Sig Sauer Hexium Titanium, 5.56mm, Suppressor

Ultra-Light, Ultra-Quiet, Ultra-SIG.
The SIG Sauer HEXIUM556 TI Suppressor brings advanced engineering and cutting-edge suppressor design to your 5.56 NATO rifle. Built for performance-focused shooters who demand low back pressure, exceptional tone, and featherweight control, this titanium variant of the HEXIUM line represents the pinnacle of suppressor technology.

With an overall length of just 6.2 inches and weighing a mere 11 ounces, the HEXIUM556 TI is purpose-built for agility — whether you're running a short-barreled rifle, competition carbine, or a lightweight field gun. At its heart is a 3D-printed titanium core, leveraging SIG’s additive manufacturing and fluid dynamics modeling to optimize gas flow and minimize both blowback and decibels.

Designed to pair seamlessly across platforms, the suppressor includes a universal HUB Taper Direct Thread Mount (1/2x28) and a modular end cap for accessory attachments down the road. Its hex-patterned shell and black Cerakote finish offer enhanced grip, heat dissipation, and visual appeal.

From suppressed training to tactical operations, the HEXIUM556 TI is built to go the distance — and backed by SIG SAUER’s Infinite Guarantee™ for complete peace of mind.
