Rock River Arms teamed up with renowned hunter Fred Eichler to produce Eichler's vision of the ideal predator-hunting rifle. The result of their collaboration was the new Rock River Arms Fred Eichler Series Predator2 AR-15 rifle.
The new Rock River Arms Predator2 rifle is constructed with forged-aluminum receivers, providing users with an A4-style flattop upper receiver that features an integrated Picatinny rail for mounting optics. The rifle ships with a high-rise optics mount designed for use with 30 mm riflescope tubes, ready for mounting with the user's optic of choice.
The receiver is matched up with a stainless-steel barrel that features a 1:8-inch twist rate designed for use with a range of hunting ammunition on the market. The barrel features a .223 Wylde chamber, which allows the rifle to fire both 5.56 NATO and .223 Rem. ammunition while still being able to gain the accuracy potential from match-grade .223 Rem. options.
The barrel is cryogenically treated and features a bead-blasted finish. At the muzzle end of the barrel, users will find an exclusive Fred Eichler Series muzzle brake, designed specifically to decrease recoil and dampen muzzle flash. Each rifle shipped by Rock River Arms comes with a 3/4 MOA guarantee at 100 yards.
The Rock River Arms Predator2 AR-15 is equipped with a low-profile gas block and is covered with a free-float Fred Eichler Series extended handguard. The fore-end features a full-length Picatinny rail that allows for added flexibility in mounting optics and other accessories. The handguard also provides a 2.5-inch Picatinny rail at the 6 o'clock position.
Inside the receiver, shooters and hunters will find a Rock River Arms two-stage Varmint Trigger, ensuring that users have the best possible trigger pull in order to make accurate shots on small, fast predators. The trigger also allows for use in competition scenarios, thanks to the crisp, lightweight pull that measures 3.5-4 pounds.
Other furniture features on the Predator2 AR-15 include the company's Operator CAR buttstock and a Hogue Overmolded Rubber pistol grip. Guns shipped to states with feature-based laws on AR-style rifles will be equipped with the company's Operator A2 stock. The rifle is also equipped with a Bravo Company BCM Gunfighter medium-latch charging handle for easy, one-handed operation.
Finally, the entire rifle is coated with Rock River Arms' ROCKote ghost camouflage finish, which aims to protect all rifle components from corrosion, wear and damage in harsh hunting environments while providing an attractive look to the gun.
The suggested retail price on the Rock River Arms Fred Eichler Series Predator2 AR-15 rifle is $2,225.
