The new sixth generation of the popular AirsoftPro VSR ZERO Trigger builds upon the proven design of the previous generation and introduces a new option for individual trigger characteristic adjustment.
The main innovation is the Sear Engagement Adjustment feature. Users can choose between a larger safety margin or a shorter, more competition-oriented trigger pull according to their preferences. The adjustment can also be visually inspected through the inspection window located on the top side of the trigger housing.
All proven features of the previous generation have been retained, including the adjustable trigger position, optional safety lever installation, integrated hardened steel spring guide support, CNC manufacturing, and excellent durability when used with powerful springs.

SEAR ENGAGEMENT ADJUSTMENT
The sixth generation ZERO Trigger allows adjustment of the engagement depth between the piston sear and the trigger mechanism. By turning the adjustment screw, the overlap of the engagement surfaces can be changed, directly affecting the trigger characteristics.
Unlike most conventional trigger units, the engagement setting can be visually inspected without disassembling the mechanism by using the inspection window located on the top side of the housing.
Warning: Make adjustments only in small increments and thoroughly verify safe operation after every adjustment. Excessively small sear engagement may result in unintended piston release caused by impact, vibration, or forceful bolt closure.
ADJUSTABLE TRIGGER
The trigger position can be adjusted to achieve the ideal placement inside the trigger guard. The trigger slides within a machined slot and is secured by a small hex screw accessible even after the rifle has been assembled.
Smooth forward and rearward adjustment is possible within a range of up to 7 mm. This allows every user to set the trigger position according to hand size and personal preference.

WHY ZERO TRIGGER?
A durable and reliable trigger mechanism is one of the key requirements for a successful sniper rifle upgrade. Standard trigger units are usually sufficient for stock springs, but the risk of failure increases significantly when stronger springs are installed.
Rifles based on the Marui VSR system use a 45° piston sear design. While adequate for low-powered setups, the loads generated by stronger springs place significantly higher stress on the engagement surfaces.
When the bolt is cocked, the 45° engagement angle tends to lift the piston, causing it to tilt inside the cylinder. This may result in rough bolt operation, accelerated wear, or in extreme cases even unintended piston release.
The AirsoftPro ZERO Trigger utilizes a true 90° (0°) piston sear design, from which the name ZERO is derived. The piston remains properly aligned during cocking, does not tilt inside the cylinder, provides a larger engagement area, and is capable of handling powerful upgrade builds equipped with strong springs.
ZERO Trigger is supplied separately without piston, spring, or spring guide. Before purchasing, please ensure that your rifle uses a piston with a 90° (0°) sear catch.
