Airtech Studios TDC M-Nub Trolley for MAXX Hop ChamberCompatible with MAXX ME PRO Series (NOT newer PRO M4A, M4i, M4P, or M4W Units)
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.
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.
- 3M adhesive incorporated at back on the M-nub for an optimum contact on the Trolley foot. This is a strong bond, however, is flexible and may be unstocked to be re-applied.
 The TDC trolley is compatible with all M4 and Scar Maxx Hop-up chambers listed below.

Yes this is a great upgrade for the maxx hop up units depending on the application. Through testing I found that these nubs work great with the new maple leaf macaron buckings and any barrel with a good square cut window. Lambda, madbull, edgi, zci, prometheus. One combination I did was the elvish tac r hoped zci barrel and I had poor results. From what I could see the elvish tac r hop patches are made from a very stiff rubber and what happened was that it would cause the 3m patch on the m nub and make it tilt so instead of a nice flat surface it cause it to be like an old school bucking with one rounded mound in the barrel window. From what I could tell these would work great with an r hop barrel with an extended window and the surgru black material like the Umbrella armory r hop kits.
