Surefire Eliminator Fh 5.56mm 1/2x28

The Surefire Eliminator FH 5.56mm 1/2x28 is a flash hider engineered for 5.56 NATO / .223 Remington rifles with 1/2x28 barrel threads. Surefire's Eliminator design prioritizes flash signature reduction across the visible and near-infrared spectrum—a critical advantage for operators working in low-light environments, tactical operations, or training scenarios where muzzle flash discipline matters. The 1/2x28 thread pitch is the standard configuration for modern AR-15 upper receivers and 5.56 carbines, making this hider a direct-fit solution for most semi-automatic patrol rifles and M4-pattern platforms without adapter sleeves.

Flash reduction performance is the primary specification driving purchase decisions in this category. Surefire's proven baffle design suppresses muzzle flash visible to the naked eye and thermal imaging systems—reducing the shooter's visibility signature to potential threats or opposing force observers. The hider's geometry also manages recoil impulse and blast concussion in a direction that does not significantly degrade the shooter's ability to stay on target during rapid fire. Installation is straightforward: the 1/2x28 threads engage directly with barrel extensions on AR-15 platforms, requiring no additional adapters or modifications.

This configuration serves law enforcement carbine teams, military rifle shooters, and civilian tactical trainers who operate under low-light protocols or require reduced muzzle signature for mission consistency. Operators conducting CQB entries, night raids, or range work where flash discipline impacts performance benefit most from this flash hider's signature-reduction profile. Surefire products have established themselves in professional end-user communities through consistent performance in field conditions—a reputation earned through widespread adoption by federal, state, and local armed services.

The 5.56 NATO cartridge class remains the standard rifle round for modern tactical platforms, and flash hiders rated specifically for this caliber are engineered to handle the full pressure envelope of standard and military-spec ammunition. The 1/2x28 thread size is optimized to balance interface strength with the typical barrel diameter of mid-length and carbine-length AR-15 uppers, ensuring consistent repeatability and durability across thousands of rounds.
