This is gun is marked Ingram, Military Armament Corporation. It is a full automatic, transferable, M10A1 9mm machine gun.mac 10 for sale . Great condition. The 9mm M10A1 is has the lowest rate of fire of all the MACs...making it very easy to control. These M10A1s were built like tanks compared to the lighter SWD M11 NINES. Since it fires 9mm it is also very cheap to shoot. One thing that makes this particular gun neat is it uses double feed magazines. Most 9mm MACs (including MAC 10s) use the single stack zytel magazines that are very hart to reload and wear out quickly! These are MUCH easier to load than the later single feed zytel magazines! You can easily load them with just your fingers, no mag loader required! Comes with original cobray folding stock. Comes with silencer, carrying case, and 4 magazines.
