CNC Aluminum Hopup Chamber EVO unit is precisely machined to perform accurately and consistently on the ASG 2018 CZ Scorpion EVO-3 Airsoft Rifles. The Hopup Chamber EVO unit is built with a Precision Aluminum Rotary Dial Knob for fine hopup adjustments and equipped with 4mm Flat Soft Bucking Nub (6mm Bucking Nub is optional) to perform best with R-Hop and Standard-Hop to keep the BB shooting accurately and consistently on every single shot. The Hopup Chamber EVO unit is designed to accept the 18.5mm nozzle length, and fully compatible with most aftermarket soft and hard rubber buckings without losing FPS or dropping BB during use. The Hopup Chamber EVO unit is wisely built with a self-centring inlet to ensure the hopup unit is inserted exactly in the center of the 11.5mm inner bore ASG EVO-3 gear box outlet without wobbling. Also included an advanced CNC Delrin Locking C-Clip to hold the inner barrel tight in place without wobbling and twisting. ***The Dual UV LED Tracer Module is an add-on option to glow BB in the dark. Operating Voltage from 7VDC - 15VDC (2-4 cells LiPo, 6-13 cells NiCad). (Sold separately) ***Test results: FPS might be increased from 10FPS to 30FPS over the stock setup. Please check your FPS!
