Specna Arms MP40 / Sten / M12S Mid-Cap Magazine - 120 BBs

The Specna Arms MP40 / Sten / M12S Mid-Cap Magazine is a durable 120-round steel magazine designed for Specna Arms and AGM MP40, Sten and M12S electric airsoft replicas.

Its long, slim profile faithfully follows the design of the original WWII-era submachine gun magazines. The steel outer shell provides excellent durability, realistic weight and an authentic feel, while polymer components are used where required to ensure reliable feeding and smooth operation.

Thanks to its Mid-Cap design, the magazine does not require winding and eliminates the rattling noise commonly associated with Hi-Cap magazines. The spring-fed mechanism delivers consistent BB feeding, making it an excellent choice for both skirmish use and historical airsoft loadouts. With a capacity of 120 BBs, it offers a balanced combination of realism and practical ammunition capacity.
