When you step up to a stainless steel magazine, you're making a commitment to durability and longevity. The DuraMag SS 20-round delivers both in spades. Constructed from heat-treated 410 stainless steel, it won't flex, swell, or degrade the way polymer can, especially when stored fully loaded for extended periods. That solid construction pairs with a finish that actually means something: DuraMag's T-360 total coating bonds at the molecular level and covers both interior and exterior surfaces to resist corrosion and reduce friction when you're loading rounds.
This magazine uses several innovations that most competitors skip. The proprietary LipLock design keeps your rounds perfectly aligned and prevents binding, while the Advanced Geometry Follower stays level throughout the magazine instead of tipping like older designs. That matters when you're feeding anything from standard 55-grain ammo to heavier 300 Blackout subsonic loads. The EverFlex anti-fatigue spring is calibrated specifically for this capacity, maintaining consistent tension indefinitely without bottoming out or losing spring rate from years of use.
The post-and-hole body construction, robotically welded at the seams, creates a magazine that simply won't crack or develop reliability issues from normal use. Real-world testing shows these mags handling drop tests, concrete impacts, and extended competitions without performance degradation.
Twenty rounds strikes a balance many find perfect for bench shooting, prone positions, or when you want a lower-profile option without sacrificing reliability. The orange anti-tilt follower provides instant visual feedback on mag status and stacks rounds consistently. Compatible with .223 Remington, 5.56 NATO, and .300 Blackout in the same magazine body, so switching between loads doesn't require different hardware. The finish is slick enough that seating and ejecting from your magwell feels smooth every time, with or without gloves.
Yes. Unlike polymer magazines that can swell or degrade over time, the stainless steel DuraMag SS is safe for extended storage while fully loaded. The EverFlex spring maintains consistent tension indefinitely without losing spring rate, and the rigid body won't flex or deform from long-term static pressure.
Yes. The internal geometry is optimized to feed .223 Rem, 5.56 NATO, and .300 Blackout reliably from the same magazine body. The anti-tilt follower and LipLock design accommodate the different cartridge profiles without any modifications needed.
DuraMag's T-360 coating bonds at the molecular level to both the interior and exterior surfaces, so it won't wear off like paint or typical coatings. It reduces friction for smoother loading and seating, increases corrosion resistance, and helps the magazine resist dirt and dust accumulation even with dirty ammunition.
Stainless steel offers superior rigidity and won't flex, swell, or crack under sustained use like polymer can. It's heavier than aluminum, but the trade-off is exceptional durability for long-term storage and use in extreme temperatures. The DuraMag SS is designed specifically for shooters who prioritize reliability and longevity over lightweight convenience.
