Rock River Arms BT3 Predator

Rock River Arms has just introduced their new RRA BT3 Predator HP 6.5 Creedmoor rifle, an AR-308 pattern precision-oriented rifle with a free-float 24-inch barrel, built on a machined billet aluminum upper and lower receiver set. This set was designed to be sleek and ergonomic and to increase the rifle’ performance beyond what is available when using standard forged lower or upper receivers. The Rock River Arms BT3 Predator HP takes advantage of the 6.5 Creedmoor’s ballistics to provide precision rifle shooters with an accurate and easy-to-shoot rifle system for shooters in search of an AR-pattern rifle that’s capable of making the long range shot, be it at the range or in the field. Besides including a Rock River Arms 2-stage, match-grade trigger, the BT3 Predator HP employs a cryogenically treated 24-inch barrel with a 1:8-inch rifling twist and a six-position stock for an improved cheek weld, this rifle has what it takes to take full advantage of the velocities and stability that’s built into 6.5 mm projectiles.
