my new underlever is amazingly accurate with FO sights but with several scopes i have tried,
its around 10-12" low @ center elevation adjustment and 5-6" low at max "up" adjustment.
last resort is to let MM bend the barrel, but he says to try a few things first and a droop
mount is one of them.
i have seen the UTG droop mount that appears to be fixed, non adjustable.
then i see others that are adjustable.
i even have read here where there are adjustable rings or to use shims under the rear ring.... :o but won't that distort the scope tube ??
your help is much appreciated, thanks

You've got a can of worms here. Droop compensation may be achieved via a dovetail to Weaver adapter. I understand the XS-46 has a dovetail on the receiver and comes with an adapter so you should be able to remove the included adapter and replace it with a droop adapter. The idea is not to add a droop adapter to get perfect elevation but to get it within a range with which you can work.
I am not a big fan of adjustable mounts though I've only tried one type. They do work and they are stable I just don't personally like them.
I am even less in favor of shimming scope rings as it can place undue stress on the scope tube. You are putting a slight angle on the tube but the mount angle doesn't change. Bending of the scope tube can result.

yes i'm wanting to remove the supplied adapter and install a decent droop adapter
like the utg 11mm to weaver droop adapter which is fixed and non-adjustable to get me in the ball park of correct elevation adjustments.
i'm a PB'r veteran of 60+ years and realize that scopes dont need any ring mods... :o
thanks

I have a Diana 48, which I believe has zero droop. I had to crank the elevation down to get it on target. I got the Leapers mount. I chose that one because it has two scope stop pins which line up perfectly with the holes in the dovetail - T06 trigger.
The Leapers should work perfectly for you.
If I ever get a T06 Diana 34 with droop I'll move the mount and get an adapter without droop compensation.

i understand, my son has a rws350 and it was the same way you described with yours.

well i picked the worst scope i had laying around and put a shim ( a broadhead blade ::)) under the rear scope ring...and tested.
with about 75% of the down adjustment....it worked !!
i think the scope is confused the same as i am :o
this will put me frog'n this weekend with the underlever until the compensation adapter arrives end of next week...i hope.
thanks Thomas for your help.

BKL makes both a drop compensated mount (24 MOA), and adjustable mount, and their stuff is first class.
