I got a 410 bore single shot for $20 a while ago with no wood and no fore arm Iron. It was such a compact unit I thought I could make something out of it that would shoot up all the 410 bore shells that I have accumulated over the years. Today I had it together enough to see if it would shoot and it does. So now I have to get some more shells for it. The butt is kind of a prototype made from a chunk of 2x6 that has almost no visible grain and is very soft lumber..... easy to shape and sand down therefore. I say prototype because although the slot where the action slides in was tight when I started out it got loose and mis-shapen before I got the action all the way seated. I bored the hole through the butt for the stock bolt free hand and almost hit the X on the butt. It was okay to shoot for now though. It does tend to shoot high though set up as it is. The barrel and action are Japanese manufacture with the name Falcon stamped on it and also it is marked 2 3/4" chamber length, and full choke, 3" shells did fire alright through it however. I made the fore end iron by laminating three strips of 1/8" x 3/4" steel stock together by riviting them together and fitting it to the pivot axel and the lug that locked the original iron. It is secured by a cross pin through the lug made from a piece of a 16 common nail. it is secure but can be taken apart easily if needed. I have not yet finalized the wood for the for end but it will be small and as simple as I can make it. So it fires , it snaps open when you want it to, it ejects the fired hull right over your shoulder. And it was cheap! I think I have a good rabbit gun here.
