This DURAMAG stainless steel magazine is purpose-built for shooters who demand durability without compromise. The 410 stainless steel body won't flex, swell, or warp in extreme heat or cold, and it remains stable through years of storage without the molecular degradation that affects polymer. You can load it up and put it away for extended periods without worrying about feeding reliability when you pull it back out.
The engineering here goes beyond just the material. DURAMAG's Post and Hole construction locks the magazine halves together and then precision-welds the seams, creating a body that's genuinely resistant to structural failure. The LipLock design keeps rounds perfectly aligned in the magazine, so they feed consistently whether you're running standard 55-grain ammo or heavy 300 BLK subsonic loads with 200+ grain projectiles. The Advanced Geometry Follower stays perfectly level throughout the feed cycle, eliminating the tilting that causes double-feeds and jams.
The EverFlex spring technology is caliber and capacity-specific, engineered to maintain tension for the life of the magazine. DURAMAG says you can keep it loaded indefinitely with zero spring degradation. The entire magazine, inside and out, gets the T-360 coating for corrosion resistance and smooth, low-friction operation that makes loading feel buttery smooth. The flat dark earth finish gives you a practical color that works in most field conditions, while the magazine maintains its low-key appearance thanks to the matte black T-360 interior coating.
Yes. The EverFlex spring is designed to maintain tension indefinitely without degradation, and the stainless steel body won't swell or warp like polymer mags. You can safely leave it loaded in storage without concerns about feeding reliability when you pull it back out.
Absolutely. The DURAMAG SS was specifically engineered for heavier 300 BLK loads, including subsonic rounds with long projectiles and high bullet weights. The LipLock feed lips and Advanced Geometry Follower are caliber-specific and handle the different cartridge profiles reliably.
The stainless steel construction is heavier but more durable in extreme conditions and more resistant to corrosion. Stainless is the better choice if you prioritize maximum durability and don't mind the extra weight, while aluminum DURAMAG Speed mags offer a lighter option with excellent reliability at a lower weight cost.
The T-360 coating is applied inside and out and is designed to resist corrosion and maintain smooth operation through extended use. While any coating can show wear marks with hard use, the stainless steel underneath provides inherent corrosion resistance if the coating ever does wear.
