SilencerCo Scythe-STM 30 Cal Modular Direct Thread Suppressor

The SilencerCo Scythe‑STM is a rugged, modular .30‑caliber suppressor engineered for durability, versatility, and proven performance across a wide range of rifles. Constructed from 17‑4 PH stainless steel and finished with a high‑temperature Cerakote, the Scythe‑STM combines full‑auto rating with a configurable length system that adapts to both long‑range precision rifles and short‑barreled platforms. The Bravo hub mounting system and included accessories provide straightforward attachment and field serviceability, while the integrated single‑port anchor brake helps manage recoil in a compact package.
