Copper shot gun

Unread postAuthor: BlackH » Wed Oct 08, 2008 2:35 am

This is a "Shotgun" i made Works at 200 psi and the copper pipe under the barrel has 2 connections to the chamber to increase the volume of the chamber and the rear sights can be set left and tight and the front sight for up and down.

Another fine specimen from you Black!! Great design and workmanship as always.

How are you connecting the bottom copper pipe to air reservoir? I can't see how you are doing that.

Nice!
It looks like a simple BV gun at the first sight due to the very compact build.
I like your way of connecting the two chamber parts. How were you so sure that that worked?

OOOOOO believe me that was 1 hell of a job (i like stuff to be straight) my main prod was to make sure the 2 small pipes going into the main chamber does not press against the barrel inside the main chamber

And its not quiet at all!!! bothers me a bit but o well if you need a nice gun sometimes its load
