SureFire adapters provide reliable, precision mounting platforms for SureFire SOCOM Fast-Attach Suppressors and can also function as standalone muzzle devices. The SFCT-556-1/2-28 closed-tine adapter closely resembles a traditional birdcage flash hider, featuring wrench flats for easy installation. Like other SureFire SOCOM muzzle devices, this adapter is precisely machined from heat-treated stainless steel to resist gas and particle erosion. Additionally, these adapters use multiple bearing surfaces to ensure proper suppressor alignment every time. RSR -
