Need a Good Quality Scope For a Marlin 45

[345 DeSoto]

This might seem foolish to some, but the old eyes not being what they once were, I need a good scope for a Marlin M45 Camp Carbine. It needs to gather light really well, HOLD ZERO, and most likely be a 4X. Could also use some recommendations on mounts...

Have settled on a Redfield Widefield 2X7...
