Military Manufacturing Corporation M16X With Suppressor
It's the shortest barreled .5'56x45mm-NATO carbine produced in the world today. Well, maybe the short barrel (4,1 INCHES ONLY!) makes it a bit inaccurate from the distances (although some say the M16-X is good at 50 Yards, 25 at MML, with a muzzle velocity of 1620 Feet per Second with M193 ball), and probably a NIGHTMARE to fire in full-auto (oh, poor my eyes and and ears!). In semi-automatic only, however, it is told to be a gread Personal Defence Weapon for those who need it. Due to its enormous muzzle flash and deafening noise, a sound suppressor becomes practically unavoidable if using it in confined spaces.
