AO: I'm working on a project that needs some "old school" flair. I was looking into the old sidecars that Planet Eclipse sold and really wanted to track one down. I haven't seen many aluminum PE sidecars for sale so I decided to try the DIY way...

While looking at the side car I felt like I could buy some mount rings and an aluminum cigar tube.



The only problem is that I want to mount it to a stock and not an automag sight rail.





Are there any cigar or firearm experts out there that could identify what i'm looking for?
