I'm selling a like new Colt bolt and carrier assembly from my MT6400C. The bolt is marked "MPC" and the carrier is marked "C". This assembly has a very low round count, under 50.
Lower Price: $110 shipped. PayPal is 3% extra. Will trade for new USGI 30-rd. magazines (must be recent manufacture) or a Colt M16 bolt carrier (new issue). Email or IM me.
