Home Forums Hunting & Shooting AR and Tactical Rifles NcSTAR scope problems

I hope this is the right place to get some answers.

I have a NcSTAR 3-9x42 Rangefinder scope on the AR. I know they are cheap junk & so on so lets skip that part.

The issue is that it will zoom from 3.5 to 6 easily by hand. If i turn it extremly hard it will turn to 3. No matter how hard i spin the other way , it will not go past 6. I removed the eye piece and took a peek inside & knew i needed to put it back on before i really screwed it up.

Should I grab some pliers & force it? Do any of you guys know what could be making it bind?

Thanks in advance
