Carter Machine Grey Blue Autococker body, missing feedneck, includes bolt and back block. Definitely a project. I bought this a long time ago and was going to send it to Earon and have him add a stock feed but never got around to it. It includes the Carter Machine bolt, which is also cut for the flip wheel back block. Back of bolt is aluminum and front is delrin. Serial (cut in half) looks like 13971 but I have no way to vertify. EMpty, has extra hole in top to secure feedneck. Includes ONLY Body, bolt and back block.
