ST Series Suppressors

Built using a 3D-printed monolithic design from Haynes® 282, a nickel-based superalloy renowned for its high-temperature strength and fatigue resistance. The ST Series Suppressor models are rated for continuous full-auto fire, maintaining superior sound suppression, thermal control, and flash mitigation in the most demanding environments.

For shooters prioritizing reduced weight and balance, the Ti64 Titanium variant offers exceptional agility without compromising accuracy. This configuration provides lightweight reliability in a compact form. Full-auto use is not recommended for Titanium models.

Advanced Flow Dynamics

Each suppressor incorporates a forward-venting monolithic core with an integrated flash hider. The design stabilizes cyclic rate and effectively reduces back pressure through optimized gas assist ports—enhancing weapon reliability and shooter comfort.

Protected by AT-1420 AlphaShield™ Elite, a near-infrared signature-reducing, non-reflective coating.
