I like it as it is as well, it has a post cold war soviet style to it, looks rundown, but still deadly, just to clarify, from the T towards the stock what in order are the components, an secondly how do you get the second section of the sniper barrel to seal.

I just screw the section onto the coupler on the end of the barrel by hand. It shoots just fine, but I like the shorter barrel better.

I agree with you guys on the looks, but a coat of paint would look good too, but eventually it would look like this again.


name the fittings from the tee /w/ the piston in it?
ok, here it goes....

3/4 to 1/4 inch reducer, short 1/4 inch pipe nipple (not sure what size), 1/4 inch tee, short 1/4 inch pipe nipple, 45 degree elbow, short 1/4 inch nipple, blowgun.
off the side of the tee, I have a short nipple (1/4 inch), an elbow, a ballvalve with a 1/4 inch opening on this side, and a 3/8 inch opening on the other. after the ballvalve comes a 3/8 to 1/4 inch reducer, then the air comressor connection/connector.

UPDATES:

(sorry for the double post)

I spent a couple hours in the barn over yesterday and today, and added a drilled barrel shroud, extended the stock, sleeved the pipe nipple behind the valve /w/ copper I polished with my buffer, and extended the stock. now you hold it like a real gun

this target was shot at @ 60-90 psi, tonight, from 50 feet away. I was making different types of ammo, and testing their accuracy.

That's not bad accuracy at all, especially since you haven't got sights!
So what did you figure the best ammo to be?

steel bb's.

they fly straight, penetrate, and it is very easy to build a clip for them.

/w/ a couple modifications, nails work very good too. but My dad doesnt want me shooting nails for many reasons. (which is understandable)

I want to get some blowgun darts and a cheap blowgun to turn into a barrel

If I paint it, all the copper will stay shiny, and the rest will go flat black.

that stock will look good flat black.



jrrdw, I dont want to kill anyone! lol....... :lol:

If that gun didn't have a barn to be stored in, you would have to build it one!!
With holes in the roof!!
Love the accuracy, love the stock!!

Muhaha.
Seriously,
that thing has got Mad Max written all over it.

It would be a shame to paint it.I like it this way.

it's......raw
