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. The ORC has a six-position telestock that reduces overall length by 4" when fully collapsed. The receiver-length Picatinny optics rail makes optics mounting easy and the A2 birdcage-type flash hider to control muzzle flash. This rifle features a 1x30mm red dot sight, a 1 in 9" twist, and a 30-round magazine and comes with the original factory box. Its stock, metal, and bore are all in very good condition.
