Product Summary

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 7075T6 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.

The Bushmaster Model M4A3 11.5/5.5" Carbine features a six-position telescoping buttstock and is fitted to an A3 configuration. The standard A2 sight is adjustable for 1 M.O.A. elevation and 1/2 M.O.A. windage. The 11.5-inch heavy barrel and 5.5-inch flash suppressor combine to create a 16" legal length barrel.
