The Promag AR-10 .308 Win FDE polymer magazine is a reliable, domestically made feed solution for AR-platform rifles chambered in .308 Winchester. Built from injection-molded Dupont Zytel polymer, this 20-round magazine delivers the durability and consistency you need at the range or in the field, without the weight or corrosion concerns of steel. Whether you're running a DPMS LR-308 or SR-25 pattern rifle, this FDE (Flat Dark Earth) mag integrates seamlessly into a modern tactical or hunting setup and keeps your ammo ready to go.
ProMag's approach to magazine manufacturing emphasizes precision from the ground up. The magazine spring is formed from heat-treated chrome silicon wire—the same material specs you'll find in premium mil-spec designs—and every unit passes quality inspection during assembly. That attention to detail translates to reliable feeding, minimal wear on your magazine catch, and a product built to last. The polymer construction is lighter than steel, resists corrosion, and won't rust or degrade in harsh conditions, making it ideal for hunters and shooters who demand gear that works first time, every time.
This magazine is engineered specifically for LR-308 (DPMS) and SR-25 pattern magazines and will not fit Armalite pattern AR-10 rifles, so confirm your rifle's magazine platform before purchase. Backed by ProMag's lifetime warranty against manufacturer defects and proudly made in the USA, you're investing in a magazine that's as committed to reliability as you are to your shooting.
