Bolt carrier group and charging handle are included. The upper comes fully assembled and properly headspaced, so you don't have to worry about that part.

Manufactured to MIL-SPEC and finished with a superior quality nitride finish that protects against corrosion and heat, our BCG will not let you down. To ensure that it will provide superior performance in your AR-15, each bolt carrier group undergoes high-pressure testing (HPT) and magnetic particle inspection (MPI).
