Hi everyone!
There is a slight problem with my Arken EP5 scope, and I need some advice on how to fix it.
This scope has a Zero Stop feature. By default, it lets you tighten a screw, which then is blocked by a ridge on a plate under the elevation cap, which prevents you from dialing elevation under your zero.

The plate with the ridge is locked in place by three set screws and you’re supposed to be able to adjust it if you for example want to set your zero stop to -1 MRAD of elevation (like in this video I found online https://youtube.com/shorts/gqDuAySoZoI), which I’m trying to achieve here.
The problem is that when I unscrew those set screws even the whole way out the plate doesn’t move at all. My theory is that this is because some threadlocker (there was some of it applied on one of the set screws) may have gotten under the plate and glued it all together.
So, my question is this: can I put a drop of some solvent (for example acetone) inside where the threadlocker may be to try to dissolve it or will it damage the scope?
Unfortunately, I do not have an option to send it to the manufacturer to get it fixed from where I live, so I must deal with this problem myself.
Thanks!
