EOTech 5.56NATO Suppressor Ready Flash Hider 1/2x28 9-EOT-DCLB-KFM-556 UPC 672294470670
Product Description
The EOTech 5.56NATO Suppressor Ready Flash Hider (9-EOT-DCLB-KFM-556) is a precision-engineered hybrid muzzle device designed for 5.56mm NATO and .223 Remington rifle platforms. Threaded in standard 1/2x28 TPI, this heavy-duty flash hider combines exceptional unsuppressed muzzle flash elimination with a fast-attach mounting interface for compatible quick-detach (QD) suppressor systems.
Precision CNC-machined in the USA from heat-treated alloy steel and finished with a resilient black nitride coating, the 9-EOT-DCLB-KFM-556 features open-prong geometry designed to disrupt signature combustion flash during low-light and night operations. The external taper and locking collar surfaces provide a repeatable, gas-tight seal when mounting compatible silencers—minimizing point-of-impact (POI) shift and preventing carbon fouling from binding attachment threads.
Whether deployed on AR-15 carbines, short-barreled rifles (SBRs), or duty rifles, the EOTech 5.56mm Suppressor Ready Flash Hider delivers military-grade durability, reduced night signature, and seamless silencer mounting for hard-use tactical applications.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits rifle barrels chambered in 5.56mm NATO / .223 Rem and smaller .22-caliber variants utilizing standard 1/2x28 TPI threads. Serves as a direct fast-attach mounting base for compatible EOTech/KFM platform silencers.
- Perform a complete firearm safety check: drop the magazine, lock the bolt rearward, and visually inspect the chamber to verify zero live rounds are present.
- Thoroughly clean the 1/2x28 barrel muzzle threads using a wire brush and solvent to remove oil, carbon, or thread locker debris.
- Apply a small drop of high-temperature threadlocker (Rocksett recommended for suppressed use) to the clean barrel threads.
- Thread the flash hider onto the barrel shoulder by hand to ensure no cross-threading occurs.
- Torque the device to 20–30 ft-lbs using an open-ended armorer wrench applied to the wrench flats.
- Allow threadlocker to cure for 24 hours before mounting your silencer and conducting an alignment rod check prior to live fire.
