AirsoftPro Upgrade Trigger Box VSR ZERO Gen. 5

AirsoftPro VSR ZERO Gen. 5 Upgrade Trigger Unit

The 5th generation of the popular ZERO trigger unit builds on previous versions with a thoroughly redesigned construction. The new housing with beveled edges follows the receiver profile more closely, while the integrated steel reinforcement increases overall rigidity. The package once again includes a functional safety, which can be installed or omitted according to user preference. Each trigger unit also features its own unique serial number. The mechanism uses the proven ZERO piston sear, which engages the piston at a 90° angle. Unlike conventional 45° trigger units, this design prevents piston tilting inside the cylinder, improves reliability, and significantly extends service life when using powerful upgrade springs. The two-piece trigger also allows the trigger position to be adjusted by approximately 7 mm.
