[QUOTE="Chrismadrid, post: 134714, member: 4416"] Not sure if this helps but This [img]http://www.telefonica.net/web/vcs/IMAGESFORPOSTING/6-24 2.jpg[/img] looked like this [img]http://www.telefonica.net/web/vcs/IMAGESFORPOSTING/6-24 3.jpg[/img] inside. Nº3 most definitely was the reticle - mounted upside down of course and nº4 the erectors - it was the precursor of this [img]http://www.telefonica.net/web/vcs/IMAGESFORPOSTING/blackrussian.JPG[/img] in whose development I was actively involved. POI shift in SFP zooms is a known fact of life. An expensive scope should not exhibit much - maybe 1 click or two max. I've seen TASCOS shift 10MOA. It is documented as more common on VXII than VXIII Leupolds. As an aside sloppy sidewheel and AO mech's as well as sloppy ocular adjusters can cause POI shift too - not just poor zoom controls and erector cams. [/QUOTE]
