Item # 289603 Style HEXIUM556 UPC 798681731671 Condition New Manufacturer [Sig Sauer](https://www.kygunco.com/brand/sig-sauer) Model Hexium Caliber 5.56 NATO Weight 11 oz Action Silencer The Hexium 556 is part of Sig Sauer’s next-generation suppressor technology, leveraging additive manufacturing to create complex internal geometries for superior gas flow and acoustic performance. Its monolithic titanium core is printed as a single piece, eliminating internal welds and weak points. This design not only reduces weight, coming in at just 11 ounces, but also increases durability under extreme heat and pressure commonly encountered during rapid-fire strings or full-auto use. At the heart of the system is Sig’s HUB-compatible taper mount. This 1.375x24 thread pattern allows for modular mounting compatibility with a wide range of suppressor mounts and muzzle devices. Out of the box, the suppressor is configured with a 1/2x28 direct thread adapter that provides a secure and precise barrel interface, ensuring reliable alignment for accuracy-focused applications. The taper lock further enhances thermal and retention characteristics under heavy use. Externally, the suppressor body is finished in a matte black, corrosion-resistant coating and features clean, functional lines. The front is designed to accept interchangeable end caps, allowing users to fine-tune back pressure and sound performance. The Hexium 556 is purpose-built for tactical shooters, law enforcement, and high-volume range use, offering a balance of suppression, weight savings, and ruggedness in a compact footprint. **Features** - Exceptionally quiet performance with refined baffle geometry - Low back pressure design for cleaner operation and reduced gas-to-face - HUB compatible with Direct Thread steel mount - Tool-less modular end cap accessory interface - External hex pattern with black hi-temp Cerakote finish - 3D-printed titanium suppressor body - Infinite Guarantee **Specifications** - Model: EXIUM556 - Caliber: 5.56 NATO - Material: Titanium - Diameter: 1.75 in - Overall Length: 6.2 in (157 mm) - Weight: 11 oz (312 g) - Attachment Type: HUB compatible, Direct Thread steel mount - Thread Pitch: 1/2×28 - Finish: Black hi-temp Cerakote Shop with KYGUNCO for the best selection, competitive pricing, and exceptional customer service.
