Pellet Gun V2

Heres my second version of the pellet gun I posted earlier. The main improvements are a stock made from thin walled PVC, a larger hole for the valve and the hole closer to the o-ring. This version is slightly more powerful and much easier to aim. So far Ive been able to hit a coke can from 20 feet with ease and have not tested any further. I have a video and will post it as soon as it finishes uploading.
Heres V1.

Looks better now. Paint would make it look even better. Good job.

Yep. I think I might make something similar. It seems easy.

It is except drilling a hole through the barrel, its a pain, the larger you make it, the harder the barrel is to push back, I made a model with a 1/2 inch barrel and I could not fire it at anything above 20 psi

Yeah it is only good on small caliber, it sould be easy to make a bb gun with two chambers for multiple shots. I think it would be cool.

Yeah it would, this is a lot easier to make than a piston valve this size

That's cool... I think you should make a real trigger...

I was thinking about adding a spring and then bending a small piece of metal as the trigger, it will work like the trigger mechinism on a airsoft springer but for now it work ok to just slide the barrel back
