Used Okay Industries SureFeed E1 30-Round Aluminum AR-15 Magazine – Battle-Proven USGI Classic
Own a genuine piece of American firearm history with this used Okay Industries SureFeed E1 30-round magazine. These are the exact same magazines trusted by U.S. soldiers for decades – the legendary aluminum design that helped define the modern AR-15 platform.
Okay Industries’ story begins all the way back in 1911 as the B. Jahn Manufacturing Company in New Britain, Connecticut. During World War II, they stepped up to support the war effort by producing millions of reliable magazines for the iconic M1 Carbine, supplying American troops with the dependable feeding systems they needed in combat. After the war, the company was renamed Okay Industries in 1968 and continued its legacy of precision metalwork.In 1973, Okay Industries co-developed the original 30-round M16 magazine with the U.S. Military, creating the SureFeed design that quickly became the gold standard. Since then, they’ve produced over 30 million magazines for the M16 and M4 platforms, earning long-term contracts with the Department of Defense and becoming the preferred OEM supplier for Colt and other top manufacturers. These magazines have seen action in every major U.S. conflict for the last 50+ years and are still considered by many to be the most reliable USGI-style aluminum magazines ever made.
This is the classic SureFeed E1 model (the original non-E2 version) featuring:
- Heat-treated 7075 aluminum body with military-spec hardcoat anodizing for maximum durability
- Stainless steel Mil-Spec spring
- Four-way anti-tilt polymer follower that prevents tilting and ensures smooth, consistent feeding
- Reinforced feed lips and spot-welded construction that meets or exceeds every military specification
Every round, every time – that’s the SureFeed promise. These magazines are 100% made in the USA and have passed rigorous government inspection and function testing.This specific magazine is in good used condition with normal cosmetic wear (light scratches, dings, and finish wear from honest range or duty use), but the spring is strong, the follower moves freely, and it feeds perfectly. No dents, no rust, no cracks – fully functional and ready to run. Perfect as a reliable backup mag, training spare, or addition to your collection of true USGI gear.Whether you’re building a period-correct M4 clone, stocking up for the range, or just want the same magazine your favorite rifle manufacturer used for military contracts, this SureFeed E1 delivers unmatched reliability at a fraction of the price of new.Limited supply – grab this piece of American manufacturing history before it’s gone!
