VSR ZERO Trigger Gen. 6 upgrade trigger mechanism.
Supplied without piston, spring, or spring guide.
Before purchasing, please ensure that your rifle uses a piston
with a 90° (0°) sear catch.
A durable CNC trigger box for VSR10 airsoft sniper rifles featureing
adjustable sear engagement, a smooth trigger pull, and maximum
reliability even when using powerful springs up to M170.
An absolutely essential upgrade component when increasing the power
of your sniper rifle.
Gen 6 version builds upon the proven design of the previous generation
and introduces a new option for individual trigger characteristic adjustment.
Main innovation is the Sear Engagement Adjustment feature. 
User may 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:
this Gen 6  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.
SAFE:
larger sear overlap providing the highest safety margin.
SPORT:
balanced setting offering a compromise between safety and a
shorter trigger pull.
RISK:
minimal sear overlap.
Provides the shortest trigger pull but significantly reduces the
safety margin of the mechanism.
PLEASE NOTE:
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.
SPECIFICATIONS & FEATURES:
each unit is marked with a unique serial number.
Easy installation within minutes.
Tested with springs up to M170.
The trigger housing is CNC-machined from lightweight yet durable
6061-T6 aluminum alloy.

The piston sear, lever, and spring guide support are manufactured from
 steel and heat treated to a hardness of HRC 28–32.
The trigger incorporates a ball bearing for a smoother trigger pull.
Horizontally adjustable trigger with an adjustment range of up to 7 mm.
New adjustable sear engagement for individual trigger tuning.
Inspection window allowing visual verification of the engagement setting.
Internal pins are manufactured from stainless steel.
A pair of double-torsion springs reliably returns
the sear to its default position.
The trigger mechanism consists of 29 individual components.
A safety lever is included in the package.
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 Tokyo 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.
This 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.
Not compatible with MA4401, MA4402, Marui AWS series
and similar systems.
Also not suitable for M24 rifles.
Can be used with both original cylinders and reinforced AirsoftPro
upgrade components.
