A descendant of Ingram's M10, the M11/Nine is made with a slightly longer receiver than the M11 to accommodate a caliber upgrade from 380 ACP to 9mm Parabellum and allow for a longer range of bolt travel to dampen felt recoil. Fixed blade and peep sights, with a side-cocking upper receiver installed, threaded muzzle, canvas sling foregrip, "SEMI/SMG" selector switch on the left side of the frame, safety switch next to the trigger guard and standard markings on the right side of the frame. Fitted with a textured pistol grip extension and a two-position telescoping buttstock. A Fleming M11-22 22 LR upper receiver assembly is also included, along with three Ram-Line extended 10-22 magazines, eight 9mm magazines (3 modified steel Sten magazines, the remainder plastic), faux silencer, loading tool, sling, manual, and a generic plastic case.

Very fine as upgraded to current configuration, with 95% of the matte gray phosphate finish, showing mild wear and handling marks. The extra upper receiver is in comparable condition, with mild spotting on the rear sight. Mechanically excellent. NOTE: This weapon is a National Firearms Act (NFA), fully transferable Class 3, which is registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives, (BATFE) under the provisions of 18 U.S.C.
