The advanced SureFire 3-prong flash hider, which fits M4/M16 weapons and variants with 1/2×28 muzzle threads, features a patent-pending design that greatly reduces muzzle flash—typically greater than 99%—when compared with a plain muzzle. Boasting robust tines built to withstand the rigors of combat, the SF3P-556-1/2-28 also serves as a rock-solid mounting adapter for SureFire SOCOM Series 5.56 suppressors.

The 3-prong is one of our favorite muzzle devices. While it does bear the distinct “ring” after firing, you’ll stop noticing it pretty quickly.
