Generation 4 USGI Magazine

[twm134]

Thanks for the info everyone. I'm not concerned at all about feeding m855A1. I just would like a couple of the new magazines with the blue follower for reference in my collection, hence the question about the newer tan okay industries magazines.

Might be a single run, but the Center Industires Tan body, blue follower mags my Battalion got were junk with M855A1. They attempted to minimize the exposed tip hitting too low during during feeding by angling the cartridge up. This raised the tip, but lowered the base of the cartridge. This then results in the the bolt riding over the back of the cartridge and either causing a malfunction or a click when you want a bang. This happened in at least 3-5 weapons that I know of, in one Infantry company. Could be a combination of wear on the M4A1s, but whatever it was, those with PMAGs did not and have not had a problem with feeding. I wrote memorandum on the subject and its made its way to Ft Benning. It was converted into an article on Primary and Secondary if you are interested. https://primaryandsecondary.com/why-...num-usgi-mags/

Thanks for the informative link. No internet hearsay. Straight from the user's perspective.

Well written memo/article. Thank you for sharing.

Ditto.

The feed lips have been modified to perform better with M855A1, as far as I can tell by just unscientifically holding them next to each other, the new mags feed lips start slightly to the rear of the previous version, but retain the same geometry. I assume this is to allow the round to have a more upward tilt as it enters the chamber. Our unit received a few boxes of them when we were fielded the M4A1.

Magpul PMAGs already on the market with an NSN, and now manufactured in Tan 499 no less, performed flawlessly with the M855A1 EPR in testing, but that's neither here nor there...

Gray is the new geometry.

I simply cannot stand the thought of that hardened tip of M855A1 touching any part of my gun or magazine.

I don't trust it yet.

It's completely insane to build a mag around a problematic round. Off topic observation.

As I also suspected, just wanted clarification.

Not answering for Stick, but the ones in the wild appear to have latest gen Magpul enhanced self-leveling foliage green followers.

Scroll through, they have multiple pics of the Okay / Surefeed Desert Tan thirty round USGIs.

They tried their best to copy the Magpul M3 design but seems that they're having trouble. Should have just adopted magpul..

Does that Surefeed magazine have a blue follower?

I contacted Surefeed, and these are not the same, or intended to be substitutes for the latest USGI civilian bonus award magazines.

I will point out Surefeed did not use the above terminology, that is a semi serious comment showing my disgust in civilians getting awards and bonuses for spending taxpayer money to duplicate a COTS item.
