The Hopup Chamber ME unit is designed to accept the nozzle length from 21.00mm to 21.25mm, and fully compatible with most aftermarket soft and hard rubber bucking without losing FPS or dropping BBs.
The Hopup Chamber ME Housing is equipped with a new CNC Delrin Locking C-Clip design to hold the barrel tight without wobbling and twisting, and 3 compression springs on top, at the bottom, and in the center of housing to ensure the hopup unit is exactly centered, straight and airtight at all times when adapted to any V2 gearboxes with 11mm or 11.5mm inner bore.
More than that, the Hopup Chamber ME Pro unit is specially designed with BB Latching System to prevent dropping BBs after removing the magazine. The Latching System can be also manually opened to release BBs from inside hopup chamber by hand.
The Dual UV LED Boards and Module set is also included with this hopup chamber unit to glow BBs in the dark. Operating Voltage from 7VDC - 15VDC (2-4 cells LiPo, 6-13 cells NiCad).

***The Empty Magazine Detection Sensor and Electronic Switch Controller are optional add-ons to stop Motor/HPA firing when the magazine is empty. (Sold separately)
***Test results: FPS might be increased from 10FPS to 30FPS over stock setup. Please check your FPS!
