Converting a crosman ratty 2250 AirSource to single co2

[Shed tuner]

I seem to have come into possession of the above gun. Needs a reseal, but I've quickly realised that whilst I like the metal breach, I prefer just a regular 12g CO2 cart for the occasional use the kids will have with it.

Seems to me that all I need to switch back is a regular valve with piercing pin, and the end cap with the short extension ? I know there are minor stock changes, but that's just cosmetics. Am I right, or am I missing something ? Does the valve port hole in the side of the cylinder cause a sealing problem ? I doubt it as the cylinder itself is not pressurised - the co2 cart just seals against the valve face...?

Thanks in advance,

JB

..or I could get a convertor for £12 from Taiwan fleabay..

kings are always in demand even though they can be leaky blighters and some can be a pita to seal
rather than alter yours sell it/trade it for an xl or a 2250 of similar spec
if you do want to convert it you need
2250 co2 cap or add a rod to yours
2250 main tube with breech screw tapped to suit the king or live with a hole in the side of the tube
std 22xx rear tube cap
2250 valve or just swap the front on the king one to a std 2250- one
that's all that needs swapping

thanks ped... good to know it's just the front half of the valve that's different too...

The rest is as expected, so that's cool...

Just repaired a Umarex Winchester rifle that takes the 88grm CO2 cylinder. The owner had bought a Walther 2x12 grm converter for it. I was very impressed with quality of this converter, you can use either one or two 12grm capsules, and of course you can unscrew it at any stage without losing any remaining gas.
