    I have been seeing a lot of builds going on lately and I know we have also had a bunch of people asking about buying vs building.

    The AR is an easy platform to take care of but, for a person that is new to the AR platform it can look like a lot to take care of.

    Here we are going to go over how to lube your ar so you get the best lube possiable and get it all in the right spots.

    I use a combo of Grease and Oil. I have and love Wilson Combat Moly Lube for my grease and Mobil 1 0w-40 fully synthetic motor oil. It goes on easy and stay put.

    First area we are going to talk about is the bolt. I put a drop of oil on the Gas rings and use my finger to work it in and then work it on to the back of the bolt. You can see where in the picture below.


    Next we will go over the bolt carrier. the bolt carrier has 5 spots I lube with a touch of grease. You will be able to see them on your because they will shot some wear from the bolt cycling. I have pointed them out in the picture below. I use grease here because this is a high friction area that needs all the lube it can get as it is a STEEL bolt carrier riding on and in an aluminum upper.

    lube

    After 4 or 5 shoots I take brake cleaner and blast the trigger group clean, let it dry and them reapply oil. Seems to wash all the grit out. I generally put the cam pin back in WET and give the entire bolt a good coat and then wipe if off gently so its fairly oily but not dripping. The carrier just gets a good wipe down as well leaving a fair amoujnt of oil on the bottom. Seems to work for me and I'm not getting my shooting glasses splattered with oil. NICE POST TANGO!

    Where did you pick up the moly lube? I did a quick google search but only found some forums discussing it with no links to the actual product.

    I thought you were supposed to just store your AR in a vat of used motor oil? Pretty sure that's what the Air Force does with theirs. :D

    Nice writeup with pictures, very helpful. Thanks!

    I didnt know the AirForce had weapons w/o wings attached. Nevermind, yes I did because they constantly had NDs while on patrol w/ us. They need to keep them in those vats :D

    I have lubed mine like this since I got it and she runs fine. I ran 5 mags through it as fast as I could slap the trigger and she never hiccuped once. I don't like the run wet type of thinking. It is good if you are shooing an A1 with mag after mag of full auto fire.

    For my kind of shooting this method works great and you don't end up with a sloppy mess of a gun.

    Good advise, except one area. You should not use oil/grease on the gas rings. They will get gummed up because of the high heat/pressure. Sentry Solutions makes a powder lube that can be put into the gas rings and will not gum up.

    My Mobil 1 came in that huge bottle, of course. I pur some into the cap and soak patches to wipe onto some surfaces. But what do you use to drop a single drop onto, say, the trigger springs? Just a simple Walmart eye dropper?

    A syringe would be a good way.

    Great Write-up Sir Tango!

    I use a small oil can I found at the auto parts store to drop tiny drops of oil.

    I use a couple of these 1 oz, needle nose oiler bottles for tight jobs needing just a pinch, with Amsoil synthetic, or you can use some Mobile 1 synthetic in it as well.

    I have a nurse as a wife so I have an endless supply of 5cc, 10cc and 60cc syringes So that is what I use. I also get her to nic me some IV catheters for the deep points. 18 or 20ga work the best.

    I love that grease too, but if you need some on a Sunday before a range trip, go to your local auto parts store and get "White Lithium Grease", it works great and one $5 tube lasts forever.
