FPS Zero Shock Full Metal Rack 14 Teeth Piston PM03 - Maximum Durability and Performance

FPS introduces the Zero Shock Full Metal Rack 14 Teeth Piston (PM03), a top-tier component designed to enhance airsoft replicas' performance. Featuring a technopolymer body and full-metal teeth, the patented Zero-Shock system ensures unmatched durability and reliability.

Technical Specifications:

Zero-Shock System:

• Reduces stress transmitted from the rack to the piston body.
• Significantly increases durability and reliability compared to standard pistons.

Body Material:

• Technopolymer with a small percentage of elastomer for superior mechanical performance and low friction.

Rack:

• Technology: Manufactured using MIM (Metal Injection Molding) for precision and robustness.
• Material: SAE 4650 steel with surface hardening treatment (HRC38-42°).
• Teeth Configuration:
  • Second tooth removed.
  • Third tooth lowered by 0.3 mm for optimal Angle of Engagement (AOE).

Functional Design:

• Guides: Minimize friction and retain lubricant for extended use.
• Rack Seat: Offset to optimize gear meshing with the sector gear.
• Longitudinal Reinforcements: Enhance robustness and prevent rack contact with cylinder walls.
• Internal Ribs:
  • Reduce contact between the spring and piston body.
  • Minimize friction during contraction and expansion.

Key Benefits:

• High-Speed Performance: Optimized for rapid and precise firing cycles.
• Superior Reliability: Thanks to the Zero-Shock system and robust materials.
• Universal Compatibility: Compatible with most Marui gearbox replicas.
• Italian Excellence: 100% Made in Italy, ensuring quality and innovation.
