Promag Spgfld M1a 308win 20rd Bl

The ProMag Springfield M1A 308 Winchester 20-round magazine is a precision-engineered feeding system purpose-built for the M1A platform and other .308 Winchester rifles that accept double-stack detachable magazines. This magazine delivers reliable round-count capacity in a format optimized for operators, competitive shooters, and precision rifle enthusiasts who demand consistent performance across high-round-count training sessions and field operations.

Steel construction throughout provides dimensional stability and resists deformation under the pressures generated by .308 Winchester ammunition. The magazine's springs are precision wound from heat-treated chrome silicon wire, a material specification that ensures consistent feeding cycles across thousands of rounds without creep or spring-rate degradation. Every magazine undergoes rigorous assembly verification to maintain uniformity in feed lips, follower geometry, and spring tension—critical variables that determine zero-failure feeding reliability in semi-automatic rifle systems.

The 20-round capacity strikes a balance between loadout weight and practical magazine rotation during extended range sessions. For M1A platform users, this capacity integrates seamlessly with standard loading techniques and stacks predictably in magazine pouches and retention systems. The ProMag Springfield M1A .308 magazine is manufactured and assembled in the USA and backed by a lifetime warranty against manufacturer defects—a commitment that reflects confidence in material selection and production control.

Suitable for M1A rifles, M25 rifles, and compatible platform systems, this .308 Winchester magazine serves competitive shooters, precision rifle competitors, and tactical training environments where feeding reliability is non-negotiable. Purchase multiple magazines for load-rotation discipline, allowing inspection and maintenance cycles between use.
