The DuraMag SS .350 Legend magazine is engineered specifically for the .350 Legend cartridge in AR-15 pattern rifles. Built from premium 410 stainless steel with a proprietary T-360 coating applied to both interior and exterior surfaces, this magazine resists corrosion and reduces friction throughout its service life. The T-360 coating bonds at the molecular level and will not wear off like traditional finishes, making it ideal for extended storage or exposure to harsh environmental conditions.
Unlike universal AR magazines, this DuraMag is designed with .350-specific rib geometry inside the magazine body that's critical for reliable feeding and proper round stacking. The follower is marked with ".350" for quick identification, so you know exactly which magazine you're grabbing. This kind of attention to cartridge geometry means fewer feeding problems compared to generic options or modified standard magazines.
The stainless steel body paired with DuraMag's T-360 coating creates a magazine that won't flex or swell like polymer alternatives, even if stored loaded indefinitely. The Advanced Geometry Follower remains level to ensure consistent feeding, while the EverFlex anti-fatigue spring is engineered for long life without performance degradation. The Post and Hole construction locks the two halves together with robotically-welded seams for maximum strength and precision.
DuraMag's LipLock technology keeps rounds secured and properly aligned in the magazine, working together with the .350-specific geometry to deliver the smooth, jam-free feeding you depend on. Multiple user reports confirm that this magazine feeds reliably when used in properly set-up .350 Legend rifles, making it a trusted choice for hunting and range work. The 5-round capacity keeps your overall profile compact while still giving you adequate capacity for field use.
No. The .350 Legend cartridge is larger and has different geometry than 5.56 NATO, so it requires a caliber-specific magazine with a special follower and internal rib design. This DuraMag is engineered exclusively for .350 Legend rifles and won't function in 5.56 NATO firearms. You need a magazine purpose-built for your specific caliber.
Yes, absolutely. One of the key advantages of the stainless steel construction is that it won't flex or swell like polymer magazines do when stored loaded long-term. The T-360 coating protects against corrosion and moisture absorption, and the EverFlex spring is engineered to maintain its strength indefinitely without degradation.
DuraMag's T-360 coating bonds at the molecular level to the stainless steel, which means it won't wear off like traditional painted or anodized finishes. The coating also reduces friction when loading rounds and increases lubricity both inside and out, making the magazine easier to load and cycle. It resists corrosion and helps the magazine shed dirt and dust even when used with dirty ammunition.
Most .350 Legend AR-15s will feed reliably with this DuraMag out of the box. That said, some rifle variants may require minor feed lip adjustments for optimal performance. Many users report flawless function, while a small number have found that slightly modifying the front lip improves feeding consistency with their specific rifle. Check user reviews or contact the manufacturer if you have concerns about your particular rifle platform.
