Anderson Mil-Spec Complete Upper with 16" Heavy Barrel (Heavy Barrels take longer to heat up producing better shot groups for longer periods of time). Upper will mate to any mil-spec AR-15 lower. Also, Jerry Miculek 30 cal Compensator included. Optic is Vortex Strike Eagle 1-6 variable power and is included in the price. $500 will take everything. Only 200 rounds through the upper.
