VLTOR MUR with no forward assist.                                 
The Modular Upper Receiver (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 stronger platform. This more rigid upper receiver will increase accuracy and reliability, while extending the life of the interfacing components, such as the bolt carrier group and barrel assembly. he Modular Upper Receiver (MUR) is a rigid MilSpec flat-top upper receiver made to fit all AR15/M16/M4 rifles and carbines.
