Green Fiber-Op front sight - Round barrel

3-Stars (middle). Great sight for buckhorns- quick fix on target. BAD: the Dovetail 3/8" cut is not ROSSI-style. Rossi is a 'tight' 3/8"...you indeed have to punch the old one out, but this thing slides in and all the way through- and just catches on the far left (ala dovetail). You need a sight cut bigger or change the bevel- for the Rossi's is a flatter cut of an edge. Just not an R92 45LC Sight...Rossis' are a funny gun. cheaper in price, but you pay for it in the backend (understrength screws, bad milling, etc.). Bottomline, a standard Hi-Viz front site won't adapt for a Rossi. Great site (better with the rear green bucks), but this particular one is just off. I'll try it on something else.
