SureFire designs and manufactures a wide variety of firearms accessories, from weapon lights to suppressors. The leading manufacturer of rugged, powerful lights, SureFire is synonymous with excellence in handheld illumination.

The 3 Prong Flash Hider/Suppressor Adapter is an advanced flash hider compatible with AR-15/M16 weapons and variants with 1/2x28 muzzle threads. Featuring a design that greatly reduces muzzle flash and serves as a rigid mounting adapter for SureFire SOCOM Series 5.56 Fast-Attach suppressors. 

Precision machined from heat-treated stainless steel bar stock, this adapter includes high-precision single-point cut threads for optimum thread interface, finished with a Black Ionbond DLC coating for maximum corrosion protection. Designed with multiple bearing surfaces ensuring proper suppressor alignment. A rear labyrinth seal minimizes potential carbon buildup in the indexing system, facilitating removal after extended firing. Each flash hider is individually inspected for concentricity and alignment.

NOTE: SureFire SOCOM Series Fast-Attach sound suppressors, flash hider/suppressor adapters, and muzzle brake/suppressor adapters are not compatible with previous SureFire Fast-Attach sound suppressors, muzzle brakes, or flash hiders.
