Promag FN Scar 17 .308 Rifle Magazine Black Polymer 50/rd

The Promag FN SCAR 17 .308 Rifle Magazine in black polymer is a 50-round drum designed specifically for the FN SCAR 17 platform and other .308 Winchester/7.62×51 NATO compatible rifles. This high-capacity drum magazine extends the operational range between reloads, making it an asset for training cycles, tactical operations, and sustained fire scenarios where magazine changes would otherwise interrupt continuity.

The 50-round capacity represents a significant increase over standard 20-round box magazines, reducing the frequency of manual reloads during extended range sessions or field exercises. Polymer construction keeps weight manageable—at 3.08 pounds when loaded, it remains practical for mounted or prone shooting positions. The geometry is engineered to function reliably in the SCAR 17's magazine well without excessive friction or binding, critical for weapons that see hard use. Promag's proven track record with AR-platform drums translates to consistent spring tension and feed reliability across various ammunition types and environmental conditions.

This magazine serves precision rifle competitors, law enforcement marksmen rotating through qualification sequences, military unit armories, and dedicated shooters who prioritize reduced reload cycles during intensive training. The 50-round capacity is particularly valuable for long-range precision drills where shooter focus on accuracy is disrupted by frequent magazine changes. The SCAR 17 platform's adoption across professional units has created strong demand for high-capacity magazines that maintain point-of-aim consistency.

In the .308 rifle magazine segment, drum configurations are less common than in 5.56 or 9mm platforms, making FN SCAR 17-specific options limited. The Promag DRM-A41 fills that niche by offering shooters who invest in the SCAR platform access to the same extended-capacity advantages available to AR-10 and other 7.62×51 users. Compatibility should always be verified with your specific rifle variant before purchase.
