5KU 1913 Stock Adapter For CYMA Airsoft MP5 Black

5KU 1913 Stock Adapter For CYMA Airsoft MP5

The 5KU 1913 Stock Adapter for CYMA MP5 is a precision-machined upgrade designed to give compatible MP5 AEG airsoft replicas a modern M1913 / 20mm Picatinny rear stock interface. Ideal for custom builds, the adapter opens up a much wider choice of compatible folding and rail-mounted stock systems while maintaining a compact, clean appearance.

Manufactured from CNC-machined aluminium, the adapter combines strength with a lightweight construction.

A durable black anodised finish provides additional surface protection while complementing the original styling of the MP5 platform.

M1913 Stock Interface

Once installed, the adapter provides a vertical M1913 Picatinny rail, allowing compatible rail-mounted stock systems and folding mechanisms to be fitted to the rear of the airsoft replica.
