Well All I have really for you to see is the video because I don't reall have any pics of it yet. It is regulated co2 and without a barrel already packs a punch! All input needed! I ant this thing to run top of the line, you can tell from the gauge in the beginning that I am regulating it at about 300 psi. I'm nervous lol.... :?: I am not sure of the pressure that the tank will run out at but I would love for this gun to run at 600 psi, so we will just have to see... I'm waiting on the youtube to upload then ill post the link.


Ideally i would love to make a wooden stock and have this all put together in one stable machine... but I need your guys' help to get there! :idea:






***EDIT- Would a pop-off valve make this semi auto for sure if I could find a way to properly feed the ammo?

This is the regulated co2 setup i have... the hose is from a filling station and it works really well in the video.

This is the basic layout with before the co2 with the shock pump.

it can handle high pressure, only problem might be that the blowgun starts to leak,

also how do you plan on going semi with this?

so it does work properly... what was the problem with it ?

I find it hard to restrain from suggesting switching to a DCV :D
it might seem as a more complicated route as you can't get these things in a hardware shop but at least you could get something that is much stronger than a blowgun

so the two things that you can improve here is to reduce pilot volume and get a valve that can handle 600 psi... which is why I suggested getting a DCV

I guess you knew I was going to say it

I have access to a lot f tools in my garage so I will be putting a nice wooden stock on here. I am just trying to figure out how to make it semi auto. Just got done pressure testing it at 500 psi with 0 leaks so I think once I get the barrel It will be ready to go. I might have to reconfigure the pilot setup so that the stock works well. I ill eventually add a bolt action breech as well but I need to configure the trigger/mount setup. If anyone has schematics for stocks or drawings or ideas it would be greatly appreciated.Thanks !

Spring loading the QEV piston should give you semi-auto easily, after that it should not be too difficult to add a barrel and magazine. What calibre did you have in mind?

As to stocks, you might want to consider buying a cheap airsoft gun and using the shell :)

Come to think of it, you'd also get a 6mm barrel and magazine, and for damage you could substitute airsoft BBs with these ;)
