The USAS-12, made by Daewoo in South Korea, is one of the better box-fed shotguns available (I use that term loosely; there are not that many of them around). It was available as both a semiauto and a fully automatic model - although the semiautos were arbitrarily defined as Destructive Devices in 1994, and must now be registered as such. The fully automatic ones were already registered and were not impacted by that rule. While I have shot a semiauto USAS-12 before, I've not had the chance to try the full auto one...until today!

The USAS-12 is a really quite smooth and controllable shotgun in full auto. It has substantial recoil, of course (especially when running something like the full-power buckshot we used today), but it has a very long bolt travel and it's a heavy gun. The magazines are its Achilles' heel, as with most box-mag-fed shotguns. If you have one, stick to only high-quality magazines from Daewoo (the original manufacturer) if you want it to run well.

Thanks to DSA for giving me the chance to shoot this!
