L'Antre Du Dingo installs and checks the MAXX Hop-up For ASG Scorpion EVO A1. The Maxx CNC Aluminium Hopup Chamber EVO unit is an upgrade for ASG CZ Scorpion EVO-3 Airsoft Rifles, featuring a precisely machined design for accuracy and consistency. It has a rotary dial for fine-tuning hop-up adjustments and includes a bucking nub for both R-Hop and standard setups. The unit is compatible with most aftermarket buckings and nozzles, and its self-centering inlet and Delrin locking C-Clip ensure a wobble-free fit for both the hop-up unit and inner barrel.
