Unlike closed-end flash hiders prone to erosion, this unit features an open-end 3-prong design that is inherently stronger than 4-prong counterparts and resists wear even under heavy use. Constructed from aerospace-grade steel alloy and finished in AAC’s proprietary SCARmor corrosion-resistant coating, this flash hider is built for demanding operational environments. Rocksett threadlocker is included for reliable mounting.
