Description

These vintage double-column magazines hold up to 30 rounds and are known for their extreme reliability. While originally built for the M3 submachine gun, they are also highly compatible with certain open-bolt firearms and pistol caliber carbines, such as the MAC-10 and UZI conversions.


Condition report:

The magazines exhibit a dark blued finish showing moderate to heavy military use, characterized by surface wear, thinning of the bluing on high points, and numerous scattered scratches and dings. Some minor surface oxidation and light pitting are present, primarily near the base plates and on the reinforcement collars. The feed lips are intact and do not appear deformed or cracked. The springs retain significant tension, and the followers move freely within the magazine bodies. Overall, the condition is consistent with authentic World War II-era field use.
