Prime Mech Airsoft, based in France, specializes in crafting high-end airsoft rifles known for their exceptional trigger response and quiet operation. Their custom Colt Commando XM177 build, for instance, uses the CYMA XM177e1 CM009E as its base. This particular rifle is upgraded with a Gate ASTER II Bluetooth unit, a 13:1 gearset with 13 teeth, and a 22 TPA motor, resulting in a power output of 1 joule with 0.28g BBs.
