Rock River Arms is introducing a new AR-15 pattern varmint hunting rifle called  the Rock River Arms All-Terrain Hunter (ATH). This new AR-15 is built around a heavy cryogenically treated 18-inch stainless steel barrel with a 1:8-inch twist. It has a .223 Wylde match chamber that is guaranteed by Rock River Arms to shoot ¾-MOA groups . The .223 Wylde chamber configuration is optimized for maximum accuracy in .223-caliber rifles with a shorter chamber throat and also by slightly changing the geometry of the chamber itself. These chambers can handle either types of ammunition, no matter if it is 5.56 NATO or commercial .223 Remington.

The Rock River Arms All-Terrain Hunter is designed with a full size 13-inch extended, lightweight, free-floating rail system that provides ample space for hunters to attach all sorts of hunting accessories, especially for low light varmint hunting conditions. The rail’s topmost surface has a full section of Picatinny rail, while the sides and bottom are designed to be M-Lok compatible. Topping off the features of this rifle is Rock River Arm’s factory two-Stage Varmint trigger that has a 3.5 to 4 pound trigger break.
