The SIG SAUER HEXIUM 556 (Titanium) suppressor is engineered for serious shooters demanding high performance with minimal compromise. Built around a 3D-printed titanium core, the HEXIUM 556 weighs 11 oz and measures 6.2 in overall length with a 1.75 in diameter. Its internal geometry is optimized for low back pressure and sound suppression, delivering crisp, clean tonal qualities across semi-auto and full-auto platforms. Out of the box it ships with a 1/2-28 direct-thread mount that is compatible with industry-standard HUB mounts, allowing you to use your favorite quick-detach 1.375x24 HUB mounts.
Three flagship features define this suppressor’s advantage: (1) Optimized for Sound & Low Back Pressure — the internal design minimizes gas blowback while maximizing acoustic efficiency; (2) HUB-Compatible Mount — the taper mount system allows quick swaps and cross-platform compatibility with HUB-style mounts; and (3) Modular End Cap for Additional Accessories — the front end cap can be interchanged or upgraded to tune performance or add attachments. These features combine to make the HEXIUM 556 Titanium a versatile, high-end suppressor suited for tactical, precision, and duty use.
