The Diamondback DB1717K004 DB15 is a no-nonsense AR-15 platform semi-auto rifle chambered in 5.56x45mm NATO/ .223 Rem, built around Diamondback's DB15 series for dependable range, duty, and training applications; its 16-inch Diamondback 4150 CrMoV medium contour barrel with a 1:8 RH twist and black nitride finish provides consistent accuracy and long service life while the carbine-length gas system and a shot-peened, MPI-inspected mil-spec 8620 carrier BCG ensure reliable cycling under extended use. The forged 7075 T6 A3 flattop upper and forged 7075 T6 lower give a rock-solid receiver platform that is optic ready, supported by a standard 2-piece black plastic handguard, A2-style black grip, and a 6-position ATI mil-spec buttstock for versatile ergonomics and cheek weld. With an A2 flash hider threaded 5/8 x 24, manual thumb safety, standard trigger, and a weight around 6.25—6.65 lb, this semi-auto rifle balances controllability and portability for range sessions, training drills, and patrol duty; note that this firearm requires FFL transfer and is configured for right-handed shooters.
