WILLIAMS FP-H&R Receiver Peep Sight and Lyman 17A Globe Front Sight

[Retreever]

I have a H&R 1871 Buffalo Classic 45-70 Rifle (32" barrel) with this sight combination. I have the Williams peep sight at it's maximum height and it is still shooting 6" low at 100 yards. I took some measurements today and it looks like I have the AUG version of the Lyman Globe sight which is the tallest of that series at 0.584" from bottom of dovetail to center of the aperture insert.

If I understand this correctly to improve the situation my options are to raise the Williams rear sight ( not possible) or lower the Lyman Globe front sight.

There are (2) others in this Lyman 17A series. The AMI model which is 0.494" high or AHB which is 0.404" high.

Would either of these help raise my point of impact to equal point of aim (hope I have these terms right). More directly I want the bullets to hit where I am aiming at 100 yards. Just for general info with same combo ( different height on the peep sight) I am shooting 8 round - 2" groups at 50 yards.

Any help or feedback would be appreciated.

Thanks

I'd go with the .404 height front sight, that way you will still have some height adjustment with the rear peep sight.

get your hands on what is referred to a buffington rear sight. came with some of the krags and trap doors. slot one of the holes and stick it on there.

Yes, a lower front sight will solve the problem.

Thanks everyone who posted here - I actually found a discontinued Lyman 17A Globe Sight - model is AHT and height is ~0.378 and hope to have it early next week. I posted my question on a couple of other forums and based on feedback there and here this front sight height should give me range out to 300-400 yards possibly as much as 500 yards. Once I've swapped in the new sight and had some range time I'll let everyone know the result.

Checked out the Buffington Rear Sight, very kewl, wish I had known about it before. I have a Smith Enterprises M95 Ladder Sight (used) , trying to find or make a base with a dovetail that I can screw to the barrel and mount the ladder sight so I don't have to cut my barrel. Still looking for the base.
