TTI Gen4 G17 TDC Hop Up Chamber

TTI-P0044

The TTI Infinity TDC Hop Up Chamber is a precision CNC machined upgrade for the Tokyo Marui Gen4 G17 gas blowback pistol. TDC (Top Dead Centre) adjustment lets you fine-tune hop both vertically and horizontally, giving you a more consistent backspin and a flatter, more accurate trajectory than the standard chamber allows.

Designed as a direct replacement, it is intended to drop into the compatible Marui platform with no permanent modification. We recommend installation by someone confident with gas pistol maintenance to get the best results. The result is sharper shot-to-shot consistency and easier hop tuning out on the field.
