Description Upgrade your sniper rifle’s performance with the TTI VSR-10 90 Degree Piston, a premium internal component engineered for Tokyo Marui VSR-10 rifles and their compatible clones such as the JG BAR-10. Designed specifically for 90-degree zero-trigger mechanisms, this piston ensures flawless sear engagement and consistent energy transfer — vital for precision and durability under high-tension spring loads. Crafted from CNC-machined aluminium alloy and stainless steel, the TTI 90 Degree Piston delivers exceptional strength without unnecessary weight. Its twin O-ring system forms a perfect air seal, while Delrin guide rings maintain optimal alignment within the cylinder. As a result, the bolt cycle remains smooth, silent, and efficient, even when operating with powerful upgrade springs such as M150 or M170 configurations. Key Features 90-Degree Compatibility: Purpose-built for zero-trigger systems like the TTI VSS-Zero Trigger, ensuring stable engagement and eliminating slam-firing under heavy load. Maximum Compression: Twin O-ring design guarantees an airtight seal, enabling exceptional FPS consistency and reliable power delivery. Low Friction Cycling: Two Delrin guide rings reduce internal drag, leading to quieter operation and extended component longevity. Precision Construction: CNC aluminium body with stainless steel contact surfaces resists deformation and wear, maintaining accuracy shot after shot. Balanced Weight: At approximately 35g–45g, the lightweight profile enhances bolt speed and improves mechanical efficiency. Impact Dampening: Integrated rubber buffer pad softens piston impact, protecting the cylinder head and reducing acoustic output. The 90-degree engagement system distributes spring force vertically across the sear, enabling it to handle the stress of high-power configurations that would otherwise wear out standard 45-degree designs. Since this geometry reduces mechanical strain, the trigger mechanism retains its integrity even after prolonged use. By refining both air compression and mechanical alignment, the TTI 90 Degree Piston elevates your VSR-based rifle to true competition-grade performance. The precise sealing and smooth bolt travel result in a silent, stable, and powerful firing cycle — an essential upgrade for any sniper seeking consistent accuracy and stealth on the field.
