Chrome lined and phosphate bcg - Aero Precision AR15 5.56 Bolt Carrier Group (BCG)

AERO's BCG is a quality product for the money. The bolt headspaced correctly with Go and No-Go gauges as expected. The bolt is very clean in appearance. The Bolt and Carrier combo align perfectly when installing the cam pin. The chrome lining in the carrier is as clean as any other ive purchased or used in the military. If I were nit picking ide say the firing pin itself could be a little more cosmetically cleaner. As it arrived, the fit and function is perfect.
