Surefire SOCOM closed-tine flash hider SFCT-556-1/2-28

Charlie's likes this flash hider a lot.  Great for pinning a 14-1/2" barrel, and accepts a SOCOM suppressor, so bonus !  Also, a little hard to find.

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 Surefire Closed Tine adapters closely represents a traditional birdcage flash hider along with having wrench flats for ease of installation. Just like the other SOCOM muzzle devices, this adapter is precision machined from heat-treated stainless steel which is highly resistant to gas and particle erosion. Additional these adapter utilize multiple bearing surfaces to ensure proper suppressor alignment every time.
