Description
The CMMG Mk57 GUARD is a new AR15 chambered in 5.7X28mm. The Mk57 is fed from FN FiveSeven style magazines and uses CMMG’s patent pending Radial Delayed Blowback operating system that easily handles the 5.7X28mm cartridge while simultaneously keeping weight and felt recoil to a minimum. It also features a new patented dual-pinned fully machined bolt catch linkage making operation both easy and intuitive. The Mk57 is threaded 1/2-28 to accept the most common 5.7 rated suppressors and is the perfect carbine for defending your home or enjoying a day at the range. Action: Semi-Auto
