Griffin Armament’s dedication to the never-ending pursuit of providing maximum value to the customers knows no bounds. The development of the newest silencer in the GATE-LOK line is no different. The Griffin Armament 30SD-K was born from multi-level customer feedback that reported the desire for a shorter .30 caliber QD silencer. Pursuing maximum performance the design team incorporated Griffin Armament’s patented HEDP™ Baffle technology into the 30SD-K. The 30SD-K offers an incredible 127dB 300BLK subsonic sound signature 136dB on 5.56mm and 138dB 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 30SD and M4SD mounts. 5.56mm firearms are supported with this suppressor via use of any of our M4SD mounts in addition to compatible A2 compensators.
