Ok so Im starting a build on this .458 Win Mag carbine. Keeping with the classic African style rifle I wanted to go with the banded front sight and a express rear sight mounted on a quarter rib. After laying out my quarter rib blank on this barrel its no problem contouring it to fit over the smooth barrel nut and mating up with the front of the reciever but with the height of the express sight on top of the rib my front sight would have to be a half inch tall and thats on top of a banded front sight base, this sight would look like a sail boat on the end of the barrel! I know the Lyman 57 and I think the Williams FP 10 reciever sights are listed for the Savage 110 but the action Im useing is an older 110 with the flat top rear ring, nothing on either sight states if its for round or flat reciever.

So to my question. Does anybody know if the Lyman 57 or the Williams FP 10 will mount to the flat top reciever? I dont want to spend dam near $100 on a sight if it wont work.
