SureFire® – Closed-Tine Flash Hider

SureFire adapters serve as rock-solid, precision mounting platforms for SureFire SOCOM Fast-Attach Suppressors, as well as, serving as a standalone muzzle device. The SFCT-556-1/2-28 closed-tine adapter closely represents a traditional birdcage flash hider, with wrench flats for easy installation. Just like other SureFire SOCOM muzzle devices, this adapter is precision machined from heat-treated stainless steel which is highly resistant to gas and particle erosion. Additionally, these adapters utilize multiple bearing surfaces to ensure proper suppressor alignment every time.
