Gas Stock Adapter, Elite Force/CYMA MP5K

Gas Stock Adapter, Elite Force/CYMA MP5K

Regular price $60

The PolarStar MP5K Gas Stock Adapter is compatible with the Elite Force MP5K (CYMA OEM) but is also able to work with the Tokyo Marui and Galaxy models with only slight modification needed to the gun's receiver. It features internal 1-3/16 - 16 threads to accept the UGS and CGS stocks so you can build a fully contained, HPA/CO2 operated sub-gun for CQB without the need for a remote line.

This can also be used simply as an adapter to mount a standard Milspec buffer tube to your gun if you are using it with a remote line or even as an AEG. It mounts to the receiver using your exiting body pins and does not require modification to the gearbox so it does not interfere with anything. Additionally, this adapter is designed to work with Milspec (Real Steel) receiver end plates so you can configure the gun with your preferred sling plate.


The adapter is machined from a solid block of 6061 aluminum with an anodized finish making it extremely robust and durable. There is also 10-32 set screw incorporated into the design which is tightened against the underside of the buffer tube for anti-rotation thus keeping your stock indexed correctly and rock solid.

  • Compatible with Elite Force/CYMA, Tokyo Marui and Galaxy MP5K models.
  • Compatible with UGS and CGS stocks as well as Milspec Buffer Tubes (1-3/16" - 16).
  • Direct replacement for original end plate without any modification needed so it can be used on AEGs as well.
  • Price includes adapter only. Gun, Buffer Tube, Sling Plate are sold separately.
