Product Description

⚠ NFA ITEM — SUPPRESSOR
This is a federally regulated suppressor (silencer) under the National Firearms Act. Purchase requires a BATFE Form 4 transfer, background check, and $200 NFA tax stamp — now $0 under the One Big Beautiful Bill Act (OBBBA). Buyer must be 21+, a US citizen, reside in an NFA-legal state, and have no disqualifying criminal history. Allow about two weeks or less for ATF approval. Western Sport handles all paperwork — call 817-393-4000.

The Radical Firearms CS-5TI is a compact 5.56 suppressor in titanium — Radical’s CS (Compact Suppressor) series in the .556 caliber configuration, built with titanium for weight savings. The combination of compact body length and titanium construction makes the CS-5TI the most portable suppressor in Radical’s 5.56 lineup. On a 10.3″ or 10.5″ SBR, a compact lightweight titanium suppressor is the practical choice — the muzzle-forward weight stays manageable and the overall system remains maneuverable. The CS-5TI is sized for the shooter who wants to suppress their short-barrel AR without turning it into a full-size suppressed rifle in terms of feel and handling.

FAQ — Radical CS-5TI

Is the CS-5TI 5.56-only or can it handle other calibers?

The CS-5TI is rated for 5.56 NATO/.223 Rem and smaller bore diameter calibers. It should not be used on .30 caliber rifles (.308, 300 BLK, etc.) — for those, Radical’s LS-3, LS-3TI, CS-30, or CS-30TI are the correct choices.

Recent eForm 4 approvals have been coming back in about two weeks or less — see our NFA wait times guide for current figures.
