My neighbor has a Marlin Guide gun he's lending me. It's got a peep sight (looks like a Williams) that sits really high. I asked about it and he said he'd changed the front sight to one with fiber optics. The fiber broke off and I can't get it out, which makes the front sight almost useless. I've soldered a ball of solder on it to get it a bead that is visible. I had to use my kitchen gas range to do the solder, not pretty but it did improve it a lot.

My long term fix is to replace the front sight with something from Marbles with a gold bead, and ideally lower the peep sight in the rear down so that it's closer to the receiver. I think to do that I have to get a front sight that is shorter (the current one is pretty tall) - because if I lower the rear sight (which moves bullet impact lower) I'd need to lower the front (which moves bullet impact up) to keep things copasetic. Is this correct?

Lastly - does anyone know the base dimensions on a guide gun front sight?

thanks...

The fiber broke off and I can't get it out, which makes the front sight almost useless.

Fiber can be melted out with a Bic lighter. Heat it and remove. Give a call to TruGlo or Williams. They can sen more fiber in your choice of color and its simple to replace.
I had to replace the front fiber on my TruGlo shotgun sight and its too easy. Insert, cut slightly longer then use a lighter to put a bead at each end.

First of all, is the rear sight adjustable? If so, I'd look at the "fudge factor" to allow yourself to bring it back down. Ideally if you keep the same pitch of your sights relative to bore axis you should be fine. Meaning, if you lower the front and the rear the same amount, things should work out fine.
