AAC Blackout Flash Hider 90T 7.62mm 5/8-24 SR Series Only

The AAC Blackout Flash Hider 90T 7.62mm 5/8-24 threaded flash suppressor is purpose-built to eliminate muzzle flash across subsonic and supersonic 7.62×51mm NATO and 7.62×39mm platforms. Advanced Armament Company's open-end 3-prong design delivers effective flash signature reduction even on short-barrel configurations where closed-end suppressors prove problematic. The 90-degree tooth geometry—unique to AAC's Blackout lineage—provides superior durability compared to conventional 4-prong units by distributing thermal stress more effectively across the prong structure.

Manufactured from high-strength aerospace-grade steel and finished with AAC's proprietary SCARmor hard-coat corrosion-resistant finish, this flash hider withstands harsh field conditions without degradation. The open-end design eliminates the erosion wear patterns that plague closed-end suppressors operating at sustained fire rates or in sand/dust environments. Weighing just 0.32 lbs, the compact 3.75-inch length minimizes impact to your weapon's balance and sight radius. Installation utilizes standard 5/8-24 threading—the mil-spec standard for 7.62mm rifle platforms—with Rocksett threadlocker included to ensure zero shift under sustained firing cycles.

This flash hider serves operators running precision rifle builds, patrol carbines, and designated marksman systems where muzzle signature control matters without the added weight and regulatory complexity of suppressor registration. The SR Series designation indicates compatibility with monolithic upper receiver platforms and free-floating barrel configurations where tolerances demand precision engineering. Recommended for shooters operating in low-light environments, mounted optics users prioritizing sight picture preservation, or operators downrange from support personnel where flash discipline improves situational awareness.
