This is a machined and hardened steel part of the MG34 charging handle that contacts the bolt carrier to charge the gun. It is designed for our replacement MG34 charging handles. It may also be used to replace broken cocking pieces. Rather than being held by 2 rivets, it is threaded for button head screws (6-32, 2 included). It can still be riveted as per the original design or the other part of the handle can be threaded to accommodate this part.
