I just unscrewed the front ring on mine and fitted a butler creek to stop it moving. Others sometimes fit an 'O' ring in the gap.
Hi got a Bushnell 10x40 elite 3200 that i'd like to have reparrallaxed to 25 yds for HFT - can anyone help me out??
Cheers

yup. I do the o-ring; tightened up against the o-ring really tight, stuck a bit of tape around it to stop any chance of movement, and then put the butler creek on. Good scopes for the money, I've a few of them.
I've unscrewed the front ring by around 2mm - now the scope focusses at around 7ft???
Not really sure what i'm doing to be honest - have i done it wrong???
Daz
Yep tried it again and i don't know whats happening with it but it now focusses at 10ft with a tiny gap
Bugger - looks like i've broke it
Daz
...more likely the lens carrier is moving independently of the outer ring...try loosening it, you may be pleasantly surprised... I've done 5 of these with no issue.
Nope the lens carrier thing isn't moving until i move the outer ring???
Daz
then I'm confused Try putting it back to where you started and see where it focuses ?
Hi Daz
Not wrong exactly; you've just wound the front ring out too far. Wind it back in.
I re-parallax like this.
Set out a target at your chosen zero. A simple crosshair "+" works well.
Adjust the reticle so that it's crisp and clear.
This next bit is usually easier with the scope removed from the rifle, and using a beanbag.
Wind the front ring out A BIT AT A TIME until the target is in focus. Now move your head about a bit [but
without moving the scope, of course] and adjust the front ring a bit at a time until the reticle stays
stationary over the +. You have now removed parallax error at that range.
Butler Creeks or whatever to lock, and job done!

Have wound it in fully until the outer ring is tight and it now focusses at around 15ft
Wish i hadn't touched it now
Might have to use it as a .308 target
Daz
Did you buy it new Daz ? What range was it PX'd to originally (should be 100 yards). I'd wind it right out and then back again, see if anything changes.
Wind it out til it comes out??
Won't that let the nitrogen out??

Hi Daz
Look again at Jon Budd's 08:58 post. I think that that's the only explanation.
Try this. Unscrew the outer ring by say one turn.
Then, VERY carefully, using something that won't do any damage [ wooden or plastic toothpick, cut-down
credit card, or even your fingernail ] engage in the lens carrier slot[s] and try to move the lens carrier
independently of the outer ring.
If it does move independently, then that's good! You won't need Butler Creeks after re-parallaxing!
HTH h j [I REALLY wouldn't wind it right out !!]

I can't get the inner thing to move at all - even pushing on it.
Looks like the "quick job" has knackered my scope
