MAC 10, the gun that made the '80s roar! I have one and its a blast to shoot if you have a few thousand rounds you want to get rid of fast! but, as the old '80s saying goes; "they are only good for shooting Columbians in elevators". the sight are purely ornamental. with a suppressor or barrel extension they are controllable, but you shoot it like you would squirt with a garden hose. 😁The absolutely worse thing I ever fired was an open bolt MAC-10 pistol. Yep, the old pre ATF ruling against them one. At least half the weight was in that bolt that of course slammed forwards to fire. Without a stock and a suppressor or barrel extension on it was useless.
