Bushmaster rifles have quickly become the choice of AR15 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 7075 T6 aircraft quality aluminum receivers have all M16A2 design improvements including cartridge case deflector, last round bolt hold-open, and raised ridges for magazine release button protection. This rifle features a six-position adjustable stock and a Picatinny top rail. Its stock, metal, and bore are all in very good condition.
