Finally finished my Daewoo K2. I went the opposite route of @mightyjebus and @HuttArmouries and HPA'd mine - only because I dont have the money nor care to build up a good AEG gearbox right now and I do have a spare Polarstar Fusion Engine lying around. I added a real steel Stormwerkz K2 rail because I hate iron sights, a Vortex Sparc2 on a Rogers Riser, a Rogers Rail Light since there was still some room on the rail, and a Phantom flash hider, simply because thats the closest one I could find to what the K2s in service have on them. I was forced to use the less than ideal but still OK hop unit from the K2 as it is too tight for my spare Maxx, ProWin, or really any standard AR hop unit, but its got my spare barrel, bucking, and flat hop from my SR-25 so it should have some good range.
