That is a very nice looking action. Congratulations.
I want production Raptors to have rails that extend clear to the end of the receiver just behind the recoil lug. This is so that we have more visitility in scope mounting location as well as offering more rail space for rail accessaries if wanted.
Just a thought and a comment on a problem I have encountered before particularly with Ruger #1s. The location of the rail and slots is determined by the stock and the shooters eye. Eye relief is fairly constant from scope to scope. Your customers who can actually afford these things are getting older and need 50 to 56 mm scopes. This can cause a problem of contact of the objective bell with the rail if it extends too far forward. This then causes the need for higher rings which dominos into needing an adjustable cheek peice.
I certainly agree that as far as looks go, that the rail should go to the front of the action, but right now I am having the reverse done to a gun. I am having a rail custom made from bar steel and cantilevered back toward my eye so I do not have to crawl up the stock to get the right eye relief, and with a short front section I will not have to worry about the objective bell clearance of the rail.
All of that said, if I was the expert I would not have you and others build my guns for me. But it is something to check. Maybe have a short rail and a long rail option. Or, I am sure you have a hacksaw to cut one off shorter.
Finally, you should remember some of us are not really sane but are on work release programs from the asylum and we will be needing a gas relief hole in the receiver when we put too much powder in the case.
