Rearden FHD Flash Hider Features The Rearden FHD flash hider is machined with a .375 bore size to accommodate a wide range of calibers while effectively reducing visible muzzle flash during firing. Its design is built around compatibility with Rearden s Atlas Atlas XL and Plan B suppressor mounting systems giving shooters a flash hider that doubles as a quick attach platform for a suppressor when needed. The 1/2x28 thread pitch is among the most common on the market making the FHD a versatile fit across many 5.56 and similar caliber rifles. A PVD finish applied over the gunmetal colored base gives the part a hard scratch resistant surface that stands up to repeated suppressor mounting and removal. Because PVD coatings are applied through a vapor deposition process they bond tightly to the underlying metal resisting the wear and galling that can occur with simpler finishes over time. This durability matters most for shooters who frequently swap a suppressor between muzzle devices across multiple rifles. The gunmetal finish gives the FHD a subtle professional appearance that complements a wide range of rifle builds without standing out. The Rearden FHD Flash Hider in Gunmetal is available for sale at GrabAGun for shooters who want a dependable flash hider built around modern suppressor mounting standards.
