Bushnell 2.5-16x50mm side focus question

I'm considering a used Bushnell Elite 2.5-16x50mm with mil-dot (.  It also includes an aftermarket sidewheel focus attachment.  We use these a lot in air rifle field target for more precise range-finding which then helps us calculate holdover and/or elevation clicks.

The issue is that the sidewheel was attached using JB Weld.  This is not a problem in and of itself since I will be using the sidewheel.  However - my concern is if the scope ever needs service or repair.  I don't know if or how I can get the AO knob off.  Is it retained by a screw or by something internal to the scope? 

I realize that I'd probably have to trash the sidewheel if it ever came to that but I can live with that.  Mainly I want to make sure that by performing this JB Weld mod that the scope knob or the scope itself isn't irrevocably ruined.

I've been offered the scope for $450 which is why I'm considering it - at least $100-125 less than new and the custom sidewheels aren't cheap to have made.  Yes this one is busted up a bit (it was cut to accommodate magazine loading) but will still rangefind at the ranges I need.

Thanks for any and all advice!

I agree - JB Weld seems a bit drastic.
