Maple leaf m165 upgrade spring for marui vsr sniper series

Take your VSR build to the next level with the Maple Leaf M165 Upgrade Spring, designed for the Tokyo Marui VSR sniper series and compatible VSR-style platforms. This is a high-power spring intended for performance-focused sniper builds where maximum output and long-range potential are the goal - when paired with the right supporting upgrades and careful tuning.

An M165-rated spring is aimed at very high power builds, so it's best suited to experienced players/techs who understand site limits and the importance of balancing the full system (air seal, cylinder volume, piston, spring guide, hop setup, and BB weight). If you're rebuilding a rifle for a specific power target, the M165 spring provides a strong foundation for a serious VSR upgrade.
