ANGEL CUSTOM OMEGA PRO ZERO TRIGGER SYSTEM – VSR-10
90° PISTON ENGAGEMENT • ADJUSTABLE TRIGGER • STEEL SEARS • PISTON & CYLINDER HEAD INCLUDED
Replace the trigger and matched compression components in your compatible rifle with the Angel Custom OMEGA Pro Zero Trigger System.
This package combines an adjustable trigger assembly, a 90-degree aluminum piston and a stainless steel cylinder head. It is intended for selected VSR-style bolt-action airsoft rifles.
Confirm your exact rifle, cylinder and spring configuration before ordering. Some installations may require fitting or modification.
90-DEGREE PISTON ENGAGEMENT
The OMEGA uses a 90-degree piston sear paired with the included compatible piston.
This arrangement changes the engagement geometry compared with a conventional 45-degree system. Correct fit and adjustment remain essential for secure piston retention and normal operation.
The design does not eliminate all friction or guarantee a particular trigger-pull weight.
STEEL TRIGGER COMPONENTS
The supplied information identifies CNC-machined S136H steel sears, high-carbon steel trigger components and a stamped steel support plate.
These parts form the trigger and retention assembly. Their suitability depends on the complete build, including piston engagement, spring load and installation quality.
No verified maximum spring rating is established in the supplied information. Do not treat references to upgraded springs as approval for every high-load configuration.
ADJUSTABLE TRIGGER FEEL
The trigger offers adjustable sensitivity within the manufacturer’s permitted settings.
Follow Angel Custom’s adjustment instructions. Settings must preserve secure engagement and reliable safety operation rather than simply produce the lightest possible pull.
The supplied information identifies compatibility with the stock VSR-10 safety arrangement. Its operation must be checked on the completed installation.
INCLUDED PISTON & CYLINDER HEAD
The package includes a 90-degree aluminum MAX piston with a steel end cap and a SUS304 stainless steel cylinder head.
The piston also features Teflon spacers. Correct dimensions, alignment and sealing are necessary for the compression assembly to function as intended.
The kit does not guarantee increased FPS, improved accuracy or quieter operation. Results depend on the complete rifle.
VSR-STYLE PLATFORM FITMENT
The supplied compatibility information references selected Tokyo Marui VSR-10, VSR-11, G-Spec, KS and Echo1 M24/M28 applications.
Verify each exact model individually. Similar rifle names or appearances do not establish matching trigger mounts, cylinders or piston dimensions.
Some builds may require modification. Professional installation is recommended.

INSTALLATION & COMPATIBILITY NOTE
Have a qualified airsoft technician verify fitment, piston retention, trigger adjustment and safety operation.
Stop using the rifle if the piston fails to remain retained, releases unexpectedly or the safety does not function correctly.
After installation, test the rifle and chronograph it using your field’s required BB weight. Follow the venue’s muzzle-energy limits and engagement requirements.
