Has anyone ever seen or know anything about a Colt MT6400C? It is allegitly a post-ban Colt M4 w/ factory compensator. I have never seen one. The only reason I know about it is because www.Gunfinder.net had some for sale. If you check their search engine use "Colt Mfg" for the manufacturer, and "long gun" as the descriptor. The MT6400C will be at the top of the list, out of stock mind you, for $1,034.36. If anyone has any info please enlighten me.
