The Battle Arms Development Authority Elite Rifle was designed with the next generation AR-15 in mind. This AR-15 rifle is built around the 7075-T6 billet lower receiver with integral ambidextrous controls and a matching billet upper receiver. It also features the 15" free float M-LOK handguard that is lightweight and gives plenty of room for customization. The 16" barrel is chambered in 5.56 NATO with a 1:7 twist rate. The barrel is machined from 4150 chrome moly steel and black Nitride finished for corrosion resistance and accuracy. Each barrel is individually head-spaced to the Carpenter 158 bolt. Combined with the 8620 steel carrier and black Nitride finish, this rifle is extremely reliable and smooth shooting.Features: 16" 5.56 NATO 7075-T6 billet receiver set Battle Arms Gray finish Integral ambidextrous controls Enhanced Nickel Teflon trigger Rack ambidextrous charging handle BAD-ASS-PRO ambi safety selector Extended magazine release 3-position adjustable pistol grip B5 Bravo stock
