TTI 45 Degree Piston for VSR10 - TTI-S0004

Key Features:

• VSR-10 Compatibility: Direct replacement piston for Tokyo Marui VSR-10 and compatible clones (e.g., JG BAR-10, Well MB-03/07) utilizing the 45-degree trigger sear angle.
• High Compression Design: Features a Twin O-Ring design, including a substantially larger main O-ring, to ensure maximum air seal and air volume transfer.
• Low Friction Runner: Equipped with two Delrin guide rings that minimize friction against the cylinder wall, resulting in a smoother, faster, and quieter bolt pull.
• Durable Construction: Made from a combination of lightweight CNC Aluminium Alloy and Stainless Steel for high durability without adding excessive weight.
• Shock Absorption: Includes a rubber buffer pad on the piston head to reduce the impact shock against the cylinder head, lessening noise and system wear.
• Optimized Weight: Precision-machined to be lightweight ($\sim 45 \text{ g}$), aiding in bolt response and consistency.
• Required Upgrade: Designed for rifles using high-tension springs that retain the stock 45-degree trigger box (ideally paired with a steel 45-degree sear).

Air Seal Mastery with Dual O-Rings

Achieving perfect air seal is the foundation of sniper rifle consistency and power. The TTI piston features an advanced Twin O-Ring design where a large primary O-ring manages the main compression seal, and a secondary O-ring acts as a critical backup, minimizing air leakage even under the pressure of high-power springs. This superior air seal directly translates to stable FPS and maximum conversion of spring energy into muzzle velocity.

Low Friction, High Durability

The piston body is constructed from lightweight CNC Aluminium Alloy combined with stainless steel components for a balance of durability and speed. Crucially, the piston runs on two low-friction Delrin guide rings. These rings guide the piston smoothly along the cylinder wall, drastically reducing internal friction and preventing "piston slap," which translates into a lighter, faster, and quieter bolt pull—key attributes for any successful airsoft sniper. The integrated rubber buffer pad also minimizes impact noise when the piston hits the cylinder head.

The Best 45-Degree Upgrade

While many high-end VSR-10 upgrade parts require switching to the 90-degree trigger system, the TTI 45-degree piston is purpose-built for those upgrading their existing 45-degree trigger box (we strongly recommend pairing this with a reinforced steel 45-degree sear for safety and longevity when using stronger springs).
