Built for serious AR-15 shooters who demand uncompromising reliability, the DURAMAG SS 5.56/.300 BLK 30-Round Magazine in Flat Dark Earth (FDE) delivers a premium stainless steel feeding solution that outperforms polymer alternatives in durability, consistency, and longevity.

Constructed from 410 Stainless Steel, this magazine resists flexing, swelling, and deformation even under the most demanding conditions. The proprietary T-360 total coating technology covers the magazine inside and out, ensuring smooth chambering, effortless loading, and superior corrosion resistance through extended field use or long-term storage — fully loaded, no additives required.

Key Features:
• LipLock Technology – Keeps rounds secured and properly aligned for consistent presentation
• Advanced Geometry Follower – Maintains level orientation for reliable, jam-free feeding
• T-360 Total Coating – Full interior and exterior protection for smooth performance and product longevity
• EverFlex Anti-Fatigue Spring – Engineered for long service life and sustained feeding reliability
• Post & Hole Construction – Robotically welded for added strength and dimensional precision
• 410 Stainless Steel Body – Will not flex or swell like polymer; safe for loaded storage without modifications

Especially well-suited for .300 Blackout shooters running rounds with long overall length (OAL) or heavy subsonic loads, the DURAMAG SS handles the geometry challenges that trip up lesser magazines. Whether you’re training, competing, or running a precision suppressed build, this is the magazine that keeps up.
