Description
Proto Concept CB C03TC Forged Iron Heads
A standout performer in Golf Spy’s 2023 Best Players’ Irons, the Proto Concept CB C03TC Forged Iron Heads represent the next generation of performance cavity backs. Precision-forged from soft S20C carbon steel, each head features a CNC-machined undercut (#4–#7) and 3D CAD-optimized CG layout to deliver advanced shot-making capabilities with enhanced forgiveness. These are forged irons reimagined — pure feel, smart weighting, and Tour-proven shaping.
The C03TC’s modern cavity structure provides stability through the strike, while the progressive CG location makes long irons easier to launch and short irons deadly accurate. The carefully sculpted topline, parallel trailing edge, and sole design give intermediate and elite players a square setup and confident visual target. Designed to flow smoothly with other Proto Concept models, the C03TC excels both as a full set or in a custom combo build.
