It's not quite finished yet I still have to scope it. I did the valve mods, put on the 1760 barrel and put in a 2200 piston. Not much else I can do. You guys have any suggestions? From 20 feet at full power which is 30 pumps or so it goes a little more than half way through a 2x4.

How long is the barrel on your gun and what difference is there between the 2200 piston and the original piston that was in the gun?

My barrel is 24". And the difference between the 2 pistons is the original piston is plastic and the 2200 piston is metal. and metal builds a much better compression.

yes it can compress more... but what seals the air? is it the same cup as is in the 1377? if so you wont get any difference from it. shouldnt anyhow.

Yes the pump cups are the same. But on the 13xx mods page it says metal gives better compression. And I can really feel it to. It gets really hard to pump.

Yes it works really well indeed. You should try it. But you said you already made a brass piston for it. It should work just as well. Good Luck!!!

Did you paint the forarm?

Hey, don't hate. It releases negative energy, which is bad for everyone.

Yes I wanted it to match the rest of the gun.

Looks like it could do a pretty good job at hunting.
