Sig Sauer Hexium 300 Titanium Suppressor
The Sig Sauer Hexium 300 is a versatile multi-caliber suppressor engineered to deliver low back pressure, refined sound characteristics, and flexible mounting options across compatible firearm platforms. Built using SIG SAUER's advanced additive manufacturing technology, the Hexium combines a 3D printed titanium/Inconel core with sophisticated internal geometries designed around efficient gas management.
Measuring 8.95 inches long with a 1.75-inch diameter and a weight of approximately 15 ounces, the Hexium 300 balances substantial suppression volume with lightweight titanium construction. Its exterior is protected by a durable black Cerakote finish and features the distinctive external hexagonal pattern that gives the Hexium family its recognizable appearance.
Low Back Pressure Internal Design
SIG SAUER engineered the Hexium around a low back pressure internal architecture. The suppressor's 3D printed core allows SIG to incorporate complex internal geometries designed to manage expanding gases while reducing the amount of pressure directed back toward the host firearm.
This design combines gas management with the sound performance SIG developed the Hexium line to deliver, creating a suppressor intended for shooters looking for both refined suppression and comfortable operation.
3D Printed Titanium/Inconel Core
The Hexium uses SIG SAUER's advanced additive manufacturing process to create a 3D printed titanium and Inconel core. Additive manufacturing allows internal structures and gas pathways to be produced that would be difficult or impossible to achieve using conventional machining techniques.
The result is a suppressor that combines lightweight titanium construction with strategically utilized Inconel and complex internal geometry designed for durability and performance.
HUB Taper Direct Thread Mount
For mounting versatility, the Hexium 300 is furnished with SIG SAUER's HUB Taper Direct Thread Mount. The included configuration provides a straightforward mounting solution while the HUB-based design gives the suppressor additional flexibility for compatible mounting systems.
This configuration includes a 1/2x28 direct thread mount.
Modular End Cap Accessory System
SIG SAUER also incorporates a modular end cap accessory mounting system into the front of the Hexium. This allows compatible end cap accessories to be incorporated into the suppressor configuration and expands the versatility of the overall platform.
