AAC SDN-6

Manufacturer: Advanced Armament Corp.
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. 1.25” shorter than the 762-SD™, it features a 360-degree fully welded Inconel® baffle stack and front end cap to maximize durability on select fire 7.62mm SBRs. The 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.

This can is certainly not the lightest, but the price ($630-ish) is right, and the performance is top tier. Muzzle mounts were quite pricey but have come down a bit as of late.  But the cost of running multiple weapons/uppers still adds up quick when you need to put one of their 51-toothed mount (brake) on each barrel at around $125 per...I think I've got about 9 various barrels (308/300AAC/223) sporting one of the various brake options. [Note: I despise the original 51T flash hider mount.  It's a 3-pronged tuning fork...which when shot w/out the can delivers a "twang" which is more annoying to me than nails on a chalkboard!]
