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.
Due to our Lifetime Warranty, we advise that you not remove or attempt to remove your shell deflector. The shell deflector is pinned in place during factory assembly. Our Lifetime Warranty covers all of our products as long as they are not modified in any way (i.e. disassembly). We do offer a service in house that will maintain your Lifetime Warranty. Please contact us for more information.

1. What kind of mounting block should I use?
We recommend that you use the Geissele Reaction Rod for installation. Damage could incur if you use clamp style mounting blocks or blocks that do not support the upper internally. This could void your warranty.
2. How do you remove the forward assist to install a custom dust cover?
Due to our Lifetime Warranty, we advise that you not remove or attempt to remove your forward assist. Our Lifetime Warranty covers all of our products as long as they are not modified in any way (i.e. disassembly). We do offer a service in house that will maintain your Lifetime Warranty. Please contact us to arrange this service.

We use KG Industries GunKote FDE on these uppers.
Tan GunKote 2404F
Foliage Green GunKote 2416F
I just purchased this “MUR” upper receiver and I am very impressed with the attention to detail in its manufacturing. The fit on my “Colt” lower is perfect and the finish is flawless. This will be used in fitting up an upper with a “Wilson Combat” match grade barrel. From my initial impression, I expect to get great groups from my rifle when it is complete. Thanks for providing such a fine upper receiver.
I have 2 MUR uppers and they both fit very tight on my duty rifle(Colt) and both of my person Sig M400 and Sig 516. Zero slop and very minimal gap between receivers. A little pricey, but very well worth it. Awesome stuff, very well built and engineered.
I built my AR so I would fully understand these guns. A friend recommended that I use the MUR upper receiver, It fits very snug with no slop at all and is very well made. Another buddy bought a very well known expensive AR and it is lose between the upper and lower to the point that this relative newb wasn’t impressed at all. I would recommend this upper to anyone that asks, in fact I will be getting another for my next build.
Great product! Perfect fit and finish and 100% reliability. I have this receiver with mated with a BCM 16″ SS410 1/8 twist barrel and lower with a DD bcg. The MUR is a great piece for my system. It allows me to consistently shoot 3/4″, 5 shot groups at 100yds with match ammo.
Just received my 3rd MUR for a MK12 build. It fits tight to all 4 of my lowers and the barrel fits snug as well. VLTOR is great quality stuff.
