Vulcan? Any pictures?
I wouldn't risk my fingers or eyes for a $90 part. Replace it or send it back. |

I wanted a really light weight ar15. It was attached to a cav arms lower. I'm not sure what company made it. I would replace it, but I don't know which company made it. I know that the majority of firearms companies are really good with costumer service, but some don't back their products as much.
   Here are some pictures of the entire upper. If you can identify it that would be helpfull.

If it is Vulcan, you might not have to much luck with them. You could always give them a call and see what they say.

I just took a look at the vulcan website and it by the looks of the brass deflector it's got to be one of theirs. Everyone kind of said "Is it Vulcan?" which makes me think this isn't all that uncommon, right? Does anyone know how their costumer service is?

I've read a couple of posts about their receivers cracking or barrel threads that looked like they melted. I've never even held one of their products, so I can't help you on wether or not they will help you. Give them a call and see if they will replace it without charging you for the replacement. I would also call up bushmaster and see if they can install your barrel on one of their uppers, if you still want the light weight. I think holding your upper together with glue would be a grievous decision. |

I have a Professional Ordnance type 97 carbine. I have had two "material" failures that have been fixed sucessfully. I suggest using some sort of metal "bridging" material, like steel wire in addition to using an adhesive like JB WELD. If it were me I would drill a hole, or holes, in each side of the break. Then glue in the steel reinforcing material, and glue the joint. My lower split along a mold mark down the top center of the ring into which the buffer is threaded. I made such a repair, and it has survived several thousand rounds thus far. Good Luck.
As an additional thought, not knowing exactly what upper you have. Some uppers and lowers do not have perfectly "standard" hole spacing. The Pro Ordnance uppers, for instance, will not mate with any other lower, as the hole spacing is different. Once you make the repair, check carefully to see that the spacing on the upper matches that of the lower. It may be that the fracture of your upper came about because the hole in the lower was offset slightly, and the pressure from the pin, if it was steel, may have been too much for the upper to bear. |

Good luck with that buddy, Vulcan Arms is not known for their helpful customer service, in fact they are quite infamous. best of luck all the same. |

One of the first things I learned on this site was to avoid Hesse products at all costs. THos lowers will break at the barrel attachment point, I have seen pics of them blow out the sides of the upper etc. I suggest throwing it in the garbage as I would see it as dangerous to use.

Yes. I would think that pic alone would tell people to avoid that receiver. A local AR15.com member had his barrel go loose and would wobble around in the reciever in a circle with the barrel nut tightened down. We should get a tacked thread going with pics of Vulcan receiver failures to let people know to avoid them.

Does this mean you are suggesting superglueing the receiver back together? |

WOW!!! After looking at that picture maybe I'll just look into getting a Bushmaster carbon upper receiver.

There is not much wait savings between a carbon fiber and forged aluminum upper.....

Still more likely to fracture at that particular point than a forged Aluminum upper. Carbon fiber has it's limitations, and these uppers are not pure CF but rather a mixture of poymer and Carbon fibers. Extremely minor weight savings. Not worth it IMO. Your results may vary. |

What’s this with you and Carbon Fiber man? Haven’t you learned your lesson yet?

carbon is for gunpowder not uppers.

Just let the pros repair/ replace it for you. Nothing personal against carbon fiber owners here but I still don't trust the technology the manufacturers are currently using. The manufacturers should use stronger composites or metals like titanium or stainless steel in high stress areas. Carbon fiber barrels, handguards and stocks are OK but the receivers still have a long way to go. This is just my personal opinion, YMMV. I'm an aircraft composites tool and manufacturing engineer with 20 years experience, I know nothing.

Dude, do you hit QUOTE as soon as the CA registered in your brain? No offense meant as I'm sure you just had a little too much caffeine but you needed to finish reading my sentence. I'm usually a little long-winded (like now) but not there.

Honestly I would send it back or replace it with an aluminum one. It isn't worth your safety over it.

From what I've heard about Hesee/Vulcan, you would probably be better off if it didn't come directly from them. Usually a vendor would be willing to risk taking a loss to keep you happy even if Hesse/Vulcan won't.
Hopefully you bought it from a third party vendor and they'll take care of it for you! |

Once again....
The AR15 was designed and engineered to be made of ALUMINUM. Not steel, not carbon fiber, not pie crust. If someone were to design and engineer an AR15 to be made of steel or carbon fiber it would be made to take advantage of the STRENGTHS of the material and would be engineered to compensate for the WEAKNESSES of the material. An AR15 made of steel or carbon fiber would not have to LOOK like an AR15 made of aluminum. It might be thinner in some areas and thicker on others. In the case of carbon fiber there are certain area that should be made of aluminum or at least renforced with aluminum in the matrix. These include the barrel nut threads and the lugs for the pivot and take-down pins on the upper. I'll stick with AR15 lowers and uppers being made of aluminum, just like Eugene Stoner designed.
