KAC SR15 Legacy (pre-owned)

Pre-owned Knights Armament Co. SR15 Legacy model. Complete factory gun. Pre 2010 model from when the QD cup lower, KAC adjustable 2 stage trigger and URX2 quad rail with built in flip up front sight was the norm. Please note, this gun has marks on the gas block which indicates to me it has been disassembled, but all of the parts are factory. The only change I can see would be the flip up rear sight is the Knights Micro version instead of the "big wheel" version that it would have had out of the box. Includes factory mag with white KAC anti tilt follower and factory manual. Original plastic case is not included. The gun is used but in good shape without any major scratches or blems with the exception of the marks on the rear/sides of gas block.
