Stainless Steel Body:

Our AR-15/M4/M16 Stainless Steel magazines are constructed with the highest levels of quality that guarantees durability and longevity! Our magazines are manufactured 100% start to finish in the USA using “.020” gauge 410 Stainless-Steel Alloy that is heat treated for superior strength, and lasting endurance. Their Stainless-Steel construction means they won’t swell in heat or crack in the cold, making a more reliable alternative to polymer magazines. This is done all while maintaining that undeniably good look. [ref. AMS QQ-P-35].

Available Coatings:

Our durable, wear-in, not wear off, coating (Marlube) was developed directly from our aerospace roots. These Marlube coatings offer supreme performance, protection, and lubricity for your magazine. The more you use it, the better it performs. Our Stainless-Steel AR-15 mags come in two colors, Black Marlube as well as Flat Dark Earth. These Marlube coatings offer supreme performance and protection both to yourself and to your magazine.

Your #1 choice for reliability, durability, and superiority!

    These magazines are well made. I purchase this magazine because it can take the abuse and outlast the ones that came with my rifle.

    High quality

    Posted by Kenneth on Jun 17th 2022

    These magazines are some of the highest quality magazines on the market. I have used everything you can imagine. Everytype of military magazine, Magpul, H&K and ASC mags. The military aluminum mags arnt bad, but I have personally had a few fail at the magazine lips. This is the weak point as all the spring energy is pressing on the bullets that then transfers to the magazine lips. Magpul fails at the lips as well. Magpul will also crack if hit on the side. A guy fell with plate carrier onto rocks and a mag cracked open like brittle plastic. We then had issues with HK mags not feeding, issue was so bad we destroyed all of them in country. ASC mags never had an issue. These are better than $40 HK mags. The quality is second to none. I trusted my life to these mags and they did not disappoint. Do yourself a favor and buy the ASC steel mags and your grand kids will be using them.

    These are exactly what you'd hope to get when you order steel mags. Can't beat the reliability of steel.

    Tan body with orange follower

    Posted by Chris on Feb 18th 2021

    ASC stainless steel mags first came across my attention when I built an AR-10/DPMS 308 I chose them because they allow about.050” inches longer capacity than p mags. So when I built a 20” Heavy barreled AR15 in 223 Wylde I chose ASC 10 rd mags for the same reason. And they work flawlessly. Then I bought some 20 rd tan as with the orange followers. They work flawlessly. I like to keep all my 30 rd mags loaded and ready to go. I thought since I have loaded a lot of ammo to an overall length of 3.010” that I should get some 30 round stainless ASC mags to hold that Ammo and be ready for anything. The reason these mags lose a star from me is because the longer bullets get stuck in the curve of the mag and it gets rounds jammed halfway down the mag where it bends. These mags work fine for my 62gr 556 FMJ plinking rounds that are 2.235” but that makes them average and nothing special for the purpose I wanted to use them for. Maybe if the tool and die maker had built the dies to keep a consistent dimension throughout the full length of the magazine. I’ve yet to shoot them with the 556 plinking rounds but I see no reason why they wouldn’t work with standard Ammo. They look cool but I wish I would have bought a couple more 20 round versions. Just better for my specific ammo

    ASC 5.56 magazines

    Posted by Dennis Fleming on Oct 28th 2020

    I have two ARs, a DPMS and Palmetto Armory. One is 5.56 and the other is 7.62x39. ASC mags are all I use in both and I wouldn't keep buying them if they were junk or didn't function with 100% reliability.
