victory cp2

[stubbs4612]

Hi all,I have victory cp2 co2 .22 but i want to make this a pcp instead of co2 capsuls but i dont want to go the dropblox way ,i was thinking a screw in tube with a pressure guage has anyone done this ifso where do you get the parts from.rgds stubbs4612

The conversion isn`t really doable I think as the valve unit of the CP-2 is not sealed in the cylinder so would need hefty modification. Also , the valve itself is designed for the low pressure of co2 and I doubt it would hold against typical pcp pressures ( 200 bar `ish ). Then the hammer spring would need to be stronger to open the valve against the increase in pressure.
Just buy a pcp .... it willl be cheaper ( and safer ).

just buy a pp750 sa or similar. or even just a cheap chinese PCP. £200 and a much better outcome, offset by selling the cp2, job done.

[--ped--]

pp800 is the pcp version of a cp1 and i think that you can get the tube valve and cylinder from bagnalls at a price but easier to buy a s/h 800 and swap parts till your happy

Hi it just so happens that I’m doing a conversion on another of my victory Cp2,s. This time a full HPA conversion and not just to use an 88g co2 cartridge. The parts need are quite readily available here and in the USA. I managed to get hold of a good used Cp2 for not a lot of money, so this conversion will probably cost me about £170 in total. I’m away from home at the moment but as soon as I get back I will be making a start on this very popular conversion.

For anyone still interested in converting a Cp2 to HPA, this is what I’ve ordered so far, and at a total cost of just under £180 including downer Cp2 and postage. Number, 1, and most important the drop block which enables you to use regulated HPA, Number, 2, the regulator which can come in fixed or adjustable outputs,3, the air cylinder, the most common one is the 13Ci, 220cc Bottle, agin these can come in different pressure ratings I’ve gone for the 4500psi inlet pressure ones.

and this kinda makes my point.. you are in for say £180.

You could just buy a dedicated cheap PCP for the same money. I mean, if you are just doing it for the fun challenge, which I get, cool.

But practically, there are much better routes to cheap PCP ownership. I've bought Kral PCPs in need of nothing more than a couple of hours servicing and tuneup for less than that £180, and I'd venture that they are much better options for most people. Better triggers, barrels, support for parts, and just more solidly made.

but for a shed-tuneup project, hey, why not

Those routes are only available to people who have the skills needed to do the repairs lol.
The Figures I quoted do actually include the price of the doner gun, so the actual cost of the conversion wasn’t too bad.

I get you, and I'm not trying to put a downer on folks who want to do these kinda conversations... there's room in this hobby for all of our approaches to gaining enjoyment. It's just that if you want a PCP it's easier to start with, well, a PCP

I think there a similar saying in the car building / modifying circles... "if you want to make a fast car..."

[pss1556]

It’s just that a lot of the pcp rifles for sale these days are quite expensive to buy new, the cheapest one and probably the most popular is the Victory PR900 gen 2 regulated multi shot pcp, at about £190/210 new.
What I was trying to do was answer the guys original questions regarding converting a Cp2 to use HPA, and I think that I have just done that.

The conversion isn`t really doable I think as the valve unit of the CP-2 is not sealed in the cylinder so would need hefty modification. Also , the valve itself is designed for the low pressure of co2 and I doubt it would hold against typical pcp pressures ( 200 bar `ish ).

good advice there.

that's what I'd do.

This is probably the most easiest conversion to HPA available, and I really can’t see what the problem is.
1, you no longer use the original tube, 2, the valve is more than capable of handling the slight increase in pressure ( 850/900 psi co2, to regulated 1200 psi HPA), 3 the same action, hammer, barrel used on the pcp pr900 model ) 4, very easy to tune, 5 very little work needed on hammer spring to obtain best results. I would also think that most most people would be able to do this conversion at home.

[Antoni]

What if the regulator fails/leaks? Not 1200psi, possibly 4000psi.

[pss1556]

That’s a good point, but the supplied cylinder is rated to 300 bar. I think that the weakest link is the exhaust valve in that case. I’ve never heard of any problems with this type of conversion!!!!! Also the inlet and outlet side of the regulator is fitted with burst disks.
