Colt AR15 LE6940 COMPLETE upper receiver

Selling my upper receiver to my Colt LE6940. Upper is in very good condition, less than 1000 rounds fired through it. This upper feature's Colt's new monolithic upper receiver. In addition to an uninterrupted full-length front rail, this upper receiver allows for a free-floated barrel. This rifle also features a gas-block mounted front flip-up sight with bayonet lug and a MaTech backup rear sight. The barrel is Colt's standard 16.1" chrome lined M4 barrel with an A2 flash hider up front. The 1:7-inch twist of the barrel and 5.56x45 mm NATO chamber allow the use of 55-grain, 62-grain and 77-grain ammunition. The M4-style barrel measures 0.750 inches at the gas block, but decreases to 0.640 inches under the handguard, and incorporates the M4-style step. This auction is for the complete upper, bolt, bolt carrier, charging handle, etc. NO FFL required for delivery. Upper is being sold as is in an effort to provide a more simple transaction, any and all questions are welcome. If more pictures are wanted, please ask. Once again, the MaTech back up rear sight is included, the EOTech pictured is NOT included in the auction.
