LayLax Airsoft PSS10 Super Light Weight Piston VSR-10 45 Degree

LayLax PSS10 Super Light Weight Piston for VSR-10 / G-SPEC – 45 Degree

The LayLax PSS10 Super Light Weight Piston from Bullseye Country Sport is a high-performance internal upgrade designed for Tokyo Marui VSR-10 and G-SPEC airsoft sniper rifle platforms using 45 degree trigger sear systems. Built as part of the highly respected PSS10 sniper upgrade range, this piston is engineered to improve bolt operation, efficiency and overall consistency in tuned VSR builds.

Designed with lightweight performance in mind, the reduced piston mass helps minimise unnecessary stress on internal components while contributing to smoother bolt cycling and improved operational efficiency. Lightweight pistons are especially popular in precision sniper builds where consistent compression and refined bolt feel are priorities.

This piston is specifically designed for use with 45 degree trigger systems, making compatibility important when installing into upgraded rifles. It is intended for standard-style VSR trigger units and compatible 45 degree setups, but is not suitable for 90 degree trigger configurations.

With an overall length of approximately 128 mm, a maximum outer diameter of 22 mm, and a maximum inner diameter of 13 mm, the piston is designed to provide a precise fit within compatible VSR cylinder assemblies while maintaining lightweight performance characteristics.

LayLax designed the piston to provide dependable air seal performance and consistent operation over extended use while maintaining the high machining quality the PSS10 range is known for. As with many sniper upgrades, proper installation and compatibility checking are important for achieving the best possible results.

Ideal for Tokyo Marui VSR-10 builds, G-SPEC upgrades and lightweight sniper rifle setups, this piston is an excellent choice for players looking to improve the feel and efficiency of their rifle without adding unnecessary stress to the system.

At Bullseye Country Sport, we reckon VSR builds are one of those dangerous projects where “just one upgrade” somehow turns into rebuilding the entire rifle.
