Hi all.
This is a project that i finished some time ago.
Its a springloaded ballvalve pneumatic airgun, wich fires by a push of the trigger.
I load it with about 8Bar, that equals 116PSI.
It's quit powerful, and distinct.
the pipe is shiny-chrome copper-pipe and the rest is some scrap metal i found at home.
well, hit me with your thoughts, but please spare me the "give it a paintjob" comments, I do can count that out myself.

Very nice. It would probably look even better with a stock on it.
If possible, you should take the pressure higher. Also, some damage pics would be nice.

Cool, is that just regular copper pipe? Nice scope, what is the accuracy like

That's one heck of a screen door spring you have there...it is a unique feature however...maybe a little out-of-place looking....maybe you could hide it inside another pipe there.
Otherwise, looks like clean and solid construction.

Amazingly nice construction!. I started work on a springoaded ball valve gun. Better stock, everything else is crudier:( I've had a lot of trouble getting the springloaded set up right.

hey that really good looking gun - it seems that it can take 300 psi easily
in case you want to improve performance consider buying a QEV valve

With that spring I bet the valve is opened to full barrel diameter in less than 10 milliseconds.

That is a very similar spring loaded setup to the one i used on a cannon I posted a while ago, it does improve the power over just a ball valve incredibly, the only difference to mine is the trigger setup and the type of spring.

-Yes, it´s a quick and distinct opening of the valve.
POLAND_SPUD; Yes i know. I just haven't made my self a proper shockpump yet
.
starman: i like the exposed spring, i mean, in this case it does a lot to the appearance in a good manner i think.
hubb017: yes, perhapse.

Nice gun, but I do agree, make a stock, and how is the accuracy.

the accuracy is pretty good. But a huge setback is that i don´t have any good type of ammo. I have though of crafting some slugs but i haven't tried it yet.
