Re: SN-3 3.2-17X or S&B 3-12X50 PMII Military
I've owned both, the S&B is really nice but the USO has some really great features. And also some really great reticle choices. If I had to chose between these two it would come down to exactly what I'm using it for. The P4F is a little small when using all the way down if you do a lot of low mag stuff (hunting in thick forest etc.) But I still find it nothing to complain about, some people do. The EREK knob rocks, plus I like the ERGO too. Not nearly as finicky as a side paralax if your changing ranges quickly. But all and all I rate them pretty damn close.
There's a big difference in mag there. Do you need the extra 5x of the USO? If not, go S&B. While you can shoot 1K perfectly fine on 12X, You might want to consider the 4-16x in your comparison instead. I'm no "expert" but its just a suggestion. Either way, you'll be dissapointed with neither. And yes, S&B glass is phenominal, but USO is very good. i only mention this, because when buying a top tier optic, the glass is always going to be good, the features(turrets, reticle, tracking repeatability, etc.) are a more important consideration at this level. they will all have good glass, but does it do exactly what YOU need it to do?
