I'm working on a couple uppers, ordered all the parts and tools and forgot to order grease for the barrel installation. Will this fit the bill?

Aeroshell 33MS if you want to be US-Mil Spec, forgot once you talk about grease the flood doors open for the mass. |

Especially when you mention Aeroshell 33MS. It seems that people who start a crapstorm of dissing posts over someone using an inexpensive stock on a build ("you spent $1K on your rifle and put a $50 stock on it??!?!!!!11") still like to go out of their way to go ultra-cheap on grease for their barrel nuts. If you have to spend $30 on a cartridge of AS 33MS, you're not bothering to shop around at all... I still don't get it.
[Aeroshell 33MS if you want to be US-Mil Spec, forgot once you talk about grease the flood doors open for the mass. OP, I recommend against any automotive grease for a number of reasons. Aluminum-on-steel applications require specially formulated greases. Such auto greases are rare, and you're not going to find a 3 pound tub of them at Wal-Mart for $2.50. Umbrella Corp offers a small, 1/2 oz. container of Aeroshell 33MS for $3. With shipping it will probably set you back a bit more than $5, and it is enough to build a bunch of rifles (though it is not suitable for personal lubrication). |

So break this down, use the off the shelf stuff and run the risk of the barrel nut binding on the receiver, use the mil-spec and I'm golden. ETA: I ordered the 33MS, now I wait.

lol run the risk.....I personally have Aeroshell and other lubricant's in my shop, and unless someone ask for specifically I use whichever one.
High Temp = Check Mineral Base = Check Non Metallic = Check ....... that is as far as it goes...whatever this thread will devolve into old ass people bickering and someone saying "Well Colt uses this" or blah blah blah.... It is basic science....if you look at the chemicals used in both from the MSDS sheet you can't go wrong...Mil-Spec just means "It is what the military inspected and approved at the time of specification"...... Ask an armorer on the front lines, if he uses Aeroshell.....I guess they must be dumb lol. |

Here is the PDF from 1968 on the grease specification from the military.

| I own an auto parts store and was wondering what a good replacement for this would be so I called Valvoline and asked them if they had an equivalent to aeroshell 33 and they don't but the closest that they make to it is what they call there Palladium it comes in 14.1oz. tubes and the part # is 70112 and it doesn't have any graphite in it. I carry it in my store because I have customers that require it they are mining, industrial and construction companies. We sell a tube over the counter for $4.49. Just my .02. |

I bought way too much from this site: http://www.skygeek.com/5067068.html
I don't need 14 ounces of the grease, but it was only $15.50 plus shipping, and I had it within a few days. Given the overall cost of the parts of the rifle that I'm building, as well as the wait times I have had to endure, I didn't mind a little overkill. After all, what's another $25 (with $10 shipping) on top of what I've already spent? If someone needs some of the grease, and you're local to me (Dallas, TX metro area), I'll freely share some. I don't want to mess with repackaging and shipping it, however. I guarantee that I will never build enough rifles in my entire lifetime to need the entire 14 ounces...

I just bought a tube of that aeroshell 33ms grease. More than everyone I know will ever likely need. If you like, you could send me a small empty container with a self addressed envelope with return postage. I'll scrape some out of the tube and send it to you for free. I'll extend this offer to a several people. PM me if interested. I imagine you could ship 1/2-3/4 ounce for pretty cheap. This is assuming that 1/2 oz container you can order online isn't cheaper than some shipping to and from me.
Also I am a little pissed I just found this thread and found out about the umbrella grease. I placed my order not even 10 minutes ago for the mega tube of doom. |

Like I will ever need nearly a pound of Aeroshell 33MS grease.

