TNA Bolt Carrier Group (5.56 Bolt)

  • 15997


M16 extreme duty-ready complete bolt and carrier assembly with firing pin. Because this is an M16-ready bolt carrier group, the carrier is heavier than a typical semi auto AR15 carrier due to additional material in the back end which results in better firing rhythm.

Don't let the price of this product fool you, this is a quality part that does not disappoint.
