First Poly Piston Gun - Black Gold.

[Mitchza89]

This is my latest creation. I decided to make a piston valve using entirely out of poly pipe fittings. I think the gun itself turned out quite well. I wanted to make something that could be pulled apart and stuck into a bag, but I also wanted to be able to change the barrel/chamber of the gun. It's just about finished. I had a blowgun actuating it and it worked quite well, but I want to add a modded sprinker valve and add a small stock.

Anyway, enjoy .

(It still needs a bit of a clean up...)

Looks really good mitchza. The new barrel(hopefully longer) will improve performance a lot. What pressures do you run it at?

[battlemonkey]

Good looking, nice simple gun. What are you using for ammo

[Carlman]

nice one mate!!

gotta love bunnings

[Mitchza89]

Cheers alot guys. I plan to run it at 200+ psi so it should have a fair bit of kick. I've got a 1m barrel that I'll use marbles for. I'm happy with it .

good work!

looks good

[Mitchza89]

Thanks mate.

paintball barrel + 50psi should be safe

[Mitchza89]

50psi in a gun like that? That's child's play But as far as actual paintball goes, 50psi should get me velocities close to a paintball gun.

[SpudFarm]

that was what i meant.. you can have a nice war

this stuff is poly pipe mate, its good to 500

Very nice, and at elevated pressures the performance should really be something, los damage pics por favor!

[SpudFarm]

ohh you don't ynderstand

if you use just 50psi you can use it just like a normal paintball gun

[Carlman]

ohh you don't ynderstand

lol ah k getcha now

but if you want to obliterate something you go high

[Mitchza89]

500psi?! Damn... I didn't know this stuff was rated that high. I saw a sticker on a piece of poly (not the one I got) but it said only 1750kpa I mean that's bloody terrible...

I've got a coax bb gun that uses a 600mm piece of 1/2'' poly, and it's holding perfectly at 300psi so I'm not sure

Cheers for all the comment's lad's
