Okay Industries, 30 round magazine MHMTG brand magazine

standard USGI magazines. Manufactured by Okay Industries, under the brand name NHMTG

Okay Industries is a trusted brand, and has been a big supplier to the LE community and shooting enthusiasts for decades. The first batch are dated 2014 and are standard gray aluminum coating with scratches through the gray dry-lube coating, which is pretty standard for any new USGI mag.

The magazines are upgraded with green Magpul "enhanced self-leveling followers," specifically made for USGI 30 round magazines. The Magpul followers feature a 4-way anti-tilt design for increased feeding reliability, and are made "a non-hygroscopic and self-lubricating polymer."

NHMTG was the civilian brand for Okay Industries and are hard to find.

As crazy as it might sound, collectors have been known to hunt long and hard for NHMTG. Okay makes the original USGI mags for Colt, LMT, and Rock River and other brands. Charlie's also sells the newer Okay Industries USGI mags, which look and feel pretty identical, but are 2019, 2020 or later vintage, and you can see that here

The NHMTG brand was shutdown, and are a bit more expensive, and from we have been able to tell, relatively hard for distributors and dealers to keep in stock. The yellow followers are generally in the 2012-2014 vintage

Polymer magazines do have their benefits and space age aesthetic, aluminum mags are are classic, and still work great. One of the benefits that aluminum has over polymer is that it does not swell in extremely high or low temperatures. The aluminum feed lips are also strong enough to withstand the pressure of a fully loaded magazine over long periods of time without bending or breaking.

The history of Okay Industries goes back to WWII where they helped manufacture millions of M1 Carbine magazines for the United States Military. Fast-forward and they helped co-develop the 30-Round M16 magazine and has been a preferred supplier of magazines to the U.S. government ever since. Okay now is making their widely popular AR-15 magazines available to the public with the SureFeed designs, but before Surefeed, the NHMTG was the civilian version/brand.
