Barnes Bullets, already no stranger to alternative-material projectiles, has announced a new line of lead-free ammunition designed specifically to function through the AR-15 platform (see Barnes' RangeAR video below). The RangeAR line features copper-jacketed, zinc-core, open-tip, flat-base bullets that offer sufficient density, but in a package lighter than comparable lead ammunition. Range AR will initially be offered in two loads—a 52-gr. 5.56x45 mm NATO offering and a 90-gr. .300 Blackout option. Barnes’ use of zinc for the RangeAR line has allowed the company to utilize light-for-caliber bullet weights, which in turn affords its engineers the opportunity to maximize the velocity potential of these chamberings. The 5.56x45 mm NATO load clocks in at 3200 fps from a 20” barrel, while the .300 Blackout load reaches 2550 fps out of a 16” barrel. Despite the light bullet weights, however, Barnes has carefully designed RangeAR to function well in rifles with higher twist rates. Barnes has also carefully selected specialized propellants optimized for use in ARs, offering superior performance through rifles of any barrel length. Intended for target, training and competitive use, Barnes RangeAR Ammunition delivers high velocities and flat trajectories, while still being more economical than many lead-free bullet options. Price (per box of 20): $19 in 5.56x45 mm NATO, $21.50 in .300 Blackout. Contact: Barnes Bullets, LLC., 38 N. Frontage Road, Mona, UT 84645; (435) 856-1000; barnesbullets.com.
