AGM MP40/Sten/M12S Mid-cap Magazine - 120 BB

The AGM MP40/Sten/M12S mid-cap magazine is a steel magazine designed for AGM MP40, Sten, and M12S airsoft replicas. With a 120 BB capacity, it offers a practical balance between gameplay efficiency and more realistic reload intervals.

The long, slim profile follows the classic WWII-era SMG magazine design. The steel construction provides durability and a solid, realistic weight, making it a good match for historical-style replicas.

As a mid-cap magazine, it requires no winding and produces no BB rattle during movement. The spring-fed system ensures consistent and reliable feeding with minimal maintenance.
