Action Army Specialized “Zero” Trigger Kit w/ 90 Degree Piston for Tokyo Marui / Well VSR-10 Airsoft Sniper Rifles

ACTION ARMY ZERO TRIGGER KIT WITH 90-DEGREE PISTON – VSR-10

ADJUSTABLE TRIGGER • MATCHED 90° PISTON • ALUMINUM & STEEL COMPONENTS • VSR-STYLE PLATFORM FITMENT

Replace the trigger and piston together with the Action Army Specialized Zero Trigger Kit with 90-Degree Piston. This set combines an adjustable trigger unit with a matching blue aluminum piston for compatible VSR-style spring airsoft rifles.

The supplied compatibility information names Tokyo Marui VSR and Well VSR platforms. Confirm fitment with your exact rifle, cylinder and spring setup before ordering.

MATCHED 90-DEGREE TRIGGER & PISTON

The kit pairs a Zero Trigger Unit with a 90-degree aluminum piston. The matched components provide the intended piston-to-sear engagement arrangement.

The 90-degree designation refers to the engagement geometry. It does not indicate a gearbox angle; VSR-style spring rifles use a manually cycled cylinder and piston system.

ADJUSTABLE TRIGGER FEEL

The trigger offers adjustment for pull weight and pre-travel, allowing its feel to be tailored within the manufacturer’s permitted settings.

Adjustment must preserve secure engagement and normal safety operation. Follow Action Army’s instructions rather than selecting settings solely for the shortest or lightest pull.

ALUMINUM & STEEL CONSTRUCTION

The supplied material information identifies aluminum, steel and rubber components. The included piston has an aluminum body and a blue finish.

Service life depends on installation, spring load, component compatibility and maintenance. No maximum spring rating is established in the supplied information.

VSR-STYLE COMPATIBILITY

The kit is intended for compatible Tokyo Marui VSR, Well VSR and other verified VSR-style spring rifles.

Although described as a drop-in upgrade, fit can vary between manufacturers and production versions. Check the receiver, cylinder, piston and spring requirements before installation.

Replacing the trigger and piston does not automatically improve accuracy, range or muzzle velocity. Those results depend on the complete rifle setup.

INCLUDED COMPONENTS

FREQUENTLY ASKED QUESTIONS

What comes in the kit?

The listed contents are one Zero Trigger Unit and one 90-degree blue piston.

Will it fit every VSR-style rifle?

No universal fit is guaranteed. Confirm compatibility with your exact rifle and its existing compression components.

Is the trigger adjustable?

Yes. Pull-weight and pre-travel adjustments are identified in the supplied information. Follow the manufacturer’s permitted adjustment procedure.

Does it increase FPS?

The kit alone does not guarantee a velocity increase. Output depends on the spring, air seal, barrel and complete compression system.

Can I use any upgrade spring?

No. Verify spring dimensions and the rated limits of the complete assembly. The supplied information does not establish a maximum spring rating.

Is installation always modification-free?

Not necessarily. The kit is described as drop-in for compatible platforms, but tolerances and existing parts can affect fit. A qualified airsoft technician can assess uncertain combinations.

INSTALLATION & COMPATIBILITY NOTE

Follow Action Army’s installation instructions. Have a qualified airsoft technician verify fitment and adjustment if you are unfamiliar with trigger and sear assemblies.

Before gameplay, verify secure piston engagement, normal safety operation and reliable cycling. Stop using the rifle if it releases unexpectedly or fails to retain the piston.

Chronograph the completed setup and follow your field’s muzzle-energy limits and engagement requirements.
