USGI M4/M16 30-round gray aluminum magazine from Okay Industries

standard USGI magazines.  Manufactured by Okay Industries, 2019 / 2020 new Surefeed.

Okay Industries is a trusted brand, and has been a big supplier to the LE community and shooting enthusiasts for decades.  Charlie's has seen 2019 and 2020 dated and branded Okay Industries and are standard gray aluminum coating with scratches through the gray dry-lube coating, which is pretty standard for any new USGI mag.

Okay makes the original USGI mags for Colt, LMT and Rock River and other brands.  Okay now makes the SureFeed magazines in the civilian market, but there are two varieties of Surefeed magazines, to make it really hard on the buyer.  Most Surefeed commercial magazines have a dotted texture and are very handsome in design.  This is not that handsome design.  This is a standard USGI magazine, and most would say that it looks like each magazine has been thrown in a bin, just to get some wear on, so expect wear, even though these come to us in sealed plastic bags.

30 round mags from Okay industires.

The aluminum magazines are preferred by soldiers in various areas of the U.S. Military. The stainless-steel spring provides proper tension and keeps rounds properly aligned for optimal function. These USGI magazines are all hardcoat anodized and this model features a Grey dry-lube finish. Okay / MHMTG magazines are put through a multi-step inspection and testing process to ensure they live up to the performance standards that people have come to know with Okay Industries.

Polymer magazines do have their benefits and space age aesthetic, aluminum mags are a 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 MHTG was the civilian version / brand.  Charlies also sells the older MHMGT magazines here.  From what we can tell, they look identical, except for different markings.
