Includes single stack adapter and HPA adapter only. Designed and tested around CYMA Mid-Cap MP5 mags. Designed to be fitted to the short PP2k gas magazines.


1) Unscrew the three screws in the bottom of the magazine. Remove the gas plate, spring and follower.

2) Insert the single stack adapter into the gas magazine

3) Fit the gasket to the Airtac HPA adapter ( at this stage you can apply a large amount of silicone oil to the gasket to aid insertion. Its a tight fit to ensure good seal )

4) Place the HPA Adapter into the magazine. Screw the screws back in, tightening the rear screw in first, and then the two side screws in small increments. Do not over tighten.

6) Go have fun!
