Up for sale is a good condition COMPLETE 14.5" Faxon gunner barrel in 1/8 twist (with extended flash hider for 16" barrel total length). The Faxon Gunner series has a pencil (0.625") diameter from the gas block foward to reduce weight, and government profile under the handguard to increase barrel rigidity. The flash hider is designed with a slim outside diameter so the gas block & barrel nut can be slid over if the end user ever wants to change out handguard types. This upper has ~500 rounds on it and has always been cleaned after usage. It is in very good mechanical shape! 


The upper is built on a Rock River Arms flat top upper (w/ M4 feed ramps), and an Aero Ehanced Gen 2 Rifle Length Handguard. At ~11.8 oz for the handguard and ~19.04 oz for the barrel, this is a very light weight and accurate carbine!
