My friend gave me this pistol. I know it’s a 2240 crossman and has a BNM parts, but I’m not sure about the pcp conversion. He told me he bought the gun online from a website built like this. Any idea as to what kit this is? I don’t want to overfill the tank. 
Pistol ID?

Looks like it uses one of the Benjamin magazines. The air tube has a HIPAC high pressure air adapter rated for about 2000 psi. If the valve in the 2240 base pistol is not pinned, be very careful if you try to fill the gun with air.

I would tap the valve retention hole in the valve to the size of the Disco valve retention screw, 6-32 maybe? Plus, if not done already, use a Disco valve stem-

Thanks for the replies. I'm going to have one of my friends check it out before I do anything. Gotta try find the website where he got it from.
How do I convert it back to a CO2 canister?

You'll need to make sure the gun has no air or co2, then you'll need the 2240 end cap at the very least. See if adding the end cap is enough to pierce the cart. If not, would suspect the piercing pin/valve stem has been replaced with a Disco valve stem. If so, either replace, or acquire a bulk fill set up.

Adding the end cap on a 2240 will not pierce the CO2 cartridge. On the 2240, if the valve has not been changed to a Discovery valve or modified 2240 valve, the co2 cartridge is pierced the first time the hammer is cocked and dry fired. The first dry fire should then pierce the cartridge. If the valve has been changed to a Discovery valve, you will have to change it back to a 2240 valve or get the proper charging adapter and use co2 in the HIPAC adapter. The 2240 valve does not have to be pinned if you only use co2. An unmodified 2240 valve will have a piercing pin in the valve attached to the exhaust (poppet) valve. You can see the piercing pin in an unmodified valve by shining a light into the tube. It will be pointed in the center of the valve end. Make sure there is no air or co2 in the gun before removing the HIPAC. Do this by dry firing the gun making sure. There will only be a dull thud if there is no co2 or air present. If you hear a pop, keep dry firing until you hear only the thud.

Stevev,
I think we are dealing with a newcomer to our hobby and probably not ready to tackle mods to the gun and disassembly and reassembly. We all started out that way and try to help a newcomer any way we can. With the HIPAC, we certainly don't want him to make a mistake with high pressure air.

Jonah - you need to re-read my response. I am fully aware of how things work re: the 22XX format - if his valve hasn't been altered, all he has to do is add the 2240 muzzle end cap (after safely removing the hipac) and ad a co2 cart. Again, if the valve still possesses the piercing pin, everything should work as designed. Not sure why you have issues with my response. RE READ if necessary.

Looks like a hipac. Be careful. Theres this dude who modified his same gun to pcp with the hipac and it blew up cause the tube wasnt strong enough and shot the valve right into his legs. Ouch.

I just checked it looks like the co2 piercer is still inside. Im going to order a co2 cap and some cartridges to see if it works. Thank you for all your help. Not to sure if the Hipac still works, anyone want it? I'll send it to you if you pay for shipping.

EDIT: Not the video I thought it was. One thing I don't understand though - notice the valve - it's a Discovery valve - but it still has the bulk fill front half that seals the tube - hipac requires the front half of a co2 valve to seal against the face of the hipac. Odd -

Stevev,
No offense intended. I was just trying to expand on both of our responses to help him out. Sorry if I offended you.

Everyone interested in what really happened needs to watch this all the way through.
The hipac was modified - the section that mates with the co2 valve face was removed, as in cut off, and a COMPLETE Discovery valve was used.
So instead of just the tiny face of the c02 valve seeing the pressure, the larger surface area of the Discovery valve face was seeing the pressure -
and that valve was only pinned with ONE valve retention screw. That would be asking for trouble with an unmodified Disco, so no different with the modified/altered hipac.
ALSO - he used two barrel bands, one right over the edge of the 22XX tube/hipac junction - don't know how tight he had those grub screws - could have been a contributing factor.
Just a thought...
