The Promag FN SCAR 17 .308 20-round polymer magazine brings reliable, durable ammunition storage to one of the most capable battle rifles in civilian hands. Built from a proprietary DuPont Zytel-based polymer, this magazine is engineered to handle the demands of the 7.62x51mm/.308 cartridge without compromise. Whether you're running carbine drills at the range, preparing for a precision rifle course, or maintaining a fighting rifle for serious use, a 20-round capacity strikes the balance between firepower and practical handling that SCAR operators know matters.

ProMag combines time-tested manufacturing methods with modern materials science here. The magazine body uses injection-molded mil-spec polymer compounds for durability and consistency. The follower is injection molded for reliable round feeding, while the magazine spring is formed from heat-treated chrome silicon wire—the same material choice you'll find in quality magazines across the industry. That engineering philosophy means the magazine feeds reliably and handles hard use without premature wear.

The flat dark earth finish matches the factory SCAR 17 aesthetic and blends naturally into a tactical or professional kit. Made in the USA and backed by a lifetime guarantee against manufacturer's defects, this magazine is designed to outlast the ammunition you feed through it. If you run an FN SCAR 17 and want a proven spare or upgrade from factory magazines, this is the kind of no-nonsense gear that earns trust in the field.
