Strange AR/Sten 9mm Hybrid with 2″ Barrel

    A reader noticed this strange looking short barreled rifle being auctioned off on GunBroker. The upper receive resembles the Sten submachine gun’s receiver and its lower looks to be a modified AR-15 lower with a AR-15 pistol grip and a A2-style stock.

    Despite being as long as a 5.56mm AR-15 with a 8″ barrel, this 9mm carbine has what looks to be a 2″ (maybe 3″ max.) barrel. A Glock 26 is going to have greater muzzle velocity. Still, I would love to have some trigger time with this gun. It looks like a lot of fun.

    The gun was built by a company named MK Gun Mods of Mt. Dora, Florida. The  auction’s “Buy Now” is $650 (not including the $200 tax stamp for the transfer).
