Founded twenty years ago to provide firearm enthusiasts a better quality AR rifle that functions as it should at an affordable cost, Central Missouri Machine Guns, or CMMG as the company is better known, believes in taking the road less traveled. With an unwavering commitment to leading the industry with innovation and proprietary technology, CMMG doesn't worry about competitors. CMMG creates something revolutionary in the industry and remains at the front, watching as the competition attempts to replicate it. This 16.1-inch Medium Taper  Barrel Subassembly chambered for Hornady's 6mm ARC round is a classic example of CMMG's relentless commitment to creating unique products guaranteed to satisfy customers. 

  • Supports Hornady 6mm ARC
  • 16-Inch Length
  • 416 Stainless Steel
  • Nitride Finish

This CMMG medium tapered barrel subassembly is made from 416 stainless steel and comes with CMMG's unique and durable Salt Bath Nitride Finish. The nitride finish process from CMMG also retains all the properties of a traditional chromed-lined barrel without suffering accuracy loss seen by uneven chrome application inside the barrel bore. All barrel sub-assemblies from CMMG, including this 16-inch barrel, are properly headspaced. The CMMG barrel chambered for Hornaday's powerful 6mm ARC ammunition features a 1:7.50 twist rate rifling. The barrel subassembly also comes with a properly installed M4 barrel extension and supports either suppressed or unsuppressed firing, making it an extremely versatile powerhouse addition to your AR15 build. Although the gas block and tube are not included, the barrel subassembly from CMMG supports a rifle-length gas port location and a standard exterior diameter gas journal of 0.0750 inches. When customizing your AR upper receiver group to suit your specific style and preferences, this barrel chambered in Hornady's 6mm ARC is the perfect solution. For any budget builder who wishes to pack some versatility and power in their rifle, this 16-inch barrel with a medium tapered profile is the ideal blend of durability and performance at a great price that only CMMG can provide.
