These adapters are made to fit your existing GBBR magazines, and include a single stack adapter, and BB retention mechanism to reduce BB loss during mag changes.

Full support and warranty is offered for these products. They are designed and manufactured by ourselves and our UK manufacturing partner.

Designed and tested with the CYMA MP5 Mid-Caps listed on our website.

Assembly

Installation is dead simple, you’ll need a quick grip vice such as this, a pin punch (2mm), basic screwdriver set and a hammer or mallet.

1) Punch out the bottom pins on the sides of the gas magazine to remove the gas block.

2) Punch out the small pin that retains the follower at the bottom of the gas magazine

3) Insert the single stack adapter into the gas magazine

4) Fit the gasket to the Airtac HPA adapter (at this stage you can apply some silicone oil to the gasket to aid insertion )

5) Place the HPA Adapter into the magazine, and into the clamp. Tighten the clamp until the pin holes line up, and gently hammer them in

6) Go have fun!