I used antiseize with copper on mine................I know everyone says its going to cause galvanic corrosion but i used it on an aluminum barrel nut and aluminum free float rail so i think i'm good since its aluminum on aluminum.........Right? I don't think you need to worry about galvanic corrosion with this combination as long as your antiseize doesn't have graphite in it. Graphite can hold atmospheric moisture and create the electrolyte needed to cause the galvanic effect between dissimilar metals. However, copper has a much higher potential difference from aluminum than steel does, so the grease itself, given an electrolyte, could cause the corrosion to occur. Aluminum has an "anodic index" of about -0.85, while steel's index is about -0.95, a difference of 0.1. Copper's index is about -0.35, a difference of 0.5. The general advise about greases and aluminum is to avoid all metal-bearing greases, including copper-bearing grease. |
| It was permatex brand and it says on the package for installation of spark plugs into aluminum heads. Wouldn't the other things in the anti seize like the petroleum,mineral oil, calcium etc affect the galvanic corrosion properties? Its not straight copper on aluminum its suspended in a solution. |
|
I deal with galvanic corrosion between metal components sometimes at my day job (I'm an engineer). Some pretty nasty stuff can happen, especially in a conducive fluid like water that can speed up the reaction. On an AR I don't expect fast or much corrosion, but for a gun I will have for decades I want to ensure I don't get a galvanic couple with graphite. It's potentially overkill, but this isn't complete snake oil. That being said, some less expensive non-graphitic greases are likely okay.
If you want to learn a bit more the following Web page has some info. I find the chart to be of particular interested. Galvanic chart |

Put a small dab on your pistol's slide rails. Oh I am sure I will find other uses for the grease. I still am unlikely to ever use the entire 14 ounces of grease. I think I'm set for life. I plan to share with some other buddies who are building AR-15s, and the offer stands that if you're nearby and want some, let me know. If you want to mail me a container, I will share with you, although I'd appreciate you paying postage since it's a pain in the ass for me to go to the post office and ship something. |

how about Super Lube?

Why is this a ONCE A WEEK question?  Seriously? Because newbies don't or can't search for this sort of thing, and because we old tarts generally can't agree that using a MIL-G-21164 standard grease, as called for in the TM is better than a substitute (whether that substitute is "good enough" or not). |

...Also I am a little pissed I just found this thread...
Agreed. The threads I read on barrel to upper assembly didn't mention this, saying only to use a quality lube. Of course the one I picked has suspended graphite. Well, it's only been a week, and the rifle remains at room temp while I await my BCG, so no added heat to drive the galvanic. This is recoverable. Just wish I'd caught this thread earlier. But VERY glad I cought it now. Order in to umbrella. Time to strip the upper & clear out the existing grease. When I'm putting it back together,I may as well try that shim thing from this month's American Gunsmithing Assoc. mailing. |

Galvanic corrosion occurs when two dissimilar metals in an electrolyte touch, and an electrical charge is introduced; plus the further away the two dissimilar metals are apart on the galvanic corrosion chart, the more intense the corrosion of the less noble metal.

In case anyone is curious about the shell 33ms 14 oz tube pricing and delivery. I just ordered from sky supply usa. With shipping a tube was 22.62. I ordered Friday night and received today in CT. Shipped from Pa.
For the nay sayers, galvanic corrosion is a very real thing and prevention of it is factored into design and material selection. People aren't just making it up and this discussion isn't gun forum nonsense, it's material interactions and chemistry that happens to be on guns. I doubt anyone has a vested interest in the aviation grease business. People are just trying to help each other out and share knowledge, which has is the point of most forums. I will admit the rate of decay on an AR is probably very low and worrying about a mil spec grease is likely overkill, especially over a short time frame. However, for a hot joint that may see some moisture over years / decades I am not going to insert a galvanic couple, especially when the perfect stuff costs 15 bucks more than regular grease and I now have a lifetime / friend lifetime supply. There are several threads on this, which is why it wouldn't be a bad idea to have a brief rundown amended onto a guide thread or stickied itself. People don't have to buy the expensive stuff, but noting the pros / cons can't hurt. Just noting that you want a molybdenum disulfide based grease will likely help people. On every forum people ask about the appropriate grease. Being a new AR builder I read through the stickies / guides and didn't see this specifically. I could've missed it though. The search doesn't always work the best due to its brief scope and time frame , unless you use the Google version. |

Lithium refers to the lithium soap used to carry the oil and additves. Mix up the two, and you have a lithium base grease. On a side note, I have a 1oz. jar of Neco Moly Slide for about 8 years now that I use to install barrels and lubricate triggers and sears and it isnt even half way used up. |
