rear sight

JD,
Yeah, I recognized the ramp problem within 10 shot on my first r92. The group got lower and lower until it finally bottomed out.

A daisy bb gun LOL. Wish I had one I could rob the ramp off of.

The Skinner front does come in three different widths for ramps or dovetailed barrels. For the Rossi barrel the 3/8" wide for ramps may actually fit more attractively. I have 1/2" wide ones for dovetailed barrels but I like to soften the corners with a file before installing them. Ramped front blades fit nicely and look smooth.

The rifle length #66 Marbles will probably fit your barrel. However, keep in mind the elevator high end fits in front of the buckhorn and the receiver end of the elevator now comes with a short tab and raised nub to grip for adjustment. It extends out from under the buckhorn a bit but shouldn't interfere with your receiver. If it does, a quick swipe with a dremel would lop it off and not cause difficulty in adjusting.

Williams or Marbles offers somewhere a formula for measuring sight height relative to bore centerline. If the Marbles buckhorn doesn't land in the exact same place as the stock buckhorn you will want to know how high it is from bore centerline. Basically, with a calipers measure the barrel OD where your current buckhorn is, divide that by two, then measure the height from the top of the barrel. Then repeat where the Marbles will sit. For reference, the #66 measures 2.55" from center of dovetail to the point where the buckhorn rests on the elevator. From your photos, it looks like you may need the standard/low model. Especially with a tapered barrel.

Let me know if you need the measurement of the shorter #63. I have one in my parts bin too.
