Upgrade your Airsoft sniper rifle with precision and power using the Laylax PSS10 Upgrade Spring 150SP (Aqua)—an elite internal component built for serious marksmen running Tokyo Marui VSR-10 series and compatible bolt-action sniper platforms. Engineered for consistency, durability, and enhanced shooting performance, this spring is a trusted choice among players seeking reliable long-range precision on the field.

Constructed from high-quality spring steel, the 150SP is designed to maintain uniform compression and tension through repeated use, delivering consistent power output with every shot. It helps stabilize your rifle’s firing mechanism, which can lead to improved shot-to-shot accuracy, tighter groupings, and better engagement at extended distances.

Rated for approximately 500 FPS when using a 0.20g BB, this spring offers a significant power increase—ideal for field-legal sniper builds where high velocity is required to punch through wind resistance or reach distant targets. Please note that actual FPS may vary depending on your rifle’s internal setup, such as the inner barrel length, cylinder volume, air seal, and hop-up configuration.

One of the standout design features of the Laylax PSS10 spring series is its color-coded system. Each spring is anodized in a unique color—in this case, Aqua Blue—for quick visual identification of spring strength, even if you’ve misplaced the packaging. This helps keep your tech bench organized and simplifies spring swaps during builds or tune-ups.

Laylax’s naming convention also follows a meters-per-second (M/S) rating system for added convenience. The 150SP label corresponds to a rough velocity of 150 m/s, or around 492 FPS, allowing you to estimate performance expectations and stay within field limits or personal preferences. This transparency ensures you’re not just buying power—you’re buying predictable performance.

Whether you’re upgrading your Tokyo Marui VSR-10, JG BAR-10, or another compatible rifle, the Laylax 150SP spring is an excellent internal enhancement. With stable energy output and improved firing consistency, it’s a must-have for airsoft snipers who rely on precision shooting in outdoor skirmishes, milsim events, or long-range scenarios.
