Looking for tang sight suggestions for an H&R Buffalo Classic

[QuarterBoreGunner]

Hey there CGN, so I pick up a Harrington & Richards Buffalo Classic 45-70; one of these critters here:



And to wring the most long range accuracy out of it I plan on mounting a tang sight like so:



And I'm just looking for suggestions; realistically I don't anticipate shooting past oh say 500 yards, but who know?

I know Marbles makes a few and I've found others, but I need a little direction I guess.

I have Pedersoli tangs sights on both my Springfield Trapdoor and Sharps both are 45-70 they work great but are bulky.
Lyman & Marbles come to mind. I upgraded the Williams peep on my Buffalo Classic to a FP with target knobs.

Does the William use the same screw holes the stock sight does?

EDIT: found them

70260 FP-H&R-TK For Buffalo Classic and Handi rifles. (With Target Knobs.)

Nice.

That looks pretty nice, and it's a drop in so no messing around with drilling the stock...mmmmmh. Interesting.

And I already have a spare Merit target disc.

I also put them on my Marlin 1894 44 mag and my Marlin 1895 45-70. I'd think it will do everything and more in your rifle.
