SureFire | Flash Hider / Silencer Adapter | 223 Rem | 5.56 NATO

The SureFire SF3P is a three‑prong SOCOM Fast‑Attach flash hider and suppressor adapter. Patented tines typically cut more than 99% of muzzle flash versus a bare muzzle. Heat‑treated stainless steel, DLC coating, single‑point‑cut barrel threads, multiple bearing surfaces so the suppressor sits concentric and the tines do not ring inside the can. Labyrinth seals at the lock ring. Inspected for concentricity. Not compatible with pre‑SOCOM Fast‑Attach suppressors or adapters. Family length 2.6 inches, 3.9 ounces. This SF3P‑556‑1/2‑28 is 5.56 mm on 1/2‑28 threads.
