AR-15/M16 MODULAR UPPER RECEIVER

100004042

Description
Ratings (12)

Extra Metal For Superb Strength & Rigidity; Mil-Spec Dimensions For Compatibility

The MUR is a flattop upper receiver with thicker walls than a standard upper to provide a more rigid platform for greater stability, better accuracy, longer service life, and improved reliability. Precision machined from a fully heat-treated and cryogenically stress-relieved aluminum forging, before hand finishing to final dimensions. All critical interface points are 100% compatible with mil-spec select-fire AR-15/M16/M4 components and lower receivers, and will fit most commercial semi-auto lowers. A slick, dry-lube coating over the hard-anodized finish further guards against surface wear and helps ensure smooth operation of bolt/carrier and other internal components. Comes with true MIL-STD 1913 Picatinny rail with 13 cross-slots, plus forward assist and ejection port door pre-installed. Gunsmith installation recommended. Includes M4-type feed cuts. Available with or without forward assist.

SPECS: 7075 T6 aluminum, Type III, Class 2 hardcoat anodized, dry lube coating, matte black. .250" dia. pivot/takedown pin holes.

Robust AR Upper (05/06/2017)

I have many VLTOR products, however I like their upper the most. The MUR is one of the best and robust uppers for all your AR-15 needs; the MUR-1s is perfect for pistol caliber builds, as the forward assist is not necessary. I would recommend either upper.

Mine doesn't live up to the hype (13/08/2017)

It's just ok. The finish is mediocre, and the dust cover takes about 25lbs of pressure to close. I can't tell if they missed machining the bevel or the cover latch is out of spec. I bought this to go with a Quarter Circle 10 9mm lower, as it seems to be one of the most common options. I'll probably return this to Brownells, and haven't decided if I'll ask for a replacement or look for another upper with no forward assist.

For anyone searching for pure quality, the Mega Arms receivers, both billet and GI spec forged are far and away superior to everything else. I wish they made a lightweight slick side upper.

Great Upper (25/06/2010)

Fits just like a mil-spec upper and is a great match for any milled lower. Also a perfect match with the milled charging handles that were a partnership with Vltor.

Sweet Upper! (15/07/2010)

This thing looks awesome and it built like a tank. Fits my Rock River lower like a glove and the finish matches beautifully. If you want an upper that makes your rifle stand out from the crowd, this is it. Highly recommended.

Very Nice (06/01/2011)

The finish matched perfect to my Panther Arms Lower. The fit is perfect, tight but not to tight to push the take down pin out with my finger. A little pricy but this paticular gun will be worth it.

Great Upper (12/10/2011)

Really nice upper, well worth the extra cost. Fits perfect on just about any lower and cosmetically, it is very sharp looking. Out of all the uppers that I have used, this is by far my favorite.

You get what you pay for! (11/03/2012)

I have tried uppers from several manufacturers and this one is by far my favorite. It is more expensive than other products but the quality is definitely worth the cost. I used this to complete a 6.5 Grendel piston driven rig on a YHM lower and had absolutely no fitting issues at all. Well built, attractive, and perfect compatibility with the other parts that I chose. I will use more of these for future projects and I would recommend them to anyone without hesitation.

EXCELLENT upper reciever!!! (18/04/2012)

I am using this on an ar build that will be used for recreational and hunting and I am very impressed by the quality of it. Has a nice finish against a spikes tactical lower. Also has the best fit to a lower that I have ever seen.

Very Disappointed (01/06/2012)

Very Very disappointed. I spent a year specifically researching and buying part by part to build my AR-15. I thought, "no problem" the Vltor MUR w/Forward Assist would be great between my LaRue handguard and Spike's Tactical Zombie lower. And a nickel boron bolt carrier would work so smoothly with all these. Well apparently Not.

After finally putting together all the pieces the great day came to go to the range and test everything. After less than 140 rounds of PMC 55grain .223 and Remington 55grain .223 The FORWARD ASSIST LITERALLY FELL OFF. I couldn't believe what had just happened, the Forward Assist is held onto the MUR with one of the smallest pins I've ever seen. And in less than 140 rounds it sherd apart. I'm already looking into replacing this Upper with a different. BE WARNED of the Poor Quality and Flimsy Design of the Vltor MUR.

First Rate (30/08/2014)

I built an AR from the bottom up and used this upper based on the description of materials and processes used and I am very pleased with the final result. I own an Armalite and this went together like it all came from same mfg. I can see and feel the quality throughout

Worth the cost (08/05/2015)

This is a great upper for building a custom rifle. It's super lightweight, great machining, and has a great coating. I haven't assembled the rifle yet so my opinion may change but it looks and feels great. I'll still give it 5 stars but the dust cover did look like is was taken off a worn ar15. the dust cover has scratches and is not coated the same as the receiver. I can live with it but other people may not overlook that parts quality.

Solid, high quality receiver (23/07/2016)

Very solid upper receiver. Exactly what I'd expect from VLTOR. Other high end or billet uppers sometimes have a difficult fit with proprietary barrel nuts and rail systems (I.e., YHM, Daniel Defense). This one fit the Midwest Industries Gen3 MLOK perfectly. Also, better cost than Noveske (which VLTOR makes for them).
