The Vltor Modular Upper Receiver or MUR is forged out of 7075 aircraft grade aluminum that has been stress relieved, heat treated, and then cryogenically treated. This, along with the thicker walls of the receiver, makes the MUR stronger and more rigid than a standard billet flat-top upper, and with the forward assist deleted it weighs in at only 8 ounces. Including the forward assist it weighs slightly more at 10 ounces. The greater strength and rigidity of the MUR gives the shooter a more accurate and reliable platform while reducing wear and tear on the bolt carrier. Available with or without a forward assist.
