This TDC (Top Down Centre) Trolley is designed for the Maxx Hop-up chambers to incorporate the use of M-nubs with the ER-Hop (elongated R-hop patches, typically of 6mm in length for long-distance shots). The longer patch gives an improvement in accuracy and consistency from shot to shot, typically for sniper/DMR builds.

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
