Description Upgrade your Tokyo Marui VSR-10 or compatible clone with the TTI Airsoft VSR-10 45 Degree Piston, engineered for precision, consistency and superior air compression performance. Designed by TTI Airsoft, this CNC-machined piston refines every aspect of the bolt-action cycle to deliver smoother operation, improved air seal and enhanced shot stability — vital for long-range accuracy and reliability. Constructed from lightweight aluminium alloy and stainless steel, this piston ensures strength without excess mass, allowing a faster, cleaner bolt pull. Its advanced Twin O-Ring system delivers exceptional air retention, leading to stable FPS and consistent muzzle velocity — a crucial factor in maximising the energy transfer from spring to BB. Because the piston utilises Delrin guide rings, friction is significantly reduced, enabling quieter operation and a notably lighter bolt response. This piston is the ideal choice for users retaining the 45-degree trigger sear system, especially those running high-tension springs with reinforced steel sears. It maintains compatibility with popular rifles such as the Tokyo Marui VSR-10, JG BAR-10, and Well MB-03/MB-07, ensuring straightforward installation and dependable upgrade potential. Key Features VSR-10 Compatibility: Direct replacement for 45-degree systems on Tokyo Marui VSR-10, JG BAR-10 and Well MB-03/07 platforms. Twin O-Ring Compression: Dual sealing system guarantees airtight performance and consistent FPS output. Low-Friction Delrin Guides: Reduces internal resistance and enhances bolt smoothness for quicker cycling. Precision Aluminium Construction: CNC-machined body with stainless steel reinforcement ensures strength and longevity. Integrated Rubber Buffer: Absorbs impact on the cylinder head to minimise wear and operational noise. Optimised Weight Balance: Lightweight profile supports improved bolt efficiency and shot-to-shot consistency. The TTI Airsoft 45 Degree Piston is an essential upgrade for those refining their VSR-10 setup while keeping the original sear configuration. Since its twin-seal and low-friction engineering maintain both durability and stealth, it provides an optimal solution for high-performance bolt-action rifles used in demanding skirmish environments.
