CMMG Zeroed 556K

Overview

The CMMG ZEROED 556K (Kurz) is a purpose-built suppressor designed for the modern AR-15. Engineered to provide a compact "K-can" footprint without compromising on durability, the 556K is constructed from heat-treated 17-4 stainless steel with a surface-hardening nitride finish. This tubeless, laser-welded design ensures a monolithic structure that is full-auto rated and capable of withstanding high-cadence fire on short-barreled rifles (SBRs) and pistols.Versatility and value are the hallmarks of the ZEROED line. The 556K features the industry-standard 1.375x24 HUB mount threading, allowing users to move beyond the included direct-thread mounts and utilize popular QD systems like KeyMo, ASR, or Rearden. Weighing only 13.5 oz and adding just 5.5 inches to your overall length, it significantly reduces muzzle blast and sound signature while maintaining the balance of your firearm. For shooters looking for duty-grade 5.56 suppression at an entry-level price point, the CMMG ZEROED 556K is a top-tier contender.Technical Specifications:Caliber: 5.56 NATO / .223 Rem (Also 5.7x28, .22 ARC)Material: 17-4 Stainless Steel / Nitride FinishMounting: 1.375x24 HUB (Includes 1/2x28 & 5/8x24 mounts)Length: 5.5" (with mount)Full-Auto Rated: YesExpert Verified PerformanceWe ran the ZEROED 556K through a 270-round torture test to see if it lives up to the hype.
