Hpa Connector and Hose Advice

[BigStew]

HPA people need some advice I am wanting to fit a golden eagle AOW into a pulse rifle. I have already stripped the gun down and it will fit. I have found a threaded 12g refillable CO2 bulb to use as a gas tank. So need advice on on what hose, connections I need? I assume I going to need a threaded connector to the shot gun any particular brand to use?

I fitted a jag arms (secutor) valve to mine. That was fitted through the original valve in the grip after drilling a bigger hole in the grip.

I now use a mancraft co2 adapter with a regulator attached to feed the shotgun (saves carrying a bigger bottle!)
