The AAC 7.62-SDN-6 is a compact fast-attach sound and flash suppressor for 7.62x51mm and 300 AAC BLACKOUT (7.62x35mm) weapons. It is 1.25” shorter than the 762-SD and features a fully welded all-Inconel® baffle stack and front end cap to maximize durability on select fire 7.62mm SBRs. The AAC 762-SDN-6 also functions as a superb multi-caliber suppressor for multiple hosts, providing excellent performance on 7.62 NATO, 300 AAC, 6.8 SPC, 6.5, and 5.56mm NATO. When employed on a 300 AAC BLACKOUT, the overall SPL of 126 dB with subsonic ammo is quieter than the 9mm HK MP5-SD.
