CMMG unveiled its innovative MkW ANVIL platform n .458 SOCOM less than a year ago, and now the manufacture has announced it is available in three new models chambered in 6.5 Grendel.  

"We strive to deliver rifles that are optimized to run efficiently for the long haul,” said CMMG CEO Chris Reinkemeyer. “Our engineers are creating unique rifles that are specifically designed to harness calibers that are known to be problematic when used in an AR15 platform." 

                           

Reinkemeyer continued, "We're extremely excited to roll out the MkW ANVIL in 6.5 Grendel, which we have found to be a very flat-shooting round capable of impressive long-range accuracy and lethality on medium to large-sized game."

CMMG's MkW ANVIL is a mid-sized AR rifle platform that is uniquely engineered to easily handle calibers with large casing diameters and significantly high bolt thrust. The most defining feature of the MkW ANVIL is CMMG's unique Powerbolt design, which allows the rifle to utilize a modified AR10-sized bolt for increased durability. This is important because large-diameter cartridges such as 6.5 Grendel would require material to be milled out of a standard AR15-sized bolt in order to function, resulting in a thin, fragile bolt face. The Powerbolt design allows the MkW ANVIL to take 6.5 Grendel, and many others, to their full potential.

The MkW ANVIL is built on an AR10-sized frame with the upper receiver shortened by three quarters of an inch to minimize weight and increase ergonomics. Although the frame is based on the AR10 platform, the magwell on the lower receiver has been uniquely designed to accept standard AR15 magazines. This allows the rifle to utilize the durable AR10-sized bolt with calibers such as 6.5 Grendel, which have a case diameter that is larger than a 5.56 NATO. The result is a mid-sized AR that delivers superior durability while minimizing weight.

Each MkW ANVIL in 6.5 Grendel ships with one 10-round magazine. The barrel is a medium taper 416SS SBN with a 1:8 Twist and threaded 5/8-24.  For those who already own a CMMG MkW ANVIL in .458 SOCOM, CMMG will also offer 6.5 Grendel upper receiver groups that will be compatible with any MkW ANVIL lower.
