I thought I had a blueprint with the upper rail sizes but it looks like I was wrong...  Does anybody have a source for a print or drawing that shows the dimensions for these...

I realize that when building it is best to undersize a little and fit the receiver to your parts but many of these dimensions are pretty much standard and it would be nice to have a digram that shows these instead of tons of trimmin, fitting, timming, fitting. etc to even get close...

Anybody have one?  I might be able to draw one at some point if it doesn't exist...

rail prints

sorry this is the lower, mis read your post...

Head over to Pookie's site, I am sure you will find a diagram there.  Or at least a SWAG..

I don't have a direct link, just go to Gunco and search.
