Airtech Studios ASG CZ Scorpion EVO Series Hop Up TDC Converter Kit The TDC (Top-Down-Centre) Trolley Converter is designed for ASG Scorpion Evos Hop-up Chamber to radically upgrade the applicable hop-up method inside the chamber. Good news this kit will NOT require any modification to any part of the Evo. 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 and there are third party chambers that can achieve this. However, switching to a third party chamber could carry a series of risks such as double BB feeding, misfeeding, and inconsistent air compression. That is the reason why we opted for an upgrade option for the original hop-up chamber that is specifically designed for the Scorpion Evo Original Chamber. 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.
