The CMMG Zeroed 556K suppressor is a compact, direct-thread sound moderator purpose-built for 5.56mm rifles and other small-caliber centerfire platforms. If you run a modern tactical rifle, AR-15, or other 5.56 shooter and want genuine hearing protection without the bulk, the Zeroed 556K delivers serious suppression in a package that won't bloat your sight picture or overload your handguard. CMMG manufactures this suppressor entirely in-house, which means no compromise on materials, tolerances, or fit—just a well-made can at a straightforward price.
Built from heat-treated 17-4 stainless steel and finished with a surface-hardening nitride coating, the Zeroed 556K resists fouling and corrosion even during extended shooting sessions or in harsh field conditions. The tubeless laser-welded baffle design keeps weight down to just 11 ounces (without mount), so you're not hanging a pound of steel on the muzzle. At 5.2 inches long (without the direct-thread mount), it's genuinely compact—ideal for close-quarters hunting, shorter-barreled builds, or anywhere a slender profile matters. Full-auto rated construction means it'll handle sustained fire when you need it, though expect a brief cooldown after roughly 240 rounds of continuous shooting.
The Zeroed 556K ships with two direct-thread HUB mounts—1/2"-28 and 5/8"-24—so you can match your rifle's existing thread pitch right out of the box. Both mounts feature 7/8-inch wrench flats, and the suppressor's front cap has a 3/8 square drive, letting you swap or remove the can with basic hand tools. Since all Zeroed centerfire cans accept HUB mounts, you can also upgrade to a quick-detach system later if your needs change. Cleaning is straightforward: the tubeless design and nitride finish handle ultrasonic cleaners or most common solvents without worry, so you're not stuck with proprietary solutions or special procedures.
Before ordering, verify your rifle's thread pitch and confirm the included mounts match your barrel—if your gun requires a different threading, you'll need to source that mount separately. For hunters, precision shooters, and tacticalists who want genuine hearing protection and a refined shooting experience, the Zeroed 556K is a logical, no-nonsense choice.

The suppressor includes two direct-thread HUB mounts: one 1/2"-28 and one 5/8"-24. Check your rifle's muzzle thread pitch before ordering to ensure one of these mounts is compatible. If your barrel uses a different pitch, you'll need to purchase the correct mount separately.
Yes, but barrel length depends on caliber. For 5.56mm, the minimum barrel length is 10.5 inches. If you're running a 5.7x28mm or 4.6x30mm platform, the minimum is 5 inches. Always verify your specific rifle's requirements before mounting.
The suppressor itself is direct-thread only, but it features a HUB mount-compatible interface (1.375"-24). You can purchase a separate quick-detach HUB mount and muzzle device in the future if you want to upgrade to QD functionality.
The tubeless, laser-welded design and nitride finish make cleaning straightforward. You can safely use ultrasonic cleaners or nearly any common solvent without worry. Disassembly and reassembly require only basic hand tools—the 7/8-inch wrench flats on the mount and 3/8 square drive on the suppressor cap handle removal easily.
