SureFire WARCOMP-556-CTN is a closed tine flash hider that is
neutrally ported to aid in recoil management. Compared to that of the open tine
adapters, the WARCOMP-CTN for 5.56 caliber weapons mimics that of a traditional
birdcage flash hider along with being a rock solid mounting option for SOCOM
Series Fast-Attach® suppressors. The muzzle device also has wrench flats
machined into the sides of the adapter for aid in installation. The closed tine
option does not have as much flash reduction to that of the open tine adapter
but still is very capable.
