I have a chance to get a Colt AR15 Accurized Rifle CR6724 for $1200.00 and was wondering what your guys opinion is on that model and if it is any better than any other ar-15 out there for less money? This is my first ar buy so I'm not up to date on what is good or not in the ar world. If you guys think it is a good rifle and worth the extra money than I'll get it.
