My Shiloh '74 'Business Rifle' wears a C.Sharps vernier tang. I have on hand an MVA mid-range tang I bought for my 50-70 carbine, but it shoots so well with the barrel sights, it has never been mounted.
I just bought a Ped '74 'Silhouette' model during MarStar's 'Black Friday' sale and it's going on that rifle. I may need to order a Ped sight base from MVA if the hole spacing differs from the 2.260" Sharps base. In that event, the logical thing is to order a globe from MVA at the same time.
Edit: After reading reviews of the Ped front sights, I'm going to bite the bullet and order the MVA sight with internal level. It even has internal x-hatching to kill glare. They come .003" over size and require fitting. The Ped is said to be "an easy fit" which means it can just as easily "unfit". What can happen will happen .....
If the Ped barrels are as good as reputed, good sights will maximize that potential.
