With increased rigidity, this upper brings hard-use to a new level.
The VLTOR MUR is a rigid Mil-Spec upper made to fit all AR15/M16 M4 rifles and carbines. The MUR was developed to give the customer a Mil-Spec correct upper receiver with a thicker wall, making the MUR upper receiver a stronger platform. This more rigid upper receiver will increase accuracy and reliability, while extending the life of the interfacing components. These upper receivers come pre-assembled, and will have a dust cover, and forward assist installed.
