Airtech Studios TDC Trolly & M-Nub (R Hop) - Retro Arms Hop-Up Chamber

  • The TDC (Top Down Centre) Trolley is designed for the Retroarms Hop-up chambers to incorporate the traditional usage of M-nubs which works perfectly with the R-Hop patches to achieve an improvement in accuracy and consistency from shot to shot.

  • The M-nub ensures an evenly distributed force applied onto the bucking down to the RHOP patch. This in turn ensures the patch can maximize its appliance on the BB for the most stable and uniform spin for the much desired R-hop performance.

  • The Retroarms Trolley works in unison with the Flat-hop and Maple Leaf Super Macaron MR-Hops.

  • Features:
  • Modifications on the slide bars on each side compared to the original. This ensures a tighter fit onto the chamber to achieve an absolute Top-down-center push of force onto the R-hop patch while preventing any tilting.
  • The contact area of the front is increased by 0.5mm to cover most hop-up windows.
  • This ensures all areas of the R-hop patch are equally pushed down. In addition, this covers more of the chamber window for an increased air seal.
