The ProMag DPMS LR-308 20-round black magazine delivers reliable feeding and consistent performance for AR-platform rifles chambered in .308 Winchester / 7.62×51mm NATO. Built to strict U.S. manufacturing standards and backed by ProMag's lifetime warranty against manufacturer defects, this magazine is engineered for tactical operators, competitive shooters, and hunters who demand dependable ammunition storage without compromise.
The 20-round capacity strikes a balance between firepower and practical portability—ideal for field operations where magazine weight and pack volume matter. Magazine springs are precision-wound from heat-treated chrome silicon wire, a material standard chosen for its resistance to fatigue and corrosion across extended service cycles. Every stage of assembly undergoes dual verification during manufacturing to maintain consistent feed geometry and follower alignment, critical factors in the DPMS LR-308 platform where tolerance stack-up can affect reliability. The aggressive case hardening and finish resist wear from repeated loading and extraction cycles typical of training and operational use.
This magazine is purpose-built for AR-10 and DPMS LR-308 pattern rifles—weapons systems favored by designated marksmen, precision rifle competitors, and law enforcement who require extended effective range and heavier bullet energy than 5.56 NATO platforms provide. The 20-round format suits both carbine configurations and full-length rifle builds, offering shooters a practical middle ground between maximized capacity and reduced profile for vehicle transport or tactical load-out optimization.
Made and assembled entirely in the USA, the ProMag DPMS LR-308 magazine represents a domestic alternative to imported options, with established distribution and documented longevity across military and civilian shooting communities. For shooters building or maintaining an AR-10 platform, this magazine provides proven feeding reliability without premium pricing.
