AR Recommendations for a LMG/rifle guy

Hi All,

I'm playing around with some builds and I think an AR would be a better option than my typical LMG/rifle setup. EB is out because I've never tried the raid and likely won't have that opportunity. I crafted a FAMAS (like the high ROF) but that was basically a dart board, pick'em. So for you AR gurus, suggestions?

Thx
