VLTOR IS SWITCHING OVER TO FORGINGS FOR THEIR UPPER RECEIVERS. WHILE THEIR BILLET RECEIVERS ARE STIFFER THAN A CONVENTIONAL FORGED RECEIVER, THEIR NEW FORGED MUR IS STIFFER YET, BASED ON TESTING THEY'VE DONE. INTERESTINGLY, EVEN THOUGH THE FORGED AND THE BILLET RECEIVER ARE DIMENSIONALLY IDENTICAL, THE FORGED RECEIVER WEIGHS 0.4 OUNCES MORE.
IT'S NOT EASY TO TELL THE DIFFERENCE BETWEEN THE TWO, VISUALLY. THE FORGED RECEIVER LOOKS LIKE IT HAS WHAT A CUSTOM 1911 BUILDER WOULD CALL A LIGHT "CARRY MELT" ON THE CONTOURS ON EITHER SIDE. THE FORGED RECEIVER IS THE TOP ONE: ![]() FORGED: ![]() BILLET: ![]() MY FIRST BUILD WITH THE FORGED MUR: ![]() ![]() ![]() SO, NOW WE HAVE A STIFFER RECEIVER, YET STILL STRAIGHT AND TRUE. LIFE IS GOOD! THANKS TO SMG LEE FOR THE PIX! GOOD SHOOTING, WES GRANT MSTN.BIZ |

Wes, is that a PRI QC brake on that rifle, and if so, is it installed upside down?
|
|
So, is this going to be cheaper? If not, then I don't see what the purpose is, considering the billett is lighter.

Im glad there is a forged option |
|
|
what is the purpose of the two piece brass deflector? It is pinned on, yes?
|

SAME PRICE, $229.95 AS SHOWN WITH SHELL DEFLECTOR, AND $199.95 WITH SHELL DEFLECTOR ONLY. |

YOU GUYS DON'T MISS A THING! YES, THAT'S AN MSTN QC BRAKE, HAND TIGHTENED JUST FOR THE PIC. WES |

FROM THE INITIAL POST: "WHILE THEIR BILLET RECEIVERS ARE STIFFER THAN A CONVENTIONAL FORGED RECEIVER, THEIR NEW FORGED MUR IS STIFFER YET ..." THIS IS A GOOD THING. |
|

AS YOU MIGHT ASSUME, TO DEFLECT BRASS AND PROVIDE A HOUSING FOR THE FORWARD ASSIST, PLUS A CONSPICUOUS FLAT SPOT FOR A LOGO. YES, IT IS PINNED ON. |

right...but, why two piece when every other upper is one piece? |

Wes,
I have a billet MUR, and I think it is perfect in every way. I just wanted to know would anyone notice any great advantage between the forged, and billet. Is the added stiffness really even going to be noticeable? |
|

modularity. so you can give the consumer a choice of shell deflector only, or shell deflector and forward assist without two different forgings. |
|
|
This is going to sound petty, but I think the billet looks MUCH better.
|
|
Forged?
Because it's stronger than "billet"? What a novel idea! From a damn SMART company. "the billet looks better" everything that's currently wrong with the industry, AR specifically. |
|
looks awesome! it lacks the sharpness in the edges but they seem to have changed that in the machining.
|
|
The difference in strength between a forged and billet receiver is very, very small. You will never notice.

I KNOW OF TWO HIGH END BILLET RECEIVERS STRONGER/STIFFER THAN ANY CONVENTIONAL FORGED FLAT TOP UPPER RECEIVERS. ONCE A CERTAIN THRESHOLD OF STIFFNESS IS ACHIEVED, DIMENSIONAL ACCURACY BECOMES PARAMOUNT. YET MORE RIGIDITY IS NEVER A BAD THING. GOOD SHOOTING, WES |

has there been testing done on this receiver stiffness? I would like to see that for sure. "The difference in strength between a forged and billet receiver is very, very small. You will never notice. " maybe so but should I pay more for something that by it's nature is weaker? Why not go back to using castings? There's plenty of cast receivers still out there. if a forging is machined and a "billet upper" is machined there's no difference between the two as fas as accuracy potential goes. Put the rail in the right place, machine the receiver face square; I know what AMU uses. Regardless, Vltor did this for a reason and I don't think it was marketing. It makes damn good sense to me, a whole lot more sense than this "billet" craze has made. But what do I know, mmmv (my mileage must vary). Good job, once again, VLTOR! You've got everybody beat in my opinion from rails to stocks and now receivers. I wish they would make some optic mounts. ![]() |

