Thanks for the great input.

Knowing nothing I have a few questions:
1) What do the numbers mean? How do you settle on a specification?
2) Some shown sit back on the receiver, some forward. What does that mean?
3) Seems I'd need to develop a list of items, scope, covers, mounts and rail? (All matched for the 1894SS)
The Leupold factory is not too far, maybe I should go there for help??
Seems you can spend whatever, thoughts? Some I found on Midway:
