VLTOR MUR Upper Receiver with Forward Assist

The MUR 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. The MUR-1A model comes equipped with a shell deflector and forward assist. The MUR-1S comes with a one-piece machined shell deflector only.

    Receiver itself slaps pretty hard. Fit, finish, forward assist that isn’t located up your left nut.
    That being said I was really bummed to see it have a polymer ejection port cover. I know not a huge thing but damnit I want it all to be metal, and I also didn’t see it in the description or if its there I didn’t see it readily available.

    Have used multiple Vltor MUR uppers, one of the best uppers on the market. Do the orders with Rooftop Defense because of the best customer service and shipping times.

    Great upper – well-built with extra material where needed to improve rigidity. Love these VLTOR uppers – quality part – you get what you pay for!

    I used this to build a gen2 Noveske clone with a BCM QRF 12, and a surefire SOCOM CTN FH, all purchased here. Everything looks great, I can’t wait to get out to the range.

    Everyone knows Vltor Mur is the best , I was not disappointed. Rooftop got this too me fast, I wasn’t expecting it for several more days and boom it showed up. Right item, right time , right price , just Rooftop being Rooftop, top notch! Building your dream rifle takes a lot of your disposable income, I sat down and just gazed upon my new Vltor while enjoying my Top Ramen. Thanks Rooftop!
