I know what I am looking for probably doesn't exist, so let me clarify. I want a good all around rifle. It must be capable in most situations, but obviously I hope all I ever do is plinking. I've narrowed it down to an AR15 Performance build in 6.8 SPC(18") , or a RRA LAR-8(16" or 20"). I know about ammo availability and prices. I looking for overall reviews and insight I may not have considered. Also, I'm 6'8" and 275lbs, so a bigger rifle, or recoil, doesn't bother me, and I'm looking for longer barrel lengths to make it more comfortable to shoot. Tell me your thoughts.
