  • 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
  • 3M adhesive incorporated at back on the M-nub for optimum contact on the Trolley foot. This is a strong bond, however, it is flexible and may be removed to be re-applied
The TDC (Top Down Centre) Trolley is designed for the Maxx 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.

Manufacturer: Airtech Studios


Compatibility: MAXX CNC Aluminum Hop-up Chamber ME - PRO & SPORT, MAXX CNC Aluminum Hop-up Chamber MI - PRO & SPORT, MAXX CNC Aluminum Hop-up Chamber SV - VFC SCAR-L/H, MAXX CNC Aluminum Hop-up Chamber ME - Umbrella Armory Ver., & MAXX CNC Aluminum Hop-up Chamber ME - EMG Ver.

NOTE: 2020 Versions of the TDC Trolley and M-nub will likely be in the color white due to manufacturing and supplier shortages of the black pellets due to the CV19. There is, however, no differences in functionality and performance.
