The Daniel Defense SoundGuard SG-30 (brand part no. 0614005098), powered by KGM Suppressors technology, is a .30-caliber suppressor built around cutting-edge gas-flow dynamics that eliminate over-gassing and direct most gases forward rather than back into the shooter’s face. Daniel Defense threads the SG-30 in a 5/8-24 pattern, reducing toxic gas blowback so shooters can focus on putting shots on target. The SG-30 favors .30-caliber shooters who want reduced gas blowback from a KGM-powered design.
