The Retro Arms CNC Stainless Steel Cylinder Type C is a highly robust internal component engineered to increase the durability and compression efficiency of electric airsoft guns. Precisely machined from high-grade stainless steel, it features a high-polish internal finish to minimize frictional resistance against the piston head O-ring during high-speed cycling. This cylinder is engineered with a slightly larger internal diameter than most standard cylinders on the market, making it more of a "bore up" option that provides increased air volume for superior compression. While the required air volume is ultimately dependent on both your chosen BB weight and barrel length, this Type C cylinder provides the optimal volume outline for standard mid-length platforms between 290mm and 369mm.

Technical Specifications:

  • Recommended Barrel Length: 290mm – 369mm (Simplified guideline based on standard setups).
  • Material: CNC-machined Stainless Steel for maximum structural integrity and corrosion resistance.
  • Internal Profile: Enlarged internal diameter for increased air volume (Bore Up style).
  • Finish: High-polish internal bore for reduced friction and a consistent air seal.
  • Type: Type C (Ported).
  • Compatibility: Standard Tokyo Marui-spec gearboxes; specifically optimized for Retro Arms gearbox shells.
  • Northmark Vault Tech Tip: Because this features a larger internal diameter, Northmark Vault recommends ensuring your piston head O-ring provides a proper seal for this bore up profile. Air volume requirements also shift based on BB weight.
