Daewoo DR-200 Rifle
It's really too bad that the Daewoo assault rifles were banned from import (under Bush I, by the way). They are basically the S. Korean version of the AR-15, some parts are even interchangeable. But, the Daewoo uses long-stroke gas piston operation--almost identical to the AK-47.
Best of both worlds. Very accurate. Very reliable. If you ever stumble across one, give some serious consideration to buying it. Any one have site, dealer, to purchase one?????
