Franklin Armory DFM 10rd Magazine 308 Win 7.62x51 NATO AR-15 Black

The Franklin Armory DFM 0051402BLK magazine bridges the gap between AR-15 platform compatibility and full-power rifle cartridge performance. This 10-round magazine enables AR-15 lower receivers to reliably feed .308 Winchester and 7.62x51mm NATO ammunition through Franklin Armory's specialized upper receiver systems.

What Makes This Different

Unlike standard AR-15 magazines designed for intermediate cartridges, the DFM features an enlarged internal geometry specifically engineered for .308-class cartridges. The magazine body maintains AR-15 magwell compatibility while accommodating the increased case diameter and overall length of full-power rifle rounds. This design eliminates the need for proprietary lower receivers while delivering the ballistic performance of larger calibers.

Key Features

• 10-round capacity optimized for .308 Winchester and 7.62x51mm NATO cartridges
• Black anodized aluminum construction with corrosion-resistant finish
• Compatible with standard AR-15 magazine wells and releases
• Reinforced feed lips designed for larger cartridge rim diameters
• Anti-tilt follower system prevents binding during feeding cycles
• Stainless steel spring rated for extended compression cycles
• Floorplate removal tool compatibility for field maintenance

Field testing demonstrates consistent feeding across various .308 Winchester loads from 150-grain to 180-grain projectiles. The magazine functions reliably in tactical scenarios, precision shooting applications, and hunting situations where larger caliber performance is required from an AR-15 platform. The aluminum construction withstands temperature extremes from -20°F to 140°F without feed reliability degradation.
