Designed for the CO2 20oz, nitro or HPA player. The player that needs the big drop for the big tank. It moves your tank 5 1/2 inches forward and 2.5 inches down. It also includes an ASA with a hole for a gauge if you need it. (The hole is plugged when you get it. You can either leave the plug in, or remove the plug to install a gauge.) It has holes drilled to mount on standard OR Spyder bottomlines. Will work with all CO2 tanks and screw-in nitrogen tanks
This design has the On/Off valve with degassing feature. As you loosen the knob it will empty your gun (but not your tank) of air so that you can unscrew your tank and not have to worry about residual trapped air or pulling the trigger to rid your gun of the air. No more torn up tank o-rings.
