The ProMag CAR01 is a 10-round detachable magazine built for the U.S. M1 Carbine in .30 caliber. If you're running an M1 Carbine—whether you're out hunting, at the range, or maintaining a classic mil-spec rifle—reliable magazines are non-negotiable. This blued steel magazine delivers the capacity and durability you need without the fuss, and it's designed and built right here in the USA.

What sets ProMag apart is their commitment to the mechanics that matter. The magazine spring is precision wound from heat-treated chrome silicon wire, which resists fatigue and maintains consistent feeding pressure through heavy use. Every stage of assembly gets checked and double-checked to ensure you're getting the same quality control on your tenth magazine as your first. That's not marketing talk—that's the difference between a magazine that runs and one that becomes a point of failure in the field.

The rugged construction and straightforward design make loading and unloading quick and intuitive. This isn't a magazine that demands finesse; it's built to handle the realities of hunting season and repetitive range days. And because ProMag backs their magazines with a lifetime guarantee against manufacturer defects, you can trust that your investment is protected.
