The ProMag FN FAL .308 Winchester 20-round polymer magazine delivers reliable feeding for your FN FAL in a lightweight, durable package. Built using a hybrid construction method that combines traditional steel stamping and welding with modern injection molding, this magazine brings together time-tested metallurgy and precision polymer engineering. If you run an FN FAL for hunting, competition, or designated marksman work, a quality spare magazine—especially one engineered for the .308 Winchester cartridge—is part of sensible rifle setup.

ProMag has engineered this 20-round magazine with a polymer body that doesn't add unnecessary weight to a rifle that may already see hard use in the field. The design incorporates a steel internal insert running the full length of the magazine tower, stamped and welded to match factory magazine geometry and reliability standards. The follower is injection molded, and the spring is heat-treated stainless steel—materials chosen to withstand repeated loading cycles and the kind of use patterns real shooters demand.

Made in the USA, this magazine is backed by a lifetime guarantee against manufacturer defects. That warranty reflects confidence in the materials and processes: mil-spec polymer compounds paired with quality steel components means you're not buying a throwaway part. Whether you're building out a spare magazine kit for range days or keeping a backup loaded and ready, the ProMag FN FAL .308 is designed to feed when it matters.
