This is my latest gun, it's a 1/4" QEV airsoft gun. The air chamber is made out of 3/4" black iron pipe, and the barrels are 5/16, and 1/4 brakeline. I made the gun so I would have something to shoot in the winter when it's too cold for pvc. Enough said, here are some pics.
Here's a video:
Edit: I put up some damage pics, but I've really only taken pictures of tomatoes that I shot, so those are the only damage pics I have.
Edit: I just put up a new video:

holy wow. i love the look of this gun. My only complaint is that your chamber is massive overkill. shorten the chamber or make the barrel a hell of a lot longer.

Well, I wanted the chamber long enough to make it feel like a real rifle, but I guess I could make the barrel a bit longer (or block off the stock of the gun).
Edit: The gun shoots around 500 fps (just a guess, haven't ggdt'd that just yet)

what pressure are you using?

Usually 100 psi, because that's as high as my compressor can go, but I'm planning on putting a schrader valve on the gun soon so I can pump it up to 150 manually.

It's very accurate, and I'll upload some damage pics right now.

That would be sweet if you could use more pressure. If you used a smaller chamber, a shock pump would be a viable option.

Well, I don't want to take it any higher than 150 psi, since that's what the QEV is rated at.

But still, that would be a reasonable increase.
I'm a little lax about some ratings (but I usually stay within or close to most)- I use a 145 psi QEV at 320, and it holds fine. Quite a poor example to set, but those pressures are great fun.

Well, there are some ratings that should be followed closely (pvc) and some that can be stretched a little (compressor blowguns).

Looks like a realy nice BB gun you have there.
Just a quick question... Did you epoxy the breakeline into the threaded ftting for your barrel? Because I have my barrel attatched realy ghetto-y on my BB gun.

The brakeline has a flared end, and it came with the fitting already on it, so I just attached the threaded fitting to the QEV.
