TTI - INFINITY TDC Hop Unit for Umarex (VFC) G-series - Black

TTI Infinity TDC Hop Unit for Umarex (VFC) G-series

The TTI Infinity TDC Hop Unit for Umarex (VFC) G-series is a one-piece, full CNC machined hop-up chamber built to replace the fragile factory part. Its TDC (Top Dead Centre) design pushes hop pressure straight down the centre of the BB for more consistent backspin and a flatter, more accurate trajectory.

Cut from a single solid billet, it removes the flex and wear of the stock plastic chamber so your hop setting stays locked in shot after shot. A simple drop-in upgrade for VFC and Umarex G-series gas blowback pistols.

Key features:

One-piece full CNC machined construction

TDC top-down hop adjustment for accuracy

Replaces the weak factory plastic chamber

Consistent, repeatable hop settings

Compatible with VFC / Umarex G19X, G19 Gen4, G17 Gen5 and G45
