Does anybody know a good website for pellet/bb gun diagrams? I need to see the internals of a crosman 760 pumpmaster.

it is about the crossman 2200 but i am pretty sure the valve will be similar or the same.

Thanks guys, I was wondering if it would be possible for me to mod a cheap 760 for higher volocity 700+FPS.

I suggest building your own hammer valve, it is alot cheeper and can be made to any dieired size also you can understand how it works and so improve apon it and be sure it holds the pressure needed.

Several mods you can do:

-longer barrel

-stronger hammer spring

-heavier hammer

-bored out valve and transfer ports

-weaker valve spring

Sticky, the Canadian version has a pressure relief valve threaded into the valve chamber.

Those that I've "worked on" had a hex head screw accessible through a hole in the plastic. It's just a bit in front of the trigger guard, on the bottom.

Turn the screw in snug and see the difference. :)

And yes, you can get 700+ fps out of it, but you'll need to "open 'er up".

Alot of animated diagrams.
Though these diagrams are more general. I am not sure if you will find the right one for your specific marker.
