Gotta ask, 'cause I don't know ... Shooting Masters, Officer's Model Targets, and others' front sights - the early ones, before the ramps and one pieces and pinnned in, etc. I guess the SM is a good example so we you can know what I'm referring to ... those high, what-look-like-odd-angle-piece-of-slate stuck in the sight base ... Would someone explain them to me? I'm not knocking 'em, they just look odd to me and I've never been given any information about them. Obviously, they were, "tops," at the time. Clue me, please? Over?
