The Daewoo series of rifles are quite unique.  The carbine model, known as the K1A1 (amongst other things) in the United States, was a sort of blend between the AR-15 and AR-18, and the K2 clone (sold under various designations) was the perfect blend of the AR-15 and AK series with a little bit of FAL thrown in for good measure.  Unfortunately, Daewoo rifles didn't see much popularity, and this was both due to Daewoo being a new, unheard of name in the gun business at the time, and also due to the fact the model designations kept changing.  People couldn't keep up with them to place orders, and many people thought they must have issues if they had to keep changing their designation to boost sales.  People assumed they were trying to "clean the slate" of a bad track record in regards to the previous designation, but it was really just a matter of different importers deciding to call the rifles different things.  The Daewoo carbines (K1A1) and rifles (K2) were imported in the mid- to late-1980s until the federal ban on the importation of "non-sporting rifles."  The K1A1 couldn't really be altered to meet these new importation requirements, but the K2s could, and so a "post-ban" model was created, the DR200.  The DR200 featured a thumbhole stock, no bayonet lug, and a false flash hider so as to meet importation requirements.  As such, the Daewoo section has been split into two categories:  pre- and post-ban.
