Information

5KU TDC (Top-Dead-Center) hop-up for a Hi-Capa is a precision upgrade that replaces the traditional side-dial adjustment system with a top-down screw mechanism.
Superior Accuracy: Provides a centered backspin for straighter and more predictable flight paths.
Heavy BB Compatibility: The granular screw adjustment makes it much easier to "zero" the pistol for heavier BB weights, such as 0.28g to 0.43g.
