This item is for installing M4 series stock on the electric compact machine gun MP7A1.
As "stock base set" is a set of stock ring and stock pipe, M4 stock can be installed soon after installation.
We adopt reinforced resin mixed with glass fiber as material of "stock base" and balance strength with lightness.
The design with the duct shape as an accent matches the MP4A1 M4 stock without a sense of discomfort!
You can customize it to the unique MP7A1 looks according to your preference.
