USED Diamondback Tactical DB15 rifle in 5.56x45. Barrel length is 18in with muzzle. Does not include magazine. It appears the previous owner installed an improved muzzle device on the weapon, the charging handle has an extended latch, and the stock was upgraded with extend cheek pieces. Bore looks clean and sharp, bolt carrier group doesn't show much wear. This rifle does not appear to have been fired very often.
