Diamondback DB15 Features The Diamondback DB15 is chambered in 7.62x39mm giving this AR platform pistol significantly more downrange energy than typical pistol caliber carbine chamberings while retaining a compact 23 inch overall length. A 7 inch heavy profile barrel machined from 4150 chrome moly vanadium steel with a black nitride finish and a 1:9.5 twist rate is paired with a pistol length gas system tuned for reliable cycling in a short barrel configuration. The bolt carrier group is shot peened and magnetic particle inspected to mil spec standards ensuring consistent reliable function shot after shot. An A2 flash hider threaded at 5/8x24 caps the muzzle controlling flash signature from the short barrel. The upper receiver is a forged 7075 T-6 aluminum A3 flattop giving the DB15 a standard Picatinny rail for mounting optics or sights while the Diamondback carbon lower reduces weight without compromising structural strength. A 6 inch M-LOK handguard provides a mounting surface for lights grips or other accessories around the short barrel. The Magpul MOE grip and black padded buffer tube give the shooter a comfortable familiar interface for controlling the pistol during rapid fire. Feeding from a 28 round CPD magazine and weighing 5.10 pounds the Diamondback DB15 combines compact size serious caliber and modern AR ergonomics into one package available for sale at GrabAGun.
