M150 SPRING
This complete VSR upgrade kit delivers maximum reliability even with powerful springs up to M170. At its core is the ZERO Trigger Gen.6 with a 90° piston sear, ensuring consistent piston engagement without canting while significantly reducing wear. The new Sear Engagement Adjustment feature allows you to fine-tune the trigger characteristics from a safe trigger pull to a short competition-style break. An inspection window lets you check the adjustment without disassembly. The lightweight ZERO piston with POM guide rings provides smooth cylinder operation, while the stainless steel bearing spring guide eliminates spring twisting during compression. The entire system is engineered as a fully compatible upgrade package for long-term durability and maximum performance, eliminating the need to test individual parts for compatibility. Everything you need comes in one box.
All components are designed to work together perfectly without compatibility testing.
90° piston sear for superior reliability and elimination of piston canting.
Adjust the trigger feel from SAFE to SPORT settings.
Aluminum body with POM guide rings for smoother operation and reduced wear.
Reduces friction and prevents spring twisting during compression.
Built to handle demanding upgrade builds.
In most cases, no. Some models (such as newer JG BAR-10 rifles) may require minor modification due to different screw sizes.
The ZERO system uses a 90° piston sear that eliminates piston lift and canting inside the cylinder, resulting in smoother operation and a much longer service life.
Yes, although its full potential is realized with stronger springs. With lighter springs, the main benefits are improved trigger feel and greater durability.
No. The adjustment is easily accessible, and the inspection window allows you to verify the setting without disassembly. However, adjustments should always be made gradually and followed by proper safety testing.
