Get more accuracy over longer distances with the Airtech TDC (Top Dead Centre) Trolley Converter.

The trolley system functions perfectly with R-Hop and Flat-hop setups by applying consistent downwards pressure onto the BB. The longer patch improves accuracy and consistency from shot to shot, typically for sniper DMR builds.

This converter fits onto the stock hop chamber retaining the standard adjustment functionality. Once installed you have a fully functional TDC hop while keeping the original hop-up unit designed for the gun preventing misfeeding or double feeding which can occur with aftermarket hop-up units.
