The Radical Defense LS3Ti is the titanium 7.62mm suppressor in the LS3 family (brand part no. LS3TI). It is made from Ti64 and weighs 12.75 ounces, against 17.5 ounces for the Haynes 282 LS3. Radical Defense optimizes the LS3 for .300 Blackout systems and bolt-action precision rifles, and its Breathable Technology reduces blowback and back pressure. The monolithic body resists heat, corrosion and salt air, and the infrared-suppressive coating cuts near-IR signature. It mounts on a 1.375-24 hub interface with a KFM flash hider threaded 5/8×24.
