TDC Trolley with M-nub (R-Hop & Flat-hop) for Retroarms Hop-up Chamber Cheap

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 is 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.
