What kind and where do you recommend lubricants on my build? I have Hoppe gun oil. I know the barrel and stock should be greased...what do you recommend? Thanks. Hooo boy. You will get a lot of opinions on this. Seems like there are a lot of actually good choices out there. Slip 2000. Hoppes, ALG Go Juice, Mobil 1, Fireclean... I've tried them all. Right now I'm using the ALG Go Juice which is quite a good lubricant. Fireclean was also really good and helps clean up better than Go Juice (carbon doesn't stick as much), but it seems like Go Juice lubricates better and doesn't gum up like the others if you don't shoot or clean your gun for several weeks. Slip 2000 was also really good but Fireclean seemed better to me. I tried Mobil 1 one time and it was ok, too, just didn't clean up as well. Right now, I would say the Go Juice - no science behind that opinion, mind you. I shoot my AR's pretty wet so YMMV. That lubrication guide that Tig linked for you above is what I follow. |

Come on, you don't need no lube!
Hell, I went out to shoot the other day and forgot to lube a new BCG, so I looked around the truck and found a little squirt can of 3 in one and it worked just fine. |

Quote HistoryThanks. How about for assembly? What should I use for inserting the barrel into the receiver and then on the stock threads? |

did something better 2 weeks ago at the range.... pulled the dipstick from my car and used a few drips from that. Motor oil does wonders. I soak my bcgs in Mobil 1. Quick shake, blast of compressed air, and into the upper. Run em wet. |

Excellent. Thanks! Can't go wrong with that. For the barrel nut I used tetra grease and in other general areas of the build. I forget where I got that from I think the Fulton armory ar15 assembly book. It seems like a good initial product to use so nothing locks up. |

Oh this is going to sound crazy but I use red loctite for the extension into the receiver.

I saw one video show with a grease and another video it went in dry. |

AFAIK Aeroshell 33 does not meet the mil-spec.
You want Aeroshell 33MS which has been renamed (I think) to Aeroshell 64 to avoid the confusion between 33 and 33MS. |

Quote HistoryDo I need to put any grease on the barrel part that goes into the receiver? I saw one video show with a grease and another video it went in dry. No. You do not need to grease up the barrel extension, only the threads on the upper receiver itself. If you have trouble inserting the barrel extension into the upper receiver then it would be acceptable to use some light lube to help ease it in. I recommend lithium grease on the receiver threads. SLIP2000 on the extension if needed. |

Do I need to put any grease on the barrel part that goes into the receiver? I saw one video show with a grease and another video it went in dry. That's what I was referring to earlier. That's called the "extension" of the barrel. I put a dab of red loctite on it and put it into the receiver. It sounds nutty and no, red loctite won't cause it to be any harder to remove but it will help with accuracy a little. It doesn't need grease and depending on your upper it may just be really easy to go in. I know BCM makes their receiver a little tight while others tend to just slide in very easily. I recommend picking up the The AR15 complete assembly guide. It will help you much better than coming on the forum (or watching videos from unknown persons) as you'll have opinions from a expert builder who does it for a living: http://www.fulton-armory.com/thear-15completeassemblyguidebuildyourownar-15.aspx Edit: I should also add that grease and chemicals that you use in your build is not as important as the torque values that you apply. I recommend investing in a proper torque wrench, proper vise, proper ar15 wrench that you can connect to the torque wrench, and block for your build. |

I use grease, because grease is best.
Used sparingly it outperforms oil and doesn't foul up the rifle nearly as much. |

I don't use anything too fancy. I just a synthetic motor oil for most stuff. On the barrel nut I use a EP Moly grease you can pick up from any auto parts store.

I actually use this stuff where carbon collects, in the gas key, etc. Carbon comes off easily. Also high bearing areas, 1911 rails, and so forth. better than any petroleum based product I've ever tried.
https://www.amazon.com/dp/B002KH0YDY?tag=vglnk-c102-20 the viscosity stays the same from about -30 to 600. It's not temperature dependent like petroleum based. It's also not messy, it won't stain your clothes, or give you that grungy feeling. At least when it's newly applied. Nor does it run, or harden. And a thin film is virtually a permanent rust protector in storage. |

For AR-15's I spray my BCG wet with Breakfree CLP and wipe off the excess. also lightly coat the charging handle, at the range just before shooting

If, like most commercial manufacturers, the recommendation is for a "high quality firearms oil", then you already have it in the Hoppe's gun oil. |

Really anything. I stick to superlube grease with PTFE or Royal purple 10w-30.
