ProMag magazines are designed utilizing both traditional stamped steel and modern precision injection molding of polymer compounds. This hybrid M1 Carbine drum utilizes both with a polymer lower body and stamped steel upper insert to keep it lightweight while retaining the strength and support where it's needed. While standard M1 magazines come in 15 or 30 rounds, the innovative drum from ProMag nearly doubles that by increasing capacity to 50 rounds of .30 Carbine. Internally it is assembled with a heat treated stainless steel spring and injection molded follower to ensure it functions reliably with a long service life. This American made M1 Carbine drum will turn that old warhorse into a range favorite. ProMag also backs every magazine with a lifetime warranty against manufacturer defects.
