Automatic Piston Gun

[Kobl]

I have recently been looking at Marks full auto marble gun here. I recently began construction on my steel (black and gavy) bb gun and was wondering if his full auto system could be adapted for use on a homemade piston valve. The chamber is 1/2x12" with a barrel sealing tee valve with both copper and airsoft bb barrels.

Thoughts and help would be appreciated,

Why not, after all the QEV is a piston valve anyway operating on exactly the same principles.

Not to be a nitpick, but QEVs like the one on mark's gun is a diaphragm valve.

Doesn't change the overall answer to your question though... you sure can use it

im pretty sure QEV's are super light-weight piston valves.

I'm pretty sure that I've taken enough of them apart to know that the vast majority of them use a diaphragm.

doesn't matter which it uses, both do the same thing. as long as you are dumping pressure into the barrel it doesn't matter how. you could use a sprinkler valve or ball valve or whatever, and it would work, it would just be less powerful depending on the type of valve. but yes, a piston will definitely work.

Not to be a nitpick, but QEVs like the one on mark's gun is a diaphragm valve.

Since some QEVs *are* co-axial piston valves and the piston/diaphragm valves operate on the same principle, I think all the evidence points to you in fact being a nitpick

[NeoSpud]

Alright, I admit it, you've "outed" me! I am indeed a blasphemous nitpick!


I blame my perfectionist parents; it isn't my fault!

[jackssmirkingrevenge]

yes yes, blame the parents... honestly, is there anyone left in the litigation loving US willing to take responsibility for their own actions?!

[NeoSpud]

Well it's all those pompous Europeans' fault, with their philosophy and solipsim and gibberish nonsense!

Plus, passing the buck is a lot more fun.

I'll drink to that cheers!