It's from the forging. |
|

I guess I'm down to two questions:
1) Would you consider the newer MUR a product improved version of the MUR, or an added option? 2) Will they still offer the billet upper in the old configurations/appearance? The slight alterations in the cam region, and more bulbous section below that on the port side of the upper is the only thing that would lead me to beleive that added R&D/product development has gone into this version. All they'd need to add are T markings on the top, and I'd shell out for another rifle to have both iderations of the MUR - I love my current one, but if I felt the need to make an SDMR profiled upper, this would be THE choice. |

1. THE FORGED MUR WILL REPLACE THE BILLET VERSION. VLTOR FEELS THE INCREASED STIFFNESS OF THE FORGED VERSION MAKES IT A PRODUCT IMPROVEMENT OVER THE ORIGINAL VERSION. 2. AS FAR AS I KNOW, THE ANSWER IS NO. GOOD SHOOTING, WES |
|
|
That's nice. I just bought a billet one. Sorta like when I bought an Ipod Mini because it was on sale and then a week later new smaller, color-screen versions are the same price.
I didn't buy it for the billet, but just because I wanted a flattop upper w/o forward assist but with shell deflector. |

NEW - FROM THE VLTOR WEBSITE:
Since its introduction, the MUR has constantly undergone testing and evaluation in an effort to ensure that we are offering the finest upper receiver possible. One of the most significant changes the MUR has seen was the manufacturing change to using forgings; the MUR is made from a 7075, aircraft grade aluminum forging -- prior to machining, the forging is fully stressed relieved, heat treated, aged twice and undergoes a proprietary cryogenic treatment. Throughout the industry, it has been accepted that a part made from a forging has the potential to be stronger and more stable than parts made even from machined "billet" parts. The forging process is expensive; it involves the manufacture of forging dies and the machinery needed for the actual forging process – the result is a part that has a denser and more uniform grain structure. The MUR is precision machined and each part is finished and fit by hand, we control the material selection and oversee the forging and heat treatment processes, each step of the machining process is watched meticulously and every finished MUR is check for fit – this is the finest upper receiver made. The MUR comes in two models: one with a Bolt-Assist/Shell-Deflector (MUR-1A) and the second with a Shell-Deflector only (MUR-1S). Being a modular design, Vltor offers the service of exchanging the Bolt-Assist assembly for a Shell-Deflector only assembly and vise-versa. |

Either way, I think they make a hell of a product. If I where to do another precision build, I'd get the forged with out thinking twice. That being said, I'm still very happy with the billet VLTOR receiver that I'm currently shooting with.

I'M OUT. MORE ON ORDER, OF COURSE. EVERYONE HAVE A GREAT 4TH, WES |
|
|
The higher weight SUGGESTS a higher density of the metal which COULD also explain the greater stiffness. |

NIGHTFORCE 2.5-10X24 NXS IN THE FIRST PIX. NIGHTFORCE 1-4 NXS IN THE LAST PIX. LARUE SPR MOUNT IN BOTH CASES. GOOD SHOOTING, WES |
|
|
Is the VIS going to still have a billet upper on it. I like the billets sharper lines. If the VIS is going to forged uppers, that would change my preference on my next rifle.
|
|
VIS going forged too, rainier arms has a bunch of billet ones in stock, hurry and buy them so I can get the forged ones.
|

How long till Mark Larue switches to forged Stealth recievers
|

HOW LONG IS FOREVER? I DON'T THINK IT WILL HAPPEN. GOOD SHOOTING, WES |
|
|
Forever is a very long time; if the universe oscillates from Big Bang to Big crunch it is pretty much irrelevant anyway.
***** Anyway: any problem using a Young NM chromed BCG in the forged Vltor upper? I saw in a previous thread you said the Young was "beefier"; I am worried sick that the tolerances might be too close with two high-end products interfacing, in case the orcs attack. |

WHILE TOLERANCES DO STACK UP SOMETIMES, I'M RUNNING ONE MYSELF WITH NO PROBLEMS. I HAVE EVEN ADDED 3 MICRONS TO THE OUTSIDE RADIUS OF THE BOLT CARRIER BY DIAMONDBLACK COATING IT. GOOD SHOOTING, WES |
|
|
just picked up 3 for myself. Fantastic product well out in front of the high end, other than standard issue, upper receiver race.
|
|
Wes, why doesn't someone try and talk VLTOR into doing some that are slicksides. That would be nice.
|
|

Where'd you get them? No one seems to have them in stock. You took too many for yourself. |
|

+1 They used to do one w/out the F/A...Do they not anymore? |
|
|
THEY STILL OFFER ONE WITHOUT FORWARD ASSIST. IT STILL HAS A BRASS DEFLECTOR, THOUGH.
GOOD SHOOTING, WES |
|
while I have to say I think the billet looks better... the forged ones look like they will match a regular lower better.
question, what holds the forwards assist/ shell deflector in place other than a 1/16th roll pin? |
