This little tool allows you to adjust the front objective lens on fixed parallax scopes to more airgun-friendly ranges.  You can also make an AO scope focus down to shorter ranges, (but your yardage markers WILL be off.)  Typically, for shorter ranges, you want to move the front objective lens OUT of the scope barrel.

Heck, I've even made non-AO scopes into AO, by backing the front retainer ring off a little, then drilling a 1/16" hole thru both the retainer ring and the lens carrier ring, then tying them together with either a tiny screw, or even a piece of toothpick, then trimming it with a razor blade, and a dot from a Sharpie.  Looks factory, but again, no yardage markings.  You have to rely on the head-bob technique and good-old eye focus to determine when it's right.  But really, once you spend some time with it, it'll become pretty easy to change range on a non-AO scope.

Hey, thanks!  That looks like a pretty-cool little tool.  The price is pretty-amazing, assuming that it holds up over time.

Safe and Happy Shooting!

Its pretty simple but substantial, and it also comes with socket-head capscrews and an allen wrench if you really want to crank it down!  But the thumbscrews seem to work just fine.  And its a pretty low-stress tool in its intended use.

That process has been around for a long time. Keep in mind that once you remove the front ring and the objective lens, to access the ring behind the lens, you have blown the dry nitrogen fill. If you reassemble things in a plastic bag filled with dry air (or leave everything in an air filled bag with several desiccant packs), you can help prevent problems.

On the few that I have done, I never actually opened the tube.  The objective lens is in a carrier ring that is threaded into the tube, and on the ones I've done, they were all "sealed" with silicone grease.
