MUR-1A: Modular Upper Receiver-NULL (GRADE-B)

VLTOR MUR-1A Forged Upper Receiver (Grade B)

These MUR-1A receivers feature an undyed Type 3 hardcoat anodizing in a new colorway we call “Null”. The color and undertones vary greatly from part to part. There is inherent color variation between the receiver body and deflector module due to their differing alloys. The “Null” color changes in different lighting conditions. The photos on this page showcase examples in different lighting conditions. Some of the photos include a black receiver for visual reference.

The MUR-1A is a rigid Mil-Spec flat-top 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.
