SilencerCo Scythe STM - .30 Cal Suppressor

Push your rifle’s performance further with the SilencerCo Scythe STM .30 Cal Suppressor—a rugged, modular suppressor engineered for shooters who demand durability, adaptability, and precision across a wide range of calibers. Built as a stainless steel counterpart to the Scythe-Ti, the Scythe STM is designed to thrive under harder use, offering enhanced strength without sacrificing the refined suppression performance the Scythe series is known for.

From .223/5.56 platforms to hard-hitting .300 RUM setups, this versatile suppressor delivers consistent sound reduction and reliability across multiple rifle configurations. Its modular design allows you to tailor your shooting experience—run it short for improved maneuverability or extend it for maximum sound suppression when precision and stealth matter most.

Crafted from durable 17-4 stainless steel, the Scythe STM is built to handle demanding conditions while maintaining consistent performance. The included Single-Port Anchor Brake further enhances recoil control and shooting stability, giving you faster follow-up shots and better overall handling.

Whether you're at the range, dialing in long-range precision, or setting up a multi-caliber system, the Scythe STM offers the flexibility and toughness to meet your needs—shot after shot.
