Damn, guess I'm on the spot now. Off the shelf, I feel Colt is one of the top MOA guns I would also put LMT right along side of Colt but they are more money and I don't feel you will gain anything in accuracy over the Colt.
The 6920 and 6940 both have the 4 position stock which is nice for the smaller shooters, such as kids,grandkids and wives, a plus in my book. I like the handguards better, I do prefer the 6940 over the 6920 due to the full length rail which affords the option of setting it up for various optic's along with room for night vision. I feel that both of these Colts are priced right and will hold a good resale value if and when you ever choose to sell either.
I have run 1000's of rounds through both of mine and never had a problem with either gun.
I have also had outstanding results with RRA.
I'm sure Mackay and rost will chime in with their opinions and they are very savy when it comes to AR's and what they feel is best.
Whatever you get will only be the beginning
