Product Overview

The M-M11 S is a lightweight upper receiver for the full-size 9mm Mac-11 platform and works with semi-auto and NFA lower receivers.

The bolt is a semi-auto design that allows double-feed magazines to be used, provided your lower receiver's design uses them. It has been tested with EVO/AKV, MP5, PPS-43, GLOCK, STEN so far. While some OEM bolt assemblies may fit the upper receiver, we don't recommend their use.
