How to re parallax Bushnell elite tactical

Never have done it myself but I've read that it can be done, at least on some scopes. Seems it involves removing an outer ring around the objective lens and then screwing the lens/holder in or out.

I have done it myself on a few scopes in the past with complete success. 

But the lock ring of objective ring of this scope is too tight that is why I am unable to adjust it.


 
I have the right tool for the job and have adjusted several scopes. But I have one scope that the ring refuses to budge. Don’t wreck your scope if it doesn’t turn with minimal effort with the right tool. The next owner of your scope will be much happier living with the 50yrd minimum rather than having the scope look like a rat chewed on the objective.

Please share the pic of the right tool.
 
Finally I am successful. 

Without any tools, just by strong hand grip, I unscrewed the objective lense carriers around 3/4 round.

Now it's parallax error free from 27 yards to 125 yards, from minimum focus ring to maximum. 

So I can't shoot at 200 yards and beyond. Things get out of focus after 125 yard but as I have to use it for pcp target shooting, it's fine for me from 27 yards to 125 yards.

Thank you all.
