Description
The MUR-1A is a rigid Mil-Spec flat-top upper receiver that fits all AR-15/M16/M4 rifles and carbines. The MUR was developed to provide the customer with a Mil-Spec-compliant upper receiver with thicker walls, 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.
