The MUR is a rigid MilSpec flat-top upper receiver made to fit all AR15/M16/M4 rifles and carbines.

The MUR was developed to give the customer a MilSpec correct upper receiver with a thicker wall making the MUR upper receiver a more rigid platform. A more rigid upper receiver will increase accuracy and reliability while extending the life of interfacing components such as the bolt carrier group and barrel assembly.
