Taiwan Gun shows what improvements the Well Pro MB08AE Upgraded Version has in a range test. The replica boasts a stainless steel cylinder and piston, an aluminum 90° piston with a seal cup-type head, and a steel trigger assembly. These components, along with a standard APS2 9mm spring and a 90° trigger box with a new trigger type, allow the replica to accommodate M220 springs for up to 680 FPS. For ease of maintenance, the cylinder set can be disassembled without dismantling the entire replica. The MB08AE also features a 500mm barrel with a diameter of 6.03mm and an upgraded hop-up chamber with an innovative hop-up rubber for smooth rotation of BBs up to 0.50g. Practical features include a loading indicator on the bolt and an empty magazine indicator on the barrel.
