this is my finished marble piston rifle with test camo paint job 8)
it is made completely out of 20mm pressure rated pipe and the valve is piloted by a 1/4 ball valve. this is currently my favorite gun at the moment
1) because it is so much lighter and nice to hold then my other guns
2)its quick to pump up :D

Very nicely made cannon, really.
The only minor things I could possibly critisize is the pilot volume, which is quite big due to your pipe; and the kinks in the chamber restricting flow. But they not major issues, so very well done. The decent sprayjob is very nice, and gives the gun a beautiful finish.

Wow, very nice. It looks like your barrel port is a little too big for you piston. How did you get it to work?

Oh, a question ( 8) ): What pressure do you like running it at?

Very beautiful stock configuration. Looks like one of those proffessional bb guns that are used for competition. The striped paintjob is pretty cool too.

All heil the spud-reich!


But the paint job reminds me of a paintjob Jack showed me once, I can't find the link back to it. The camo-tigerstriped pistol.
