TNA Premium Bolt Carrier Group (5.56 Bolt) MPI Shot Peened Chrome Lined Carrier

TNA Premium Bolt Carrier Group (5.56 Bolt) MPI Shot Peened Chrome Lined Carrier

  • 18997


This is our premium white-label BCG. American-made M16 extreme duty-ready complete bolt and carrier assembly with firing pin. The carrier is heavier than a typical semi auto AR-15 carrier due to additional material in the back end which some folks believe results in a better firing rhythm. 

The gas key is lightly  staked. Don't let the price of this product fool you, this is a high quality part that does not disappoint.
