SureFire’s 3P Eliminator three-prong flash hider fits AR-10 weapons and variants with 5/8×24 muzzle threads. It features a patent-pending design that greatly reduces muzzle flash when compared with a plain muzzle. The body is made from US mill-certified steel bar stock including high-precision single-point cut threads for optimum thread interface the muzzle brake has a black Melonite finish that provides maximum protection under harsh environmental conditions and facilitates cleaning even after extreme use. NOTE: This model cannot be used to mount SureFire SOCOM suppressors.
