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 black PTFE finish.

While polymer magazines do have their benefits and space age aesthetic, aluminum mags are not to be forgotten about. One of the benefits that aluminum has over polymer is that it does not swell or shatter 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. Now Okay Industries are making their widely popular AR-15 magazines available to the public with the SureFeed and SureFeed E2 designs.

Sure feed E2

Mags work great, and look really cool

A-Ok Magazines in the USGI Tradition


I'm a fan of Magpul, but after a storage mishap I recognized the limits of polymer for magazines. The E2 is an evolution of the tried-and-true USGI design, with a textured exterior and quality internals. It's not as easy to take apart as the Gen 3's, but this is a high quality magazine with an excellent price point for those looking to diversify their collections.

If you think pmags are good, try these

Bought 1 magazine about a year ago to try it. So far, these walk all over pmags. I'm currently replacing all my pmags with these and I wont look back. My rifles cycling even feels smoother just using these. Running subsonic .300 blackout is no problem either, i've had 100% reliability so far.

I purchased 10 of these magazines, very pleased with the quantity, feel and how nicely it seats against a closed bolt fully loaded. Is it better than a D&H or C products mag? Marginally, but not enough to deter me from using them. Okay industries is OK.

Some of the best mags on market

by -

I would say these are some of the best magazines on the market today. Reliably feed, lightweight and made of aluminum. I am partial to the main brand of polymer mags, but every now and again like to throw surplus magazines in the mix and these are far superior to that. Biggest thing is would you trust your life to them since they are generally just range mags? Absolutely work as good as any magazines I have used over the last 30 years.

Great AR mags

Tried a few because of favorable reviews and have not been disappointed

I researched many brands before going with the E2. Very happy with my purchase and plan to buy more soon. As always, Primary Arms service and fast shipping has earned a loyal customer.

They Look Good

by -

I haven't had a chance to function test them yet, but they're certainly the best looking AR-15 magazines I've ever purchased. Hopefully they work as good as they appear.

Quality mags for over 25 years

I have a lot of magazines, but Okay mags have been a dependable favorite for a long time. They work- never cause a problem!
