Radical Defense LS-5Ti 5.56mm Suppressor | 1/2×28 LS5TI-FDE

The Radical Defense LS-5Ti is a purpose-built suppressor for 5.56mm platforms, constructed from Ti64 and finished in a proprietary I/R non-reflective coating. The 7.5 inch length and 1.75 inch diameter balance mitigation and handling for duty, training, and precision range work. The design emphasizes pressure stabilization and reduced back pressure through forward venting and breathable technology, and it is rated for sustained full-automatic fire.

Built around lightweight titanium and a robust monolithic form, the LS-5Ti provides mitigation of sound, flash, and thermal signature while prioritizing durability and sustained use. The forward-venting geometry and pressure-stabilizing features reduce felt back pressure to the host weapon, making it suitable for extended range sessions and professional use. Its FDE finish and non-reflective coating are intended for low-visibility profiles in field conditions.

Users and descriptions have praised the LS-5Ti for its durability and for providing effective sound, thermal, and flash mitigation while remaining rated for sustained full-automatic fire.
