Here's what it looks like with the buttstock folded.
That firearm looks like 3 main rifles had a love child.
How the third got in there, I don’t want to know...
Ha ha! Yah, it's a little funky looking I'll grant you that.
The upper receiver looks weird because they cut off the M-16/AR-15 carrying handle, but kept the M-16/AR-15 rear sight and put on a ringed front sight. Since it uses an AK-47 gas system with piston and telescopic recoil spring, they were able to incorporate the FN-FAL folding stock. They cut down the buttstock to give access to the charging handle and mag release when it's folded. So, the weird look is a form follows function thing.
Once you get past all that and shoot it, you realize what a great .22 rifle it really is. IMO, head and shoulders above an AR-15.
As I understand it, Daewoo had the license to manufacture the M-16 for the ROK Army. When the license ran out, they took what they consider the best of three rifle systems (M-16, AK-47 & FN-FAL) and put them together to make the K2.
The K1 was based upon the Armalite AR-18 gas system, so it's a horse of an entirely different color and a piece of junk when compared to the K2.
Like I say, it's robust, reliable and accurate. It's like the Energizer Bunny. It keeps going, and going, and going...
