I've tried several fixed 10's, Jay, ranging from cheap Chinese junk up to an MTC Viper. The Viper would be all you're looking for, but it's expensive, heavy, and long. If you can live without AO, I can highly recommend the Bushnel 3200 Elite 10x40, sometimes listed as the Elite Tactical. I have one on my R9 and really like it. I readjusted the parallax for 35 yards, gives me a nice crisp image from somewhere around 15-20 yards out to farther than I'll ever shoot it, call it 80-90 yards. At 10 yards, the image IS fuzzy, but that didn't save the starling I whacked yesterday :-). Has a nice, fine mil dot reticle, some pretty beefy target turrets, and outstanding optics. Here's a link:
