Elite-Level Accuracy for Serious GBB Pistol Builds

The TTI Airsoft Infinity CNC TDC Hop Up Chamber is the ultimate internal upgrade for players seeking precision, consistency, and durability in their Umarex GHK G17 Gen5 MOS gas blowback pistol. Built specifically for this platform, the chamber ensures a tight, reliable fit that integrates seamlessly with your GBB’s internal components. Designed for competitive shooters and performance-driven loadouts, this hop-up unit significantly boosts your pistol’s range and accuracy with every shot. Whether you're on the field or at the range, it delivers the consistency required for serious play.

CNC 7075 Aluminum Construction for Maximum Durability

Crafted from high-strength CNC-machined 7075 aluminum, the TTI Infinity Hop Up is built to endure rigorous use without compromising performance. The one-piece design adds structural integrity and eliminates weak points common in multi-part chambers. This solid construction ensures the unit stays rigid under recoil and heat, offering long-term reliability even during high-tempo games or intense training. With its red anodized finish, it also adds a clean, professional look to your internal build.

TDC Adjustment for Pinpoint Hop-Up Control

Featuring a Top Dead Center (TDC) hop-up adjustment system, this chamber allows vertical, centralized pressure on your BBs for superior hop precision. The TDC system eliminates side-to-side inconsistencies, offering smoother, more repeatable hop-up adjustments that directly translate into tighter groupings and longer-range performance. This makes it ideal for players who demand fine-tuned control over BB flight paths—whether for CQB dominance or outdoor precision shots. Quick to dial in and highly responsive, the TTI TDC system redefines what’s possible from a GBB hop-up.
