This Zion Arms Nebula Programmable trigger unit works for many airsoft weapons with Version 2 gearboxes. After you install it, you can program the gun to fire in bursts. From two-rounds bursts to five-round bursts, all you need to do is pick the right option.
The trigger is electronic, which is a reliable option for your AEG weapon. When you program the binary trigger, you can switch fire rates thanks to the internal electronics.
Whats more, you can program the trigger unit without linking any other devices to it. To change firing modes, all thats needed is to switch from semi to auto twice. Youll hear a beep before you can cycle through the modes by pulling the trigger.
