OK, I have narrowed down my choices to a Colt 6920 or a sig 556. I will buy one of these two rifles. I have handled the sig in the store. I have never got to mess with an actual colt, but I have had other ar-15 carbines to mess with so I get the basics.

ANyway, I am looking for a little input to help narrow down my decision....which would you want and why?
Also, would the 1 in 7" twist on these two rifles have a negative effect on using XM193 (55 grain), which is what I will primarily be shooting.
