The FXII 2.5X doesn't come in silver I think, if that is an issue. The 5" of eye relief suited my 444 well. I sure like the 1-4X versions I test at stores. I had a Redfield mounted on a 243 BLR years ago. Worked like a charm for deer in southern Sask.. I'm considering a 2-7X for my first bolt in many years, 223. I find the 4X about my limit of sight picture shake off hand. A 4X fixed would also grace that Marlin real nice.
I would still pick a BLR over a pump, based on pure lever prejudice only, if higher performance spitzers and pressures were wanted. Pumps are fine actions and fast repeaters that don't disturb the trigger hand like most other actions.
