The SilencerCo Scythe STM (Stainless Steel Modular) is a durable, modular rifle suppressor engineered from 17-4 stainless steel for long service life and corrosion resistance. It supports a wide range of calibers from .223 REM/5.56 NATO up to .300 RUM and allows quick changes between a longer configuration for maximum sound reduction and a shorter configuration for improved maneuverability. Optimized internals reduce point-of-impact shift, the included Anchor Brake reduces recoil, and compatibility with SilencerCo s Bravo/HUB accessories provides extensive customization options for hunting, precision, and tactical use.
