New ARs: Rock River Arms X-Series
By The Editors
Rock River Arms' big introduction for 2014 is the X-Series of AR rifles. The guns come in a black tactical version or a desert tan hunter version. The tactical version sports a muzzle break with a nasty set of teeth. The series offers four calibers: .223, .308, 6.8mm SPC, and .458 SOCOM.
