ThisIan goes over the APS Scorpion D-Mod Gas Blowback Pistol in this Bunny Workshop review... "A.P.S. Scorpion D-MOD GBB Pistol features an ergonomically polymer frame, with lightly textured grip panels, providing a comfortable and effective non-slip grip. At the business end of the frame is a 20mm accessory rail, perfect for mounting weapon lights or lasers. The slide is constructed from a heavyweight metal alloy giving the Pistol a hefty, realistic weight.
This Pistol is CO2 Power and D-MOD gas system. D-MOD pistols are compatible with both CO2 and Green Gas (Each gun comes with one magazine of each)."
