Elevation topped out

 

+1 Thumper is correct on bending your barrel upwards Which is no big deal.

Your other option is...If yours is a 30mm scope tube...

THIS IS REAL CHEAP NORMALLY SELLS FOR $30.00 OR MORE.

I shimmed the scope on my 392 using two layers of milk jug plastic. I moved the point of impact from ~5" low at 15 feet to ~6" high at 20 yards. I guess I could have gotten away with just one layer *shrugs*

Can use beer or soda can as shim.

I used two layers of soda can for my diana 48. Worked like a charm.

I originally was going to use a Pepsi can, but knowing my luck, I would have sliced my fingers up with the sharp metal, so I used the plastic jug, which isn't much thicker than the pop can. I really didn't know what I was doing and was taking a guess based on the recommendation of using pop cans as a shim. I DID NOT expect two thin pieces of plastic would move the POI that drastically.

When it comes to tinkering, I'm more of a "Tim the Toolman" rather than an "Al Borlan." (Tool-TIme reference) so I tend to mess things up rather than improve them...this time I had a rare streak of luck and things worked out well.
 
I would take out one layer of that shim and just wrap the other with electrical tape.

Any kind of masking tape can work too.

I thought about removing one of the plastic strips, but I've already got the rifle dead on at 20 yards. And (I THINK) the plastic might compress a bit when the rings are tightened down (finger tight) so it may not be as thick as I thought. Too, with my luck, if I mess with it again, I will screw something up LOL.
