ASG have their own MK23 spring pressure pistol that Geonox Airsoft features in this pistol... "In this video I show you the DL60 spring pressure Airsoft. It is an Airsoft replica in the MK23 look. The first thing that came to mind was SSC23. The nice thing about the DL60 is that we have a thread for a tracer or silencer. She even manages to hop very heavy 0.30g BBs. And these fly straight. Currently my favorite spring pressure.
