The Griffin Armament M4SDK 5.56mm rifle silencer is the shorter and lighter version of its brother, the M4SD-II unit. Engineered for suppressor enthusiasts who prefer minimal length and weight add-ons when utilizing a can—while maintaining effective sound reduction not afforded by novelty miniature suppressors popular to the market—the M4SDK is a great addition to any collection.

Calling Wisconsin home, Griffin Armament is one impressive outfit. This team has a wide assortment of suppressors under their belt, with no slowing down in sight. Founded by two military brothers intent on preserving the hearing of fellow shooters, this manufacturer entrusts their experience to craft high-quality, affordable cans. Add the M4SDK model to the list.

Further Intel

The Griffin Armament M4SDK provides a high level of sound reduction (31 dB) while sustaining the extreme durability of the aforementioned flagship M4SD-II silencer. Moreover, it is A2 rifle compatible, so versatility is not lacking. Designed with durable stainless steel, the M4SDK is tough enough to attain the full-auto rated designation. Measuring a scant 5.75” and weighing a mere 14.5 ounces, this model is as maneuverable a 5.56mm rifle unit as you will find. To that end, this innovative mini-suppressor surpasses competing same-category options by a broad margin, offering market-leading performance and value in its class. Although miniature in stature, not owning one is a major malfunction.
