I have a Diavari (C?) 3-9x on my old Sako Forester as my primary hunting rifle and it's certainly a decent enough 'scope for around these parts but I have a wealthy friend who has just put Schmidt und Benders on a couple of long range AR's and there is simply no comparison.
The whole optics thing seems to be neverending. I think this forthcoming little Leupold will do for 'coons in the back 40 though.
