45-70 BFR sight/spring questions

[spaniel]

Does anyone know what the factory sight height is on the 45-70 BFR? I'm looking at the fiber optic replacement front sights, they don't say on the website what height is factory.

Also, anyone know if the Super Blackhawk hammer spring fits? I've already gotten a couple FTF from the factory spring being marginal.

I take it you are going to change the front sight . Call MR they will know free ?

As for the spring buy one when you call them ?

Yes, I can call them.

I can also ask questions to inform myself before I do so, as many company reps are not perfect or experienced and dispense inaccurate information....
