Newbie question I assume getting a Cothran tube I would pin the valve on my 2240 for running HPA and what all do I need to do to a bone stock 2240 to run HPA? Thanks
2240 HPA
- Thread starter desertplinkr
- Start date
Run a dummy co2 and modified end cap and of course pin the valve and Run a good hpa tether line to a paintball bottle with regulator set no higher than 1200psi if you want to go cheap. 1500psi burst disc for added safety.

Or you can just run a Baker bulk set up and secure the valve with three 8x32 grade#8 screws. You may need a stronger hammer spring like from a Discovery or similar as well. Good to 2000psi with this set up. Although I would highly suggest a 2250 tube for a better shot count and a steel breech to help keep the extra pressure in the gun.

But there are lots of ways of doing things.
With the mods mentioned the gun could look similar to the bottom in the pic.

Thanks BioHazard
I should have explained further, I don't even have the 2240 yet But I ordered the XL so already has the steel breach. I replaced a plastic breach with a steel one on my 1322. I don't want more power I am just looking at options to get away from CO2 and move to HPA without too much expense. Are the 2250 tubes a direct match to the 2240 except for longer? Meaning all the slots and holes line up? The main thing I am worried about on pinning the valve is I have never done anything like that before? Don't really have the tools, no tap and die set.

Careful! Just May be more cost efficient to buy a P-Rod or 1701P or 1720T with the 25% AGN discount direct from Crosman when ordered on Friday for free shipping and have very good warranty and no tinkering required.

Yes the tubes on the 2240 and 2250 have the same holes 2260 is the same also. Well I guess you found another way to do it. There was no such thing as a 1701 when I went about my mods back in the day. Looks like a nice gun. enjoy.

I debated about building an HPA 2240 also but decided to stick to the purpose built PCPs with the purpose built valves and tubes in part do to lack of tools and skills needed to pin valves and so on. Adding up the cost to convert a 2240 put you right in the neighborhood of the 1701P, Prod and 1720T anyhow. At least for me because I can’t machine and make my own parts.
I just got a 1720T and now I have a complete set of all three. The 1701P is a great little pistol. Wished Crosman would have designed it to be able to use a magazine like the Prod. The magazine is a challenge for open sights though so I understand why they didn’t. The Prod and 1720T are a little too long to be pistols for me so I shoot them as carbines. I really wanted a .22 cal magazine capable pistol the size of the 1701P but since Crosman doesn’t make such a thing I built my own.
if you ever want better grips for your 1701P contact Vernon Austin. He makes nice laminate grips for the Crosman’s.

Really neat how those Crosman PCP pistols can easily just swap them parts over. I think the 1701P is the perfect pistol, size-wise. Add a TKO with shotgun sight up front and a Williams in back and there you go! Vernon makes very nice grips too. Personally, I prefer Steve Corcorans' though.

I consider the 1701P a true handgun; actually holsterable, and shootable from a traditional offhand position. The Prod and 1720T are much more along the lines of "Hawg-Leg"; better results from rested positions but more than a little cumbersome... especially offhand.
Agreed that Corcoran produces the coolest grips, but Vernon Austin's are much less expensive. I believe both guys offer laminated and real wood (walnut).

as a follow up I shot my bone stock 2240 over the Chronograph today and it was hot in the garage 90 plus degrees, string started out 470 with 14g pellets. Only got maybe 25 usable shots then the fps dropped off a cliff. Ordered a light hammer spring to see if I can get more shots. with the heat I hope I don't get valve lock with the light hammer spring, if I do I will just be happy with 25 shots per cart. Lighter trigger spring it's a nice shooter will do accuracy once the 2240 gets broke in. Waiting for delivery of the 1701P.
