Promag Springfield Armory M1A / M14 Magazine .308 cal Black Polymer Drum 50/rd

The Promag Springfield Armory M1A / M14 Magazine .308 cal Black Polymer Drum 50/rd delivers significantly extended firepower for precision rifle platforms built on the venerable M1A and M14 action. Purpose-designed for shooters and tactical operators who demand high-capacity ammunition storage without the weight penalty of steel magazines, this polymer drum magazine addresses a critical gap in extended-range engagements where reload frequency directly impacts tactical effectiveness. Whether deployed for designated marksman roles, competition shooting, or field operations, the 50-round capacity transforms your M1A into a sustained-fire platform.

Constructed from reinforced black polymer, the Promag DRM-A2 drum utilizes a precision-wound spring and follower system engineered to maintain consistent feeding pressure across all 50 rounds of .308 Winchester ammunition. The drum's compact footprint—measuring 8.5 x 4.5 x 12.8 inches and weighing just 3.16 pounds when empty—balances capacity against ergonomic handling and balance point management that field-proven shooters require. Internal geometry is optimized for the M1A's feed system, ensuring reliable chambering without the double-feeds or stoppages that plague poorly-designed high-capacity alternatives.

This magazine excels for M1A and M14 rifle owners conducting extended training sessions, competition formats with unlimited ammunition stages, or tactical scenarios where suppressive fire capability justifies the added weight. The polymer construction resists corrosion and environmental degradation in harsh climates, making it suitable for field storage without protective casings. Compatibility is universal across all standard M1A platforms and military M14 variants using standard .308 Winchester or 7.62×51mm NATO ammunition.
