I also have both, and concur that the S&W is a very good gun, and a good value. The S&W should hold up fine with the type of use you intend, and it is also accurate. I put a Aimpoint red dot sight on mine, and that set up would work well for what you are looking to do... This being said, if I were to have only one AR, it would be the Colt.

If you have the extra money, I'd go with the Colt, as it is the best quality production AR you can get; buy it once. Either way, I hope you enjoy your new carbine. Just my two cents...
