I can hit a 10 inch circle at 100 yards with both of my UZI’s set on semi. I haven’t tried it on full auto but I’ll be at the range this week and I’ll try it.
If you know what you’re doing, the UZI can be quite accurate for what it is. With a closed bolt design, it’s very accurate.
On the gun in the OP’s article... that’s ugly. It appears that they took a micro UZI receiver and tapco tacticooled it.
Try one at night, out of the loader's hatch of an M48 tank, against a guy four feet away on the back deck of the tank behind the turret, hoping to drop a 15-pound satchel charge down the commander's open hatch.
Too close to swing the antiaircraft/antisapper machinegun around, and you've got an Uzi with a full 25-round magazine in your hand, the shorter mag being preferred inside the tank as less likely to snag while getting out.
You have less than three seconds for your eyes to adapt to the dark, identify and acquire your hostile target, and engage, after which you'll be night-blind from the muzzle flash. Full auto magazine dumps are acceptable, so long as you clear your target and discourage any of his friends who might be thinking about trying the same thing. Head shots preferred.
No tank? Try it with a pickup truck, firing from the back end over the cab at a silhouette target fixed to a 2x4 posted verticle to the front bumper.
Hint: it's not as easy as it sounds.
