5.56mm is one of the most ubiquitous calibers in the USA, so why not have a dedicated suppressor for your 5.56mm firearm? Made to deliver maximum sound suppression on .22 caliber centerfire cartridges, the ZEROD 556K keeps things light and tight with its compact "K" size footprint and direct thread mounts and an overall length of just 5.5".
Although reasonable in price the ZEROED 556K makes no compromises in quality. Full 17-4 stainless construction and a nitride finish means this suppressor resists fouling and corrosion like no other. For easy disassembly, the included direct thread mounts feature 7/8 wrench flats and the suppressor features a 3/8 square drive in the end cap. Have a unique thread pitch on your firearm or prefer to use a QD mounting system? The ZEROED 556K is 1.375"-24 HUB compatible, accepting the most common suppressor mounting systems.
All ZEROED suppressors are made 100% in house by CMMG in our facility, allowing for maximum quality control and affordability.
