Bushmaster rifles have quickly become the choice of AR-15 buyers due to their accuracy, reliability, and value. The heavy barrel, with chrome-lined bore and chamber, offers exceptional accuracy for its length and is externally manganese phosphate-finished for complete protection against corrosion and rust. Forged, lightweight 7075T6 aircraft quality aluminum receivers have all M16-A2 design improvements including cartridge case deflector, last round bolt hold-open, and raised ridges for magazine release button protection. This combo includes a 16-1/2" standard with a 1 in 9" twist and a 24" fluted barrel and upper assembly. The rifle features a fixed stock, a post front sight, and an adjustable rear sight, and comes with two 10-round magazines and two 15-round magazines. Its stock, metal, and bore are all in good condition.
