ProMag DPMA2 30-Round .308 Winchester AR-10 Magazine Black Polymer

The ProMag DPMA2 delivers reliable high-capacity feeding for AR-10 platform rifles chambered in .308 Winchester. This 30-round magazine addresses the capacity limitations of standard 10 and 20-round magazines while maintaining the durability needed for extended range sessions and tactical applications.

What Makes This Different

Constructed from DuPont Zytel polymer, the DPMA2 offers superior impact resistance compared to standard polymer magazines. The reinforced feed lips and follower design provide consistent cartridge presentation, reducing feeding malfunctions that plague lower-quality high-capacity magazines. Anti-tilt followers and heat-treated steel springs maintain proper tension through thousands of loading cycles.

Key Features

• 30-round capacity for .308 Winchester/7.62x51mm NATO cartridges
• DuPont Zytel polymer construction resists cracking and environmental stress
• Fits DPMS/SR-25 pattern AR-10 rifles and compatible platforms
• Anti-tilt follower prevents binding and double-feeds
• Heat-treated chrome silicon spring maintains consistent pressure
• Removable floorplate allows disassembly for cleaning
• Witness holes provide approximate round count visibility

Field testing demonstrates reliable cycling across various .308 Winchester loads from 147-grain to 175-grain projectiles. The magazine functions in both semi-automatic precision rifles and designated marksman rifles, handling rapid strings of fire without feeding interruptions. Temperature extremes from -20°F to 140°F show minimal impact on feeding reliability, making it suitable for diverse operational environments.
