I am getting rid of my extra parts.
I have an excellent condition M16/AR-15 bolt complete but no carrier. It is marked "MP" and looks very close to new. I am not sure who made it. $45.00 shipped to you. I will take a MO or paypal with no upcharge but email me first so I can give you my paypal address. It is not my ar15.com email address.
I have pics I will email, I don't know how to post images here. The are overexposed to show detail the best I can with my little camera.
email or IM
