Fayette, MO (June 15, 2016) – CMMG has announced the release of the MkW ANVIL, an all-new mid-sized AR rifle platform, chambered in .458 SOCOM. The MkW ANVIL is uniquely engineered to easily handle calibers with large casing diameters such as .458 SOCOM.The most defining feature of the new MkW ANVIL is that the rifle utilizes CMMG’s unique POWERBOLT design, which allows the rifle to utilize a modified AR10-sized bolt for increased durability. This is important because a large-diameter caliber such as .458 SOCOM 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 this caliber to its full potential.
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. 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 face with the large case diameter of big bore calibers such as .458 SOCOM, in which approximately 10 cartridges fit single stack in an AR15 magazine.
“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. This allows users to easily adjust the gas metering in click-adjustments to work with varying loads of .458 SOCOM ammunition. 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. CMMG’s RKM15 KeyMod™ hand guard is exceptionally light and ergonomic. It also gives users the freedom to mount a wide array of accessories using the KeyMod slots found in the 3, 6 and 9 o’clock positions. For accessories that are not yet KeyMod compatible, CMMG offers 5-slot accessory rails.
The MkW ANVIL is available in three different configurations: Read more
