Radical Defense LS-3 | .30 Cal Suppressor | Black

The Radical Defense LS-3 is a .30 caliber (7.62 mm) monolithic rifle suppressor built for sustained use and thermal durability. It uses a nickel-based Haynes 282 alloy and a proprietary IR non-reflective coating for increased corrosion and heat resistance. The LS-3 features a forward-venting, taper-mount architecture designed to reduce back pressure and manage cyclic rate for sustained-fire applications.

Common applications include sustained-fire training and long-range precision or tactical shooting where sound, flash and thermal signature mitigation are required components of system performance.
