Up for sale is an absolutely awesome Colt LE6920 from 2013. This is a pre CZ acquisition gun. It is marked Colt M4 Carbine with an LE prefix serial number in the early 200,xxx range. All major components were made by Colt as referenced by C markings on upper receiver, C /MP marks on the barrel, bolt carrier, MPC marking on the bolt itself along with the white paint dot which was the proof mark that a bolt was suitable for use by the US government in the m4. As you know the colts being made today although may be solid guns, are largely subcontracted parts. These were made at a time where Colt did all the production in house and could ensure quality/durability of parts. 

Not particularly interested in trades at this time. It's an easy call to buy this over what colt is making these days. Must be willing to sign bill of sale. Thanks ! 8six5 4onefour 2fourzero8
