I searched but couldnt find a thread on this. I just learned how to change the Parallax on a scope myself (did my first 2 yesterday) and was wondering if there was a specific target or method you used when changing yours. I just used my archery target in the backyard but it was a pain.

Thanks

Robert

I got it. I just went through the process with Leupolds Customer Service and they stated "that's how it's done" and "it will not void your warranty" so I am proceeding with caution because if I purge the gas I WILL have to pay for that repair but so far on one Simmons,Bushnell and Leupold VXII I am good to go.

Use at your own risk....

1)Take a strap wrench or your hand and twist off the Objective Cap.

2) This will expose the Objective lens carrier (The black threaded section)

3) Set a target at the desired distance and the scope on a solid rest. CHECK FOR Parallax.

4) In order to shorten the focus turn this piece counter clockwise with your hand and to increase turn clockwise. WARNING THERE IS NO STOP ON THE LENSE CARRIER IF YOU SCREW IT OUT TOO FAR THE GAS SEAL WILL RELEASE.

5) Only screw 1/4 revolution and check for Parallax. Keep doing this 1/4 turn at a time until the image is stable when you move your head.

6) Hand tighten the Objective Cap and you're done.

That's it....The Scope is now set for the desired distance.

Please enlighten us to the process. I have a Vortex Viper that I'd like to set to 50 yds.

Sean,

That's basically it except with the Leupold I had to use a Strap Wrench. The Simmons and Bushnell I removed by hand. None were attached with loctite and the Lens Carrier can be screwed by hand.....do not use a metal rod or file like this guy suggests.

Basically you are turning the lens carrier just like with an AO scope....the obvious difference is that you don't have the nice numbered ring. Also it only takes about 3 minutes from start to finish....these guys make it sound complicated for effect.

Since I posted this I've had people PM me that the Erector controlled Parallax and that the Ocular adjustment controlled it.....neither is true. The distance that the Objective lens rests from the Ocular controls Parallax.

Robert

Why would you post this if you didn't want to explain how it was done?

Don't really see any difference in possibly ruining a scope via PM or post.

Thank you for this great tip, Bruzer. A agree with JM that you shouldn't be so shy with details. I imagine there are plenty of us with extra centerfire scopes that we'd like to put on a 22 and I know the first one I do won't be an expensive one.

John,

In my PMs I was providing my phone number so that I could walk them through it verbally. I walked 3 folks through it yesterday with success. I'm making a video this weekend that I will post if anyone wants to see the process.

It is really simple and the risk of ruining a scope is minimal in my opinion. At worst you would have to send the scope in to be charged with gas and that would take a monumental blunder on the behalf of the person performing the Parallax adjustment.

Here's a link on how to do it.

http://www.rimfirecentral.com/forums/showthread.php?t=94809&highlight=objective

I've adjusted the parallax on four or five of my scopes. It's no big deal.

One tip I'll give you is if the front ring cannot be loosened by hand try some duct tape. A full width size piece wrapped once or twice around the ring, then flip it over a 1/2 turn, wrap some more, wrinkle it, wad it up and then another couple of wraps. The object of all this is to have a big wrinkly wad of duct that you can grab on to. It works and you won't have to buy a strap wrench.

The black threaded Objective Lens Carrier is the piece that you turn Counter Clockwise to shorten the focus or clockwise to lengthen the focus. The only difficult removal was the Leupold so far and Fishheads tape trick works as I just tried it in lieu of a strap wrench.

Note....Every scope I've tried so far will focus down to 40 yards. I didn't push it past that point.

I bought a Nikon Pro Staff 2-7x32 to put on of my .22's. Very nice scope for the money. I tried to adjust the parallax down to fourty yards - no problems with that - but the carrier stuck out past the body of the scope and it wouldn't allow the ring to be screwed down all the way. It left a big gap between the body and the ring which I just didn't like.

One other tip. After re-setting the parallax - re-adjust the crosshair focus with the occular lense. In a couple of scopes it seemed to have an effect. I could be wrong though, if does actually have an effect or not. It's worth checking anyway.

Could you fill that gap with an O-ring? Just a thought....

You could and it would probably work just fine - might look a little funny though. I gave up on it for the .22 and put it on my muzzleloader instead.
