Hey guys I have an opportunity to buy a colt 6920 ar15 for 1050 otd. I was also looking at the smith and wesson m and p sport model. In your opinion, is the colt worth 300 more really or am I just sipping the kool aid? This will be my first ar15 and buying pretty much for 100 yard range shooting and a just in case rifle. Already owned aks but finally want to take the ar plunge.
