A) RPB/Military Armament Corp. M11 SMG, Class III/NFA Fully Transferable Machine Gun

Manufacturer: RPB Industries

Barrel: 5 inch round
Finish: matte grey

Stock: metal
Item Views: 3072
Item Interest: Very Active
Serial Number:
Catalog Page: 346
Class: Class III
Description:

Developed by the Military Armaments Corporation and manufactured by RPB, both of Georgia, the M11 is a compact machine pistol chambering the 380 ACP cartridge (aka 9mm Kurz), and along with the rest of the Ingram family of automatic weapons was one of the signature firearms of the Cold War era. Features fixed blade front and peep rear sights, with the "SEMI"/"FULL" selector on the left side, the safety on the underside. This example comes with an "operational" briefcase, which has a cutout in the interior to secure both the gun and included suppressor inside, with a hole cut in the side of the briefcase aligned with the muzzle, a metal shell deflector installed inside the briefcase, and a transfer lever protruding from the bottom that interacts with the trigger. This makes for an extremely covert package, hiding the gun and included silencer described in item "B" in plain sight while allowing their rapid fire through an otherwise unassuming briefcase. Also induced are a nylon front grip strap, Ingram user's manual, keys, spent casing retaining bag, a two-position telescoping wire buttstock, and three extra magazines.
