AIRTECH TDC Top-Down-Center Trolley for: Prometheus Rotary Chamber 

Types of Hop the Conversion Kit can be used for

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

Why TDC (Top-Down-Center)?
The idea of using a Top-down-center is a well sought after functionality in airsoft that maximizes the amount of friction allowed onto a BB round. As a result stable Hop friction and acceleration leading to tighter groupings.

M-Nub
We tested the performance of many types of M-nubs for its firmness, durability, and ability maintain its shape under intense pressure. We settled with a version that ticks all of these boxes. 2x M-nubs are included that covers the length of the hop-up window to maximize the amount of exposure onto the bucking and then BB. This ensures the most stable hop, while the BB accelerates through the hop mound/ Arch.
