When outfitting an FN SCAR 17 for reliable duty use or extended range sessions, magazine choice matters. A magazine that balances durability, consistent feeding, and a reasonable price reduces malfunctions and stretches training budgets without sacrificing performance.
PROMAG FN SCAR 17 is a 20-round replacement magazine designed specifically for the Scar 17 and Scar Heavy models. Constructed from Technapolymer — an advanced proprietary formula of carbon fiber glass fill and polymer — this mag is built to resist impact, abrasion, and the heat of sustained use. 
Construction and Materials
The Technapolymer body provides a tough, lightweight chassis that won’t dent like metal alternatives and resists environmental wear. Internally, the magazine uses a heat-treated chrome and silicone spring engineered for extended reliability and a lower spring fatigue rate. Those features translate to consistent bolt lift and feeding over thousands of rounds, which is essential for duty and training use.

Fit, Function, and Field Use
Because it’s specified for Scar 17 and Scar Heavy models, the PROMAG FN SCAR 17 delivers a factory-like fit that reduces stovepipes and misfeeds when paired with a properly maintained rifle. The 20-round capacity strikes a balance between compliance in areas with limits and keeping weight manageable for patrol or competition carry. At a price of $21.99, it’s an economical spare-mag option for multi-mag rigs or range rotation. Shop this product and review compatibility before adding to your loadout.
Reliability Considerations
Heat-treated chrome and silicone springs resist corrosion while maintaining spring tension longer than untreated coils. Combined with the reinforced polymer body, this design reduces the common wear points that produce failures in older magazines. Routine inspection and cleaning remain important, but the PROMAG FN SCAR 17 is built to stand up to hard use.
