The Infinity TDC Hop-up Chamber set by TTI Airsoft is designed for Tokyo Marui spec G-series GBB Airsoft pistols. CNC machined using high-grade aluminum, the hop-up chamber is a one-piece construction making it very robust yet lightweight. This chamber allows users to fine-tune their hop-up adjustments with the TDC (Top Dead Center) system, allowing for perfect vertical pressure to the bucking which in turn allows for a very stable and consistent hop-up effect. The hop-up chamber is a drop-in installation and does not require any modifications to install.
