Description
Achieve unrivalled precision and consistency with the TTI Infinity Hi-Capa/1911 CNC TDC Hop Up Chamber, available now from Defcon Airsoft, the UK’s leading online Airsoft retailer. Engineered from aerospace-grade 7075 aluminium alloy, this full CNC-machined hop-up unit transforms the performance of your Tokyo Marui-spec gas blowback pistol, delivering competition-grade accuracy and reliability shot after shot.
Built around the Top Dead Centre (TDC) adjustment system, this advanced hop-up chamber ensures perfectly vertical and even pressure on the BB. Because the force is applied directly above the bucking, the result is a consistent and stable backspin, which produces a flatter trajectory and enhanced range — allowing you to engage distant targets with precision and control.
Key Features
-
TDC Adjustment System: Provides direct, centralised pressure on the BB for superior consistency and improved flight path stability.
-
Full CNC 7075 Aluminium Construction: Ensures exceptional rigidity and dimensional accuracy since it resists deformation under stress.
-
Fine-Tuned Hop Control: Uses a micro-adjustable dial or 2mm Allen key for precise, repeatable tuning, even during extended skirmishes.
-
Enhanced Air Seal: The one-piece body with wrap-around bucking and a C-clip screw secures the inner barrel tightly, ensuring no loss of air pressure.
-
TM Spec Compatibility: Fits Tokyo Marui Hi-Capa 5.1, 4.3, Gold Match, and 1911 gas blowback pistol systems, as well as compatible clones.
-
Fixed Barrel Mounting: A reinforced screw locks the chamber assembly to the frame, reducing barrel wobble and maintaining zero alignment.
-
Sleek Finish: Coated in a refined black anodised finish for a durable, professional look in any custom pistol configuration.
The TTI Infinity Hop Up Chamber provides the mechanical stability and adjustment precision demanded by serious Airsoft competitors. Since its one-piece aluminium structure eliminates flex and ensures a perfect air seal, every shot remains consistent, powerful, and laser-straight.
This upgrade integrates seamlessly with TM-based Hi-Capa and 1911 builds, making it the ideal foundation for anyone seeking to extract maximum accuracy and range from their gas blowback pistol. When performance and reliability define your sidearm, the TTI Infinity CNC TDC Hop Up Chamber sets the benchmark for precision-engineered Airsoft upgrades.
