The Hexium 300 utilizes a hybrid 3D printed titanium and Inconel core to achieve a balance between lightweight maneuverability and extreme thermal durability. Titanium provides weight savings and corrosion resistance, while Inconel offers superior performance under sustained fire and high-pressure cycles. This internal architecture is specifically engineered for low back pressure operation, which helps mitigate gas blowback into the shooter’s face when used on semi-automatic systems, while preserving consistent cycling reliability.
Externally, the Hexium 300 features a rugged hexagonal relief pattern milled into the surface of the suppressor. This design enhances both heat dissipation and grip during installation or removal. Finished in matte black Cerakote, the exterior is resistant to abrasion, solvents, and high temperatures, ensuring long-lasting visual and functional integrity. The suppressor is optimized for .300 AAC Blackout, offering superior decibel reduction across subsonic and supersonic ammunition types.
Installation is handled via the HUB-compatible taper direct thread mount system. This ensures secure barrel engagement and consistent alignment, which translates into improved accuracy and point-of-impact retention. Additionally, the Hexium 300 includes an end cap accessory mounting system, allowing the shooter to swap end caps for caliber-specific tuning or flash mitigation depending on operational needs.
