Have an AV 4-12x50 on my Sako M75 Hunter Stainless .270, long action, been mounted for 10+ years and has been bullet proof. Barely, if ever, adjust it year to year. Would not hesitate to buy an AV at right price. Also, have a 3-10x42 on a L46 Riihimaki .222.. I think they went to the Z3 nomenclature when they introduced the Z5 series?
