A friend of mine just purchased a model 54 with a Leepers scope. He had asked for the scope to be mounted, but it came unmounted.

So, we went ahead and mounted it, but he says he can't get the scope to go any higher than six inches or so below the bullseye.

In other words, he's maxed out the elevation, and can't get the scope to aim any higher.

Any suggestions? Does he need to shim the back of the scope? Does this sound familiar at all?

Thanks.

RWS airguns have a history of barrel droop. I would get a 1 piece drooper mount which is higher in the back to compensate for the droop. That should give you more scope adjustment. Shims will do the same thing but the 54 can be hard on scopes and mounts and i'm not sure it will hold.

I would HEARILY recommend the Beeman one-piece adjustable mount. It ain't cheap, but it is VERY solid and will do exactly what you need. I've used one on my RWS 52 for about a year now with a couple of different scopes, and I'll never use anything else.

if it is 10 meters then being 6" low is not such a big deal but of course if you are maxed out on elevation that is another matter. that scope won't survive that way.

first thing you want to do is optically center your scope. the quick and dirty method is to count the total available clicks from botton to top. devide that in half. bottom out your scope then count clicks of elevation until you are in the middle of the range. do this for both elevation and windage. there are other methods but cumbersome. once yo have centered the scope and it is leveled side to side sight a target at 30 yards. shoot a group and see where it is is in relation to the bullsey. you will probalby still be low. the UTG/leapers mount is available in 17", 20" and 0" droop comp. use the least amount of compesation to get you closest to center without adjudsting your scope. if you are not very low just shim the mount. if you use the leapers mount you will need low UTG space age mounting rings for piccaniniy rails (weaver).

i have heard things like the leapers mount will be way off to the left. this is not always the case but i know Ray had that problem but it may have been unique to his gun or the one that he got might have been defective. mine was dead on for windage on my 52.

RWS designs in droop for their air guns. Some people say they have found ones without, but it is not the norm. One thickness of the plastic case the rings come in usually does the trick (between the scope and the rear ring). I have found the best/cheapest mounts are the Leapers one piece mounts. They hold well on high powered springers and don't cost a lot. You can get the scope at the height you want as they come in 3 heights.

If you go with the Leapers droop mount, be aware that they are sufficiently high that even with low rings, the scope will be mounted higher than regular high mounts. You need a rectangular shaped stop pin in the rings to go with the rectangular aluminum cutouts on the mount to keep from wearing away the mount (like the Leapers ones they provide with some scopes). Larry has found a Leapers ring that has such a stop and I have found B-square rings (that I think are better as they have a bigger stop pin surface area) - but I never actually had these problems with a Leapers conventional one piece mount!

Thank you all for your suggestions. I will pass the information along to my friend.

on a regular 3 bolt 1 piece leapers scope mount.I grabbed a bunch of those credit looking cards on the counter of my local McDonald's then cut 3/8" wide strips by 3/4"long hand form it and lay one in the bottom of the rear scope ring.Bolt the scope back on and your good to go.These seem to be the perfect thickness shim for 48/52/54 Diana's.
Not to high not to low your elevation knob will be pretty near center in turns .
The cost is free to!!!

Air Guns Create Questions????
Together we can write the answers!!

mount. it is .093" difference between front and rear of mount. on my stutzen 46
which actually has more droop than my 52 i was able to cancel most but not all droop with .047 of shimming but i am not optically centered at 25 yds. 125 clicks down would be centered but i am 92 clicks down from top out. i used shims with 1/3 in the base of the mount between mount and gun and 2/3 in the rings. without shimming i had very little elevation clicks left. i need 16 to compensate for drop at 55 yrds. i would prefer to have no shimming at all so i may take a UTG drooper mount and modify it for the stutzen. i will have to grind off the front shoulder since the 46 rail is the whole length of the receiver. this will give me more droop than needed but then i can use one .015 shim in the front ring. this should get me optically centered. this is better than two in the rear ring and one under the mount i think. not as hard on the scope tube. the stutzen recoil is not as strong as the 52 so the mount should hold with just the one stop pin and those three bolts on the UTG mount. i use 25 yds as my zero bcause that gives me the best trajectory over the FT distance of 10 to 55 yds. i only have to worry about hold over or elevation clicks and not have to worry about both hold over and hold under or plus and minus clicks.

Just received mine one week ago, I have a Model 52 .22cal with 4-16x50 Leapers scope and one piece five(5) bolt clamp mount I bought on Ebay. I did not experience any barrel droop, but plenty of scope shift issues. I degreased all contact points and this setup has been good for over a year and 1000 pellets. The Model 54 on the otherhand has barrel droop when I tried to site her in at my indoor range and ran out of elevation on my Bushnell Banner 6-18x50 scope. I ordered from PA the dn460 droop compensator mount and a pair of UTG low Weaver rings. I know this will solve any droop issues but I am concerned with scope shift issues, the Model 54 is notorious for scope shift. I hope this holds tight. Will keep you imformed on later posts.

Shooter,

The Leapers UTG low Weaver Rings have a rounded stop pin that will round of the top edge of the droop mount and cause the scope to shift. You can see the pin in this picturehttp://www.pyramydair.com/cgi-bin/accessory.pl?accessory_id=2449

I got B-Square Interlock rings, which have a rectangular pin (which is what you should look for to mate with this mount. If you choose to mount what you already bought, you should at least blue lock tite the threads on the pin, position each ring so the pin is snug against the back stop, and tighten down really good. It probably won't work in the long run, but it will be a while before you search for this post to see what rings to get....

Thanks JC for the heads up, but I went with a different style of UTG low Weaver mounts

These have a square slot to fit into the Leapers droop rail

they work well with a picatiny rail. just make sure you butt the stop up against the cross ridge on the rail. also, make sure you have the right size allen key since they can be stripped out if you use one that is too small.
