TDC Trolley with M-nub (R-Hop & Flat-hop) for Tokyo Marui SCAR H & HK417
The TDC (Top Down Centre) Trolley is designed for the Tokyo Marui SCAR H & HK417 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 improved trolley works in unison with the Flat-hop and Maple Leaf Super Macaron MR-Hops.
