Chambered in .223 WYLDE to accommodate both 5.56mm and .223 Rem. hunting ammunition, the Rock River Arms All-Terrain Hunter (ATH) AR-platform rifle’s precision 18-inch heavy match stainless-steel barrel is cryogenically treated for maximum stability and accuracy. The barrel mates to a forged A4 upper receiver and is shrouded by a 13-inch extended lightweight free-float handguard. Its co-witnessed, full-length rail system offers plenty of room for high-magnification optics and thermal gear while the M-Lok compatible handguard ensures ample mounting positions for bipods, slings and lights. Noteworthy is the inclusion of RRA’s two-stage Ultra Match Varmint trigger, with its light take-up, crisp break and 3.5- to 4-pound pull weight. Additional features include RRA’s Operator muzzle brake, plastic hard case and one 20-round steel magazine. MSRP: $1,425. Contact: www.rockriverarms.com
