OKAY OKAY 30-Round Surefeed Legacy AR/M4 USGI Magazine

The Okay Industries SureFeed magazines offer many advantages over the standard aluminum AR-15 magazines.

With over 40 years of battle tested use, these aluminum magazines are preferred by soldiers in various areas of the U.S. Military. Featuring a four-way, anti-tilt, self-lubricating follower, you can rely on this 5.56 magazine to feed correctly without any issue no matter the condition. 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 gray dry-film lube or tan finish. Every SureFeed magazine is 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.

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 32-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.

    Fast shipping is an understatement. The surefeed mags speak for themselves, but the customer support provided by rooftop is second to none and funny!!! Thank you for the ramen in these tough times.

    Would recommend 10/10

    Worked well as expected had a couple failure to feed issues but ended up being the ammo(igman) not the mags. Great lightweight product that performs just as well as a pmags do but they’re several ounces lighter, pack better, cost less and are far more durable. Rooftop also sends you a complimentary dinner for one so what do you got to lose? Buy em before they ban em!

    Fast shipping is an understatement. The mags speak for themselves, but the customer support provided by rooftop is second to none.
