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. 

Attaching the ZEROED 556K is simple. The B Dapter HUB Mount is CMMG's Plan B suppressor mounting system, compatible with 1.375"-24 HUB threaded suppressors and Q Plan B or Plan B pattern muzzle devices. B Dapter/Plan B QD attachment system allows for a simple, lightweight, and secure suppressor mount. The inner taper seal prevents carbon fouling on the mount and muzzle device threads and securely mates the two together, requiring more force to remove than it does to install, this ensures your suppressor won't back off of the muzzle device as well. 

All ZEROED suppressors are made 100% in house by CMMG in our facility, allowing for maximum quality control and affordability. Lifetime Quality Guarantee We aim to please, that's why every CMMG product is backed by our Lifetime Quality Guarantee against material and workmanship defects.
