b'3 0 S D KThe Griffin Armament 30SD-K was born from customer feedback, the desire for a shorter multi-cal .30 caliber GATE-LOK suppressor. Pursuing maximum performance, the design team incorporated Griffin Armaments patented ECO-FLOW baffle technology into the 30SD-K. The 30SD-K offers an incredible 123dB 300BLK subsonic sound signature, 133dB on 5.56mm, and 139dB on .308. The 30SD-K offers users a wide range of platform coverage from 7.62mm, 300BLK, 6.8spc, and 5.56mm using our variety of GATE-LOK muzzle devices. Firearms chambered in 5.56mm are supported with this suppressor via use of any of our GATE-LOK mounts, in addition to compatible A2 compensators.'
