Designed specifically with the modern hunter in mind, the ATH rifle's precision 18-inch heavy-match stainless steel barrel is cryogenically treated for maximum stability and accuracy even under high-volume shooting conditions. Chambered in .223 Wylde to accommodate both 5.56 NATO and .223 Remington, the ATH barrel incorporates a 1:8-inch twist rate that boasts a guaranteed 3/4 MOA accuracy at 100 yards.
The barrel mates to a forged A4 upper receiver and is shrouded by a 13-inch extended lightweight free-float handguard. The co-witnessed, full-length rail system offers plenty of room for high-magnification optics and thermal gear for late-night varmint hunting, while the M-Lok compatible handguard ensures ample mounting positions for bipods, slings, and lights.
Hunter ergonomics also score high marks with the RRA ATH. A winter trigger guard provides room for the trigger finger even when wearing heavy gloves. The Hogue pistol grip also accommodates gloved hands with its no-slip rubber coating and prominent finger grooves. To meet changing shooting scenarios and clothing requirements, a six-position RRA Operator CAR buttstock rounds out the lower receiver assembly. With its generous cheek weld and textured buttplate, this stock makes it easy to maintain a secure and comfortable sight picture in a fast-paced hunting environment. The stock also incorporates multiple quick-detach sling mounting points and a watertight battery storage compartment.
Operational controls continue this ergonomic theme. The unique star safety selector, is designed for gloved manipulation. More noteworthy, however, is the inclusion of RRA's world-class Two-Stage Ultra Match Varmint Trigger. With a light take-up, crisp break and 3.5-4-pound pull weight, the trigger is intended to minimize shooter-induced shot disturbance—a critical factor in long-range accuracy.
Additional features of the All-Terrain Hunter include RRA's Operator muzzle brake, owner manual, plastic hard case, and one 20-round steel magazine.
