The Prometheus Stainless Hard Cylinder Type B is a high-performance internal component engineered to maximize air volume efficiency for AEGs. Precision-machined from high-durability stainless steel, this cylinder features an external heatsink rib design that effectively dissipates heat generated by the piston head during rapid cycling. This cooling effect prevents the piston head O-ring from expanding excessively, reducing frictional resistance and maintaining a consistent air seal. While the required air volume is ultimately dependent on both your chosen BB weight and barrel length, this Type B cylinder provides the optimal volume outline for platforms with inner barrels between 401mm and 450mm.

Technical Specifications:

  • Recommended Barrel Length: 401mm – 450mm (Approximate outline for standard setups).
  • Material: High-grade stainless steel with a high-polish internal bore for reduced friction.
  • Cooling System: Integrated external heatsink ridges to dissipate heat and stabilize O-ring temperature.
  • Compatibility: Standard Tokyo Marui-spec Version 2, 3, and 6 gearboxes.
  • Primary Function: Provides optimized air compression and volume matching.
  • Performance Impact: Minimizes velocity variance and stabilizes trajectory by ensuring proper air-to-barrel ratio.
  • Northmark Vault Tech Tip: Air volume requirements shift based on BB weight; heavier BBs may require more volume despite barrel length outlines.
