I am interested in the ACR and have read everything possible on them. I work in Law Enforcement in South Eastern Pa and everyone I talk to says to go with a Colt or other high end gas piston system. I am going to a gun show this weekend and will be buying something. Just need some input on guys who have both. I also have to consider the fact that my wife is 5'4 about 110 Lbs. She is also a cop and will be shooting the rifle as well so weight might be a factor. Any imput will be a help.
