One of the most important areas of your airsoft gun is how the trigger feels each time you pull it. The more precise and easier the pull, the more confidence you have with each follow up shot.
The SPEED M4/M16 Tunable Trigger is precision machined from billet aluminum, using hardened roller pin for a slop-free pull. Since each AEG has variations, the SPEED Tunable Trigger incorporates a setscrew for easy alignment to the trigger switch assembly unit. The spring guide also has a larger diameter for preventing the trigger return spring from moving around. The SPEED trigger has the same trigger geometry as the stock M4 so you will have the same feel but with more precision.
The SPEED Tunable Trigger will improve performance on a stock AEG switch unit, and will really excel with a MOSFET unit that uses a micro-switch. We recommend the SPEED M4 SE (Special Edition) Triggers for MOSFET upgrades.
