Radical Defense CS3, 30 Caliber, 5″ Length, 1.78″ Diameter, Black

The Radical Firearms CS-30 is a compact-form-factor .30 caliber suppressor — Radical’s CS (Compact Suppressor) series in the .30 cal configuration. The CS designation indicates a shorter body than the LS (Lightweight Suppressor) full-size series. Compact suppressors give up some internal volume — and therefore some sound reduction — compared to full-size cans, but the tradeoff is a shorter overall footprint on the muzzle. On a short-barrel rifle, a compact suppressor may be preferable to a full-size one: the shorter overall length keeps the system more maneuverable, while still delivering meaningful sound reduction.

The CS-30 covers the full .30 cal spectrum — 7.62 NATO, .308 Win, .300 Blackout, 6.5 Creedmoor, and everything smaller. At $849 with flash hider included, it’s the most cost-effective entry point in Radical’s .30 cal suppressor lineup.

FAQ — Radical CS-30

When should I choose the compact CS-30 over the full-size LS-3?

Choose the CS-30 (compact) when you want to minimize the added length on your rifle — particularly on short-barrel platforms or when maneuvering in tight spaces matters. Choose the full-size LS-3 when maximum sound reduction is the priority and the extra length is acceptable. Both use the same flash hider mount system and cover the same caliber range.
