Airtech Studios KWA QRF MOD 1 Rotary Hop Up TDC Converter Kit

The TDC (Top-Down-Centre) Trolley Converter is designed for the KWA QRF MOD2 Rotary Hop-up Chamber to radically upgrade the applicable hop-up inside the 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-Centre)?

The idea of using a Top-down-centre is a well sought after functionality in airsoft that maximizes the amount of friction allowed onto a BB round and there are third part 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 KWA QRF MOD Series replicas.

M-Nub

Airtech Studios 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 these boxes.

Gun Modification

This is a drop in upgrade and modification to any part of the QRF MOD1 is not required, however different models using the same rotary chamber may require some modification on the outer barrel to fit. See Manual or contact us for more information.
