Throw some opinions at me please... I am about to buy my first ever AR type rifle. So what do I go with? I am leaning towards Bushmaster just because a cop buddy of mine (who has shot and handled many AR variants) says they are the best of the type but I am a Colt fan from way back. So between Bushmaster, Colt, DPMS, Remington R-15 and all the rest, which is the best? I know that Remington, Bushmaster and DPMS are all owned by the same parent holding company so I am assuming that one between the three brands is the bargain basement version.
