A couple years back, CMMG surprised the shooting community by launching its Mutant, a nifty little gas-impingement operated semi-automatic AR pattern rifle that was built around the 7.62x39 mm cartridge—which, as you probably know, is far more commonly associated with the AK-47. The Mutant got rave reviews from media members and consumers alike—even winning a Golden Bullseye Award from our sister publication, American Rifleman—which inspired the company to keep toying with the idea. The result is the rifle that became our latest episode of #SundayGunday, and is chambered in, of all things, .458 SOCOM: Meet the CMMG MkW Anvil. You can learn more about it in the video embedded above.

Hardware Review: Browning BAR MK 4 Hunter

First, the Browning Automatic Rifle addressed in this article is not the renowned 1918 BAR of military fame. I’ve actually seen an American Rifleman editor hunt hogs with a reproduction 1918 BAR. While it was a spectacle to behold, it’s probably not the optimal choice for the deer woods, but hey, who am I to judge? The Browning BAR we’re talking about in this article is the iconic hunting rifle.
