This TDC (Top Down Centre) Trolley is designed for the Maxx Hop-up chambers to incorporate the use of M-nubs with 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 ensures the patch can maximize its effect on the BB for the most stable and uniform spin for the much desired R-hop performance.

The trolley works well with flat hop, Maple Super Macaron and MR hops.

Features

• Optimised slide bars to prevent tilting and give a tighter fit
• Extended 5mm contact area to cover more hop windows improving air seal
• 3M adhesive to attach M-nub to trolley foot
