CNC Aluminum Advanced Speed Trigger (Style E) for EVO-3 is specially designed for fast response, smooth, and consistent trigger pull on the ASG 2018 CZ Scorpion EVO-3 Airsoft Rifles. The Advanced Speed Trigger is designed with a removable speed trigger plate to shorten trigger pull and prevent over-pull damage to the electronic switch on the controller board. The Advanced Speed Trigger is completely compatible with the stock trigger setting without the speed trigger plate. The main pivot pin of the trigger is made from Stainless Steel for maximum strength and durability. The trigger spring extension is carefully insulated to prevent a short circuit in the controller board. The body of the trigger is CNC machined out of a solid block of Aircraft Grade Aluminum. The Aluminum and Stainless Steel construction makes this trigger very strong and durable. Moreover, the trigger is carefully chamfered on the edges and securely fitted with three rubber pads to ensure comfort, enhanced traction, and secure grip. With unique shapes, stylish designs, and colors, we will have an option to fit your style needs.
