Product Overview

This TDC (Top-Down-Centre) Trolley Converter is designed for the Prometheus Wide Use Metal Chamber, offering a major improvement in the hop adjustment.

The kit can be used in conjunction with all bucking types and also works perfectly for R-Hop & Flat-hop setups. The trolley system applies hop directly downwards for the most consistent pressure distributed onto the BB. As a result, accuracy increases over longer distances.

The TDC (Top Down Center) is a well sought after function in airsoft that maximises the amount of friction applied onto the BB, resulting in tighter groupings.

The included M-nubs were developed through extensive testing to optimise the firmness and durability. They cover the length of the hop up window for consistent maximum performance.

NOTE: this kit will require modification to the outer barrel of your airsoft replica, however, is straightforward. Full instructions on how to modify are included in the instruction manual.
