With so much “tacti-cool” stuff hitting the black rifle market, there’s nothing wrong with taking a step back and building a truly classic rifle. This Classic AR-15 Upper Assembly features an old school A2-style upper, complete with an A2 front sight post, A2-style “bird cage” flash hider, and traditional forged M4 flattop upper.
Included with the upper assembly is a chrome-lined M16 bolt carrier group with staked gas key and M4 feed ramps. The 4150 CMV barrel promises MOA accuracy with bomb-proof reliability.
