Mac-10 Stripped Upper Receiver

This stripped upper receiver is a great replacement for a worn out or damaged upper receiver, fits all Mac-10 9mm & .45 acp. All you need to complete the upper is a barrel pin and a barrel. It may require a bit of work to press in or tap in the pin after the barrel has been threaded into the receiver to insure proper fit. You may use thread lock over drilling a pin hole to keep the barrel in place. Gun smith may be necessary. *We also have uppers uncoated, please call or email for specifics**
