CMMG has announced the release of its new MkW Anvil, a mid-sized AR rifle platform chambered in .458 SOCOM. The MkW Anvil is engineered to handle calibers with large casing diameters like, as we just mentioned, .458 SOCOM.

The MkW Anvil utilizes CMMG's Powerbolt design, allowing it to use a modified AR10-sized bolt for increased durability. Large-diameter calibers like .458 SOCOM would require material to be milled out of a standard AR15-sized bolt in order to function, making the Powerbolt a necessity. The rifle is also built on an AR10-sized frame, with the upper receiver shortened by three quarters of an inch to minimize weight and increase ergonomics. That said, the magwell on the lower receiver remains designed to accept standard AR15 magazines. About 10 .458 SOCOM cartridges fit single stack in an AR15 magazine, so CMMG married features of AR10 and AR15 designs in order to create the Anvil.

"Our experiences with .458 SOCOM have been extremely positive in terms of accuracy and lethality on large sized game. With the new MkW ANVIL, we're offering our customers a rifle that's been engineered to maximize the performance of this exciting caliber," said Chris Reinkemeyer, CEO of CMMG.

The MkW ANVIL is built with a carbine-length gas system and utilizes an SLR Rifleworks Sentry 7 adjustable gas block. Each rifle comes standard with one modified Lancer L5 magazine that has been optimized for reliability with the cartridge. Additional magazines can be purchased from the CMMG website.

A full-length Picatinny rail runs atop the MkW ANVIL, making it easy to mount your preferred sights or optics. 

Three configurations will be available at the platform's launch.
