Need a little help here- just picked up a vintage Unertl 6x Small Game Scope. The literature on the internet says the focus is adjusted with the "Erector tube". Anybody know what that is? Idon't see any way to focus this nice old scope- just being stupid, probably, since it all looks complete - the objective lense has a slight bell but seems like part of the tube, and I hate to twist it too hard until I figure it out. Any info would be appreciated.

The occular (eye piece) should still screw in and out...should be threaed with a lock ring....this would set the traditonal focus.

Don't try to screw the objective (the front housing) out...doesn't work that way.

Along the scope tube you'll see a little screw and washer. IF you were to slightly loosen this screw you could slide it back and forth just a little bit...the screw is what holds the erector lens system in place inside, and by moving it just a bit, can set the paralax..but be sure to just loosen the screw, not take it out. Not something you do often, so set it for some reasonable range and leave it alone after that.

Ahead of the occular there is a knurled ring..usually it has the scope's power stamped on it. HAs two set screws on the ring. This ring levels the cross hair in case the blocks aren't dead level (which is pretty common).

------
Setting paralax (sliding that little screw/erector lens system):

1.Get the eye piece set to give a sharp image of the cross hair.
2.Point it at a target at 75 yards (or whatever range you picked).
3.Set the rifle on bags, cross hair on the traget, so it is stable without touching it.
4. Move you head/eye aroung as you look thrugh the scope...if the cross hair moves off the target, have paralax at that range.
5. Fiddle with the erector as outlined above and try step #4 again.


Eventaully you'll find the spot whee the cross hair stays plastered to the target even while you move your eye around the scope's field of view.

Unfortunately it can only be perfect for one range...but it's close to perfect for a good distance after and a short diastace before that range...so lets say you set it for 75 yards. Would be nearly perfect out to 100 or as close as 40.

Ribbenstone: Thanks very much for the exceptionally useful info. I see you're from NO- we're from Gretna- hope all is well with you and yours after Katrina.

Most of the guns were lost to 35 days of salt water soaking...including my 6X Unertel like the one you wrote about. that one got bent into a "c" by the car that swept theough the back room, then rusted to an almost unrecognizable mass. A LOT suffered the same fate....stripped some to the recievers, tossed the parts, and burried the recievers.
