No worries, I'm so far out of
my lane that I may as well be off-roading. :-/
My goal with my optic setup was (1) light weight; (2) etched reticle with adjustable ocular and (3) low power fixed magnification. For better or for worse in the upcoming zombie apocalypse, nothing else mattered to me. So I got all three of my main priorities met with a
FX-II Ultralight 2.5x20mm scope (how weird is that on an AR?) in a
Daniel Defense mount, the scope and mount together weigh 12 ounces. My old eyes can see the Fuddy duplex reticle just fine, and if its too dark to see it, I resort to white light.
FWIW, the scope has worked out amazingly well for me: crystal-clear optics, long eye relief and a forgiving eye box. It's allegedly tougher than nails (a well-vetted dangerous game rifle scope). The mount seems quite rugged without knobs, nuts or levers sticking out. Best of all, my limited processing power is not tasked with decisions on what power to select or how bright to adjust the dot (or reticle). It's one of those point-and-shoot affairs for the simple-minded.
After experimenting over the years with a variety of RDS and LPVOs, it's the first time ever that I no longer have any desire to further experiment with optics for this rifle. But then again maybe that's simply because I spend all my money on flashlights now.
