Mid-cap Magazine 120 BB - MP40/Sten/M12S AGM is a steel magazine designed for historical SMG replicas, combining a classic form with practical capacity.

Construction and design

The body replicates the form of magazines used in platforms such as the MP40 and Sten. The simple, elongated profile follows WWII-era designs and allows proper guidance in the magwell.

Build

The housing is made of steel. The material provides resistance to mechanical damage and wear during use. The construction maintains realistic weight and handling, which is important for historical replicas.

Function

This mid-cap magazine operates without winding and without BB rattle. The spring-driven system supports reliable BB feeding and consistent operation. The 120 BB capacity reduces reload frequency while maintaining the character of the platform.

Historical background

This type of magazine originates from designs used in the MP38/MP40, featuring a double-stack to single-feed configuration. The solution was later adopted in designs such as the British Sten due to simplified production and wartime requirements. Similar magazine forms became standard across many 9 mm SMG platforms, including the M12S.

Compatibility

For replicas:

Intended use

For historical SMG replicas and reenactment setups. Suitable where visual authenticity and predictable magazine performance are important.
