AR-15 .223 rifle with a High Standard lower and unknown maker A2 upper. The rest of the parts are factory Colt parts. The busttstock is A1 with a cleaning kit under the trap, A2 round handguards, A1 forward assist, A1 flash suppressor and the barrel is a Colt 1x12 twist 20 inch barrel cut back to 16.1 inches. Comes with a green military silent sling. The upper and lower do not wiggle and the rifle functions flawlessly. I will sell for $1050, which includes shipping to your FFL.
