Picked up a Colt Model 6920 today. My question is I seem to remember reading a post regarding that Colt no longer makes the "6920 model" but instead makes the "M4" model. Of course I can not find that post now Just curious what I bought, not that is matters a whole bunch. So: 1. Is their any difference between the "6902" model and the "M4" model produced by Colt? Or just the name? 2. Was the "6920" ever roll marked "6920", or just M4 as this one is? Here are some pics of what I picked up today: The box is marked "6920" The rifle is marked "M4" Did not get "capitalismed" on the price thank goodness. Impulse buy. Offered to sell it to my father in law for cost but he does not want it. Trying my brother in law to see if he wants it. All of my friends bought ARs roughly 2-3 weeks ago so they are set. I might gift it to my 18 year son. Who knows. Might even keep it although I don't really "need" it. Felt I had to buy it at that price since it was so "low" these days. See the gougers "cost me" even when they did sell anything to me. Thanks for the help in advance.
