Radical Defense LS3TI, 30 Caliber, 7.5″ Length, 1.78″ Diameter, Black

The Radical Firearms LS-3TI is a full-size .30 caliber suppressor in titanium — Radical’s Lightweight Suppressor series in the .30 cal configuration, built with titanium construction for a significant weight reduction over steel. The LS designation indicates full-size (versus CS compact), and the TI designation means titanium baffles/body. Titanium suppressors provide a meaningful weight advantage over steel — typically 30–40% lighter for equivalent volume — at a modest cost premium. On a .308 AR or bolt gun, the difference between a steel and titanium suppressor of similar size can be 4–8 ounces, which matters for a suppressor that lives permanently on the muzzle of a rifle carried in the field.

The .30 caliber rating covers 7.62 NATO, .308 Winchester, .300 Blackout (300 BLK), and any caliber with a bore diameter at or below .308″. This makes the LS-3TI one of the most versatile suppressors Radical offers — one suppressor for multiple hosts across your 30-cal collection.

FAQ — Radical LS-3TI

What is the advantage of titanium over steel in a suppressor?

Titanium is approximately 40% lighter than steel at equivalent strength. In a suppressor, this translates to less muzzle-heavy feel, less fatigue when carrying suppressed, and better balance on precision rifles. The tradeoff is that titanium is harder to machine and costs more. For sustained high-volume fire, steel tends to be more durable. For hunting, field carry, or moderate-volume range use, titanium’s weight advantage is a real benefit.
