Does anyone know how to fill a farco .22?

[LegionAir]

Just bought a farco .22 rifle without tank or fill probe. Any solutions on how to fill it up?

Thanks

A buddy of mine recently purchased one of these rifles and converted the fill fitting to a Foster style, (I think),  and now fills it from a standard Co2 tank that is used for carbonation systems.

From what i know the thread is 1/8 npt so a paintball male foster can be screwed in with teflon tape.
