Hi All,

I've just purchased a Crosman 2240 pistol from a member here. When it arrives in the next couple of days, I will be looking into bulk-filling the CO2 rather than using the (expensive) crosman powerlets.

Has anyone here had any experience with this?

I have seen that the filler cap can be switched out for one with a threaded valve in it?

I'm thinking of using either a sodastream canister or a CO2 fire extinguisher for my source of bulk CO2.

If this is possible, would anyone be able to help me out with choosing the right fixings and tubes etc to pass the CO2 in the canister to the action tube of the pistol?

My knowledge of CO2 bulk-filling is very limited as you can see, so I hope someone will be able to offer some advice.

Best Regards
