The ProMag DPMA4 40-round .308 Win detachable magazine for AR-10 rifles is built for shooters who want to spend more time at the range and less time fumbling with reloads. Standard AR .308 magazines max out at 10 or 20 rounds, which gets old fast when you're running drills or putting rounds downrange. This polymer magazine delivers that expanded capacity without the bulk, fitting DPMS and SR-25 pattern rifles reliably and securely.
Construction matters with magazines. The DPMA4 is molded from DuPont Zytel polymer—a material engineered for durability and consistent performance through thousands of cycles. The feeding system relies on a heat-treated chrome-silicon wire spring that maintains constant pressure, ensuring smooth, reliable rounds whether you're loading one or filling it to capacity. It's the kind of engineering that keeps your rifle running when it counts.
Made in the USA and finished in black, this magazine is a straightforward, no-nonsense choice for AR-10 shooters who want factory-standard compatibility without the premium price of proprietary designs. Whether you're building a 308 rifle platform for long-range precision, competition shooting, or general duty, the 40-round capacity gives you the flexibility to shoot the way you want to shoot.
