In a recent range day on Greyhive, Black Rifle Medic ran the can across 300 Blackout subs, 5.56 supersonic, and 7mm rounds to see how the short .30-cal format actually performs. This isn't a benchtop review. Black Rifle Medic took the ZEROED 30K through a working range session — 220 grain MagTech subsonic 300 Blackout, 190 grain Sub-X 7mm, 55 grain Yoki 5.56 out of a 12.5-inch AR, and additional rounds through an 11.5-inch upper. The honest takeaway: a K-can is never going to be a full-length suppressor, but the 30K \"takes the edge off\" and runs clean across host platforms. If you're cross-shopping short .30-cal cans for a do-everything host or you want one suppressor that lives on multiple uppers, the field data below covers what the ZEROED 30K actually sounds like, what it's built from, and how it mounts. Key Takeaways 17-4 stainless steel construction with nitride coating on the tube exterior and internal baffles. Hub-compatible — accepts ASR, Plan A, Plan B (Griffin), and Bravo-style mounts. K-can format — shorter and lighter than a full-length .30-cal, with a corresponding tradeoff in dB reduction. Black Rifle Medic tested it on 300 …
