imho....
I hate an AR10 platform. Army. An AR is supposed to be small light and sexy. a 10 ain't none of them - again, imho.
second - say what you want about the 'need' for a FA. While I will whole-heartedly agree they aren't needed (at least in a Civie model, under NORMAL circumstances...), I HAVE to have one, or in a SHTF scenario, lack of one would get me killed. Reason: I learned all my immediate action drills WITH an FA. W/O an FA, I totally screw up the IA drill and nearly rip my inner right forearm to shreds trying to find it - at least 3-4 times in a row! When I went to buy my first 15, I was flabbergasted by a S&W Sport (no FA). Old 'Nam vet sales guy watched/laughed/said 'here, try THIS one.' THIS one was a Wyndham WITH an FA. AH!!! all the old training came back and worked flawlessly.
I feel very competent with a SA revolver for defense (shot one all my life) and I also firmly believe "I" need the FA in AR platforms, due to my training and muscle memory.
