【Engineered by Veterans. Optimized for GBB Gas Efficiency.】

The MEC Hop Up Rubber is designed by airsoft industry veterans to eliminate the common performance bottlenecks in GBB (Gas Blowback) systems. Featuring a narrowed entrance diameter and enhanced coverage for the barrel’s open-cut area, this rubber provides a vastly improved air seal, ensuring maximum gas efficiency and FPS consistency.

Key Features & Technical Benefits:

• 💨 Superior Air Sealing: The precision-molded entrance ensures a tighter fit with the nozzle, while extra coverage at the barrel's top window prevents air leakage, resulting in more stable velocity.
• 🎯 Dual Equal Pressure Points: Internally, the contact patch provides two balanced pressure points. This stabilizes the BB’s backspin for a flatter trajectory and superior accuracy over long distances.
• 🛠️ Dual-Hardness Combo Pack: Tailor your performance to your build’s power:
  • Black (60 Degree): Optimized for 295-390 FPS. Ideal for standard setups and cool weather performance.
  • Purple (70 Degree): Optimized for 360-460 FPS. Built for heavy BBs and high-power Gas/CO2 systems.
• 🌍 Professional Compatibility: * Rifles: Tokyo Marui MWS AR-15 Series.
  • Pistols: Tokyo Marui Hi-Capa 4.3/5.1, 1911 Series.
  • VFC-made Platforms: Elite Force / Umarex Glock Series, SIG Sauer P320-M17/M18.

Specifications:

• Hardness: Black (60°) / Purple (70°)
• Material: High-grade Performance Rubber
• FPS Range: 295-460 FPS (depending on the color used)

💯 Small upgrade, massive difference. Maximize your GBB’s potential with MEC precision.
