The Radical Firearms LS-5 is a full-size 5.56 NATO suppressor — Radical’s Lightweight Suppressor series in the .556 caliber configuration. The LS designation indicates this is the full-size variant (as opposed to the CS Compact Suppressor series), providing maximum volume for sound reduction. 5.56 NATO is one of the most popular suppressed calibers in the civilian market — affordable ammunition, widely available hosts, and an excellent noise reduction profile make suppressed 5.56 shooting one of the most accessible NFA experiences available.
At $899 with a flash hider included, the Radical LS-5 is positioned as a legitimate entry into quality 5.56 suppression at a price point that makes the total NFA investment (suppressor + Form 4 + $0 OBBBA stamp) substantially under $1,000. Radical Firearms builds in Houston, Texas, and the LS-5 reflects their philosophy: a quality, American-made suppressor at a price that doesn’t require a premium-rifle budget.

FAQ — Radical LS-5 5.56
How does the LS-5 compare to the CS-5TI in Radical’s lineup?
The LS-5 is the full-size Lightweight Suppressor and the CS-5TI is the Compact Suppressor in titanium. Full-size typically provides better sound reduction due to larger internal volume; the compact titanium version trades some reduction for shorter overall length and lighter weight. For a dedicated home/range suppressor, the full-size LS-5 usually produces better numbers. For a suppressor that will live on a shorter-barrel gun and be carried regularly, the CS-5TI may be preferable.
