Have recently purchased the DY9 "Island" upper. This is a very nice addition to an already solid pistol. The install is seamless and the results are noticeable right out of the gate. I find it very "Cool" that Derya has chosen to manufacture a quality yet affordable pistol and then also support it with quality affordable accessories. I've never had so much fun playing with guns!
