Things I liked: I have a Mod. 36 made in 1998 that has lots of droop. This was a perfect solution to that issue. Works like magic. This gun has always been very accurate, now my scopes don't need shims.---HOORAY
Things I would have changed: nada
What others should know: low to med. rings will work better than high ones for the most part, unless you get the UTG scope with 53mm obj. lens.
Things I liked: Nice piece of hardware but did not work for my 1980 something model RWS DIANA 45 MODEL. Scope ran out of down adjustment before it could be zeroed. I actually turned it around backwards and it worked better that way. Now had to use quite a bit of upward adjustment but i was able to get it zeroed in.
Things I would have changed: In description, it should let RWS DIANA model 45 owners know that droop compensation may be to much depending on which model year thier gun is.
Things I liked: fixes barrel droop on Diana 34 22 cal
Things I would have changed: nothing
What others should know: Bought a new Leapers 4-12 scope that was set at factory Zero . Using a leapers mount it shot 17 inches low at 30 yards and 3 inches left. As I did not want to try to adjust that much drop on a new scope so I bought this base and a set of weaver bases . Now it shoots 3 inches high at 30 yards , 3 inches right and is in my comfort zone of scope adjustability

What are the numbers on the top of the rail for (02, 04 .. 10, 12)?
Will this fit a Benjamin Trail NP Nitro Piston?
No it will not
Will this fit my 1980's Beeman 250, I think it is the same as a Diana 45?
You would need to confirm that the 250 is in fact the same and that it has the elevated dovetail rail on it. If it does, you should be okay.
