I completely agree about the reticles. Anything with more than 1 mil marks just seems too busy for me at this power level and what I'll use it for. I've been thinking about the SWFA SS because the reticle looks like it would work with or without illumination like you said. I really like the USO SR4C, but it's just a little too expensive for me.
General question for anyone with some time behind a 1-x optic. How do they work for home defense? I would love to put a vortex 1-6 on my 16 inch recce and have that be my do it all gun from shooting at the range, to hunting, to carbine classes and home defense. However, if it is dramatically inferior to a red dot in the home defense role, I'm going to think about getting a red dot and maybe a little bit cheaper variable power scope, or maybe building up a second carbine over time if I'm trying to put too much requirements on one gun.
