Full Size ALL STEEL Parked finish Replica M3A1 Greasegun, as issued in Viet-Nam.  Removable mag, moving bolt and trigger.  One mag included with a few rounds to top off the mag.  Mags are original, and can be either Blued or Parkerized.  They are surplus, various years, and we never know til we take them out of the wrapper.  This is the Suppressed version, and we got the correct profile here, the M3 Suppressed gun is different!
