I have a PKS 07 with the elliptical range finding and dot reticle mounted on a VEPR 7.62x54r 16 inch rifle that I got in a trade.
I have been unable to find any info on how it operates or how to use the elliptical as a range finder.

Does any one know where to find info or how to use it?
I read someplace that a human torso will fit in the outside edges of the elliptical but it was never confirmed or explained.

I got one of these about 10 years ago and haven't been able to find much at all about it.  I suspect these were not widely available, so there isn't much info is online.  I need to do a search again.  But I have suspected the oval is a range finding tool that the width is one range and height another.  Again, just a guess.

I bought my scope and it showed up with a 'broken' reticle.  The seller was no help and told me to file a claim with the shipper.  I did and got a full refund, plus I got to keep the scope.  Something inside got messed up as the reticle is just a blur except for at a very narrow viewing angle.  If you tilt it 1/2 degree in any direction it disappears.  I'm pretty sure they ship it that way as it was packed decently (bubble wrap inside box) and I can't imagine shipping would damage it.  So it basically sits in my garage as I don't know who would fix it and don't really have a true need for it.
