no questions asked. If you could post some pictures, I'd like to see the defects.I bought 11 more recently in a group buy type of thing over on ARFCOM and this batch looks pretty poor. I've yet to really bang on them but they don't compare to my first batch or C-Products mags.
Cporducts no longer makes Brownells mags. Supposedly they are built in house by Brownell.

Don't Waste Your Money
99. All of the other aftermarket crap mags, including USA, Triple K, Western Metal, Victor, Millet, ProMag, RamLine, and Eagle.
40-round mags:
- Sterling of England: These are "combo" mags made for the AR15 and AR18/AR180, so they have both types of mag catch slots. Floorplates are marked "Sterling England". These are the best 40s available, and no coincidence, they are the rarest and most expensive at $150 or so each, if you can find one. These will be private sales.
- PMI/Fed Ord: These mags were originally marketed under the Federal Ordnance name, and later under PMI. A small step below the Sterling mags, but still very good. Expect to pay $50 or more for a like-new mag. These are a bit more common, but still hard to find. While there may be rare exceptions, these will likely also be private sales. Most vendors ran out of these in '98 or early '99 at the latest.
- Everything else (USA/Triple K/Western Metal/Millet) - crap that isn't worth wasting any money on. If a vendor has 40s, they will have these.

The original plastic follower design has a long center post, designed to prevent spring over-compression, and a short anti-tilt leg in the rear. It does not have any anti-tilt leg in the front, which means that the rear of the follower can tilt down and fail to push the rounds up to the feed lips. This results in both bullet-feed misalignments (jams) and in "bolt-over-bullet" fails to feed. The latter is especially common on the last couple of rounds in the mag, when spring pressure on the follower is the lowest. This happens whether or not mags are loaded to capacity or underloaded, and is completely independant of the ammo type used. It is simply a result of poor follower design.
This problem had been an issue with the 30-round mags ever since they had been adopted. In the mid-80s, it was noticed that the problem seemed to happen more frequently with Sanchez-brand magazines, and so an investigation was started to try to determine the cause. It was assumed that the investigation would determine that Sanchez mags were not in-spec. This turned out not to be the case, and the final recommendation was to correct the design of the follower. Thus, new followers with a front anti-tilt leg were created, which used green plastic to make them easy to identify, and were shipped with new Sanchez mags starting in 1988 for field trials. The trial ran through 1990, and proved to be successful at eliminating the feed problems associated with the original followers, resulting in formal adoption of the new design in 1991. All USGI-contract 30-round AR mags were required to have the anti-tilt followers as of late '91. Existing black-follower mags were not upgraded.

You have to decide for yourself how reliable you expect your mags to be. While millions of BF mags exist and have been used, there have been lots of feed problems that are directly attributable to the design of the BFs. GFs are known to significantly reduce or eliminate these problems. Upgrading costs $1.00-1.50 per mag, depending on quanity. Is it worth it? That's a question only you can answer for yourself.
All of my USGI 30s have GFs.
