Damn, nice job on the cannon and the pump. Super clean construction, great work. You seem to put a lot of time and effort into your builds.

I like the gun and the pump a lot also. Very clean construction. Oh, and don't worry about your English too much. As long as we get the idea, we don't really care. Did you use a popoff valve for the pump?

Nicely done, if you had a proper sight on it and were shooting from rest I'm confident your groups would have been much tighter ;)

A specific parts list for the valve, that someone could translate would be great. A bunch of people have already said this, but that is a VERY nice gun, and a pump to go with it. I'm also wondering what those slugs (pellets) are made out of, they seam very good for homeade.

the gun run at 130 psi ( 9 bars ) and the air chamber it's an aluminum bicycle bottle , and i can put a maximum of 200 psi

the barrel is a high polished cooper tube :wink:

i love it because he have a exellent accuracy , next week i'm going to put a red-dot BSA 2x42 tactic :

also with the scope you should make a stock for it and then youd be takin out tanks :D but other than that you could get a bolt system for it like on your m25 sniper. btw awesome job and welcome to spudfiles :D

My money's on cast lead since there's a mould there and precious few other metals are worth melting and casting at home.

The copper pipe looks a fair bit thicker than the stuff we get in the UK unless it's the camera, also looks like a very nice pilot, is it an actual air blowgun or a water spray gun?

Your soldering (sweating, whatever you want to call it) is amazing, incredibly clean. I recently soldered for the first time and....yikes. How did you get it so clean (or did you never get it dirty in the first place). Great gun.

I have been wondering, how do you fill her up, I see no shraeder, presta, quick connect, ball valve or anything. Do you just fill it through the bottom of the blowgun?
