I believe you would be more than satisfied with a 16" Barreled AR.
Bottom line if you purchase a good quality AR Rifle you will have no problem with the 16" Barrels. Either in CAR Length or Mid Length. I prefer the Mid-Length Models myself for several reasons. One being if you do get a Quad Rail for the Rifle you have much more mounting surface on the Quad Rail for Lights and other accessories. Some of the good rifles are Rock River Arms, Stag Arms, Daniel Defense, Spikes Tactical, LMT (Lewis Machine & Tool) CMMG for just a few. These rifles are built at a bench not assembly line produced. The FTF Members can certainly assist you when the time comes for your selection. And can even advise if you would want to build your own rifle, of the best ways to go about it.
