All "DR-200" rifles are post-ban. A folding stock would be illegal on that gun.
Pre-ban Daewoos of that model will be marked "K2" "Max-II" or "AR-100" depending on the importer. They came with a side folder as standard. The side folder is a solid plastic stock, not a tube Galil-type.
Just check the markings. If it's marked "DR-200" then it's a post-ban and can't have a folder. Unlike some guns that can be confusing as to their pre/post status, there was a solid break in time between when the pre-bans were sold and the post-bans were. It's either a pre-ban or a post-ban, no in between.
As a rifle they are a great one. Basically an AR with AK gas system. High-quality and used as the standard Infantry rifle of the ROK. It's not some cheap rifle that's never been tested. It's a great rifle pure and simple with many features that put an AR to shame.
It takes M16 mags, but spare parts are next to impossible to get. Lack of spares turns off many. I have had a K2 forever and love the gun, but if it ever broke I'd have to have the part made.
