The Griffin Armament 30SDK is a compact 7.62mm suppressor built for shooters who need effective sound reduction without the bulk. Designed specifically for .300 BLK platforms and multi-caliber use, this short silencer delivers serious performance in a package that doesn't sacrifice handling or maneuverability. Whether you're running subsonic rounds through a short-barreled rifle or shooting supersonic loads, the 30SDK brings proven Griffin engineering to the table—including their patented HEDP baffle technology and the dependable Gate-Lok quick-detach mounting system.
What sets the 30SDK apart is its focus on the details that matter in the real world. The mounting interface tolerances are ground to ten-thousandths of an inch, which means point of impact shift stays minimal and repeatable—not the drift you'd see with loosely fit competing systems. The Gate-Lok interface itself is wear-resistant by design; unlike ratcheting mounts that degrade with use, this system maintains its integrity through hundreds of attach-detach cycles. High-temperature Cerakote over 17-4PH stainless steel means the suppressor handles full-auto strings and extended shooting without reliability concerns.
The 30SDK ships with a 30SD muzzle brake mount, a shim set for fine-tuning, and a protective silencer pouch. If you're building a modular .30 caliber ecosystem, this suppressor plays well with Griffin's 30SD and M4SD mounting lineup, and with standard A2 compensators on 5.56 platforms. At 6.6 inches and 17.8 ounces, it's engineered to stay in your hands longer without the fatigue of a full-size can.
| Caliber | 7.62mm (.300 BLK, 6.8 SPC, .308 Winchester compatible) |
| Overall Length | 6.6 inches |
| Diameter | 1.5 inches |
| Weight | 17.8 ounces |
| Material | 17-4PH stainless steel |
| Finish | High-temperature Cerakote |
| Construction | TIG fusion welded with wire EDM precision |
| Mounting System | Gate-Lok quick-detach interface |
| Mount Compatibility | 30SD and M4SD mounts; USGI spec A2 compensators (5.56mm) |
| Included | 30SD muzzle brake mount, shim set, silencer pouch |
The 30SDK is rated for 7.62mm cartridges including .300 BLK, 6.8 SPC, and .308 Winchester. It's also compatible with 5.56mm platforms when paired with appropriate M4SD mounts and compatible A2 compensators.
Yes—Griffin designed the Gate-Lok as one of the fastest mounting interfaces on the market. It's also wear-resistant and doesn't suffer from the degradation issues common to ratcheting systems, so it stays reliable through repeated attach-detach cycles.
Griffin's mounting tolerances are ground to ten-thousandths of an inch, which keeps point of impact shift minimal and repeatable. This precision manufacturing means you can use the suppressor and remove it without fighting unpredictable zero changes.
The package includes the 30SDK suppressor, a 30SD muzzle brake mount, a shim set for fine-tuning, and a protective silencer pouch.
