This is my mini pneumatic i made today from spare parts laying around. The barrel is a bic-pen tube inside 3/8" air hose with a 1/2" sleave for aim. The chamber is all brass and steel with a schrader and a female QC. The valve is a 1/4" ball valve.

Edit: Just shot it at 250 PSI with a 6mm steel BB. It went through 2 layers of double wall cardboard!

For a spare part gun, it 's nice. But awfull performance man. 250 psi, 6 mm steel ammo, and only two pieces of carboard ? At that pressure it should at least go through 1" plywood, dont you think ? But of course, it is made with a ball valve.

Anyway, nice afternoon project.

WHAT! 1" ply? A real pelllet gun at 1200 FPS can't even do that. The 2 layers of cardboard is quite a but for this gin with a 5.5" barrel.

hmm, I shoot a 25 mm and a 16 mm marble trough such a board at 100 psi. You use 250 ...

That marble has much more mass and there for much more inertia. That is why it penitrated.

So, why the qc at the end? I'm guessing for a stock???

So i can connect it to my compressor for rapid fire!

I like it. It would be fun just to play with but a pain to pump up. Your guns perfomance seams fine to me because you using a fitting for the chamber.
