Easter Egg.


Poor wall


Rifle Specification

-1/2" 50cm long barrel
-1/2" qev

English isn't my mother language so,sorry for any mistakes

haha buon lavoro! simple standard parts and well put together

With the all-metal construction, I hope you're taking it to high pressures.

Of course it wouldn't be an Italian project without a shot at a Kinder Sorpresa type target

For a bolt and magazine, check out this recent tutorial: http://www.spudfiles.com/forums/how-to- ... 24038.html

Thank you!Damages shot are done at 10bar, that is the maximum pressure for qev,slide valve is rated for 16bar.

Just because it's *rated* for 10 bar, doesn't mean you can't take it to 30 bar
We routinely use small QEVs at much higher than their intended pressure with no failures. They're built for industrial use, so they usually have high safety factors.

Add a gun handle and clamp your trigger on to that slide valve, and it'll be a very comfortable gun to shoot.

Ouch, that barrel is a killer. There is often a seam down those iron pipe nipples. A nice 1/2" copper barrel (longer too) will be much better nice gun!

Thanks all for the advice!

Nice! But I believ you could get away with a 1/8" paintball slide valve for your pilot. It would make a more comfortable trigger + you could then take the setup up to 500 psi with a nice safety margin.
