Optisan EVE

Got an Optisan EVE 4-16 scope on Black Friday sale. Nice scope. Solid, nice glass, great reticle. My complaint is the parallax adjustment is very stiff and will not turn without really gripping it. Likewise, the cap for the battery for the reticle won’t come off. I have not tried tools yet, but I can’t make it budge with my hand. Anyone else experience these issues with this scope?
