$299.85

HEX PWR Barrel Kit

The HK Army Hex PWR Barrel Kit is the next evolution of performance barrel systems combining precision machining, aggressive styling, and pro-level shot consistency into a single Elite platform.

Overview

Built from high-grade aluminum and finished with signature Hex-design windows and fractal CNC detailing, the Hex PWR system doesn't just perform, it visually stands apart. The precision-cut windowing on the barrel back and tip reveals the Vector Spiral PWR inserts beneath, giving the barrel a high-tech aesthetic that instantly elevates any marker.

At the core of the system are eight Vector PWR control inserts with exterior spiral fluting and each micro-honed for maximum smoothness, optimal ball stabilization, and consistency across all paint sizes. Paired with the Hex PWR tip's tuned porting, you get a quieter shot, better grouping, and a true competitive advantage.

Packaged inside the custom HK Army EXO Hard Shell Barrel Case, every component is protected, organized, and ready for field use.
