Just add lube.
Specifically at the exhaust ports on the carrier and all 4 points where the carrier slides in the receiver.

I thought that on the moon, the rifle will wear excessively, whether you lube it up or not...

Why would you think that?

Why would you think that?

Considering how poor mooninite ray gun technology is, I'd take an AR-15 in space anyday!

I know of the 4 slide points, but had no idea about the exhaust ports. Do you have a picture?

I have a lot of pictures.

What you are doing is lubing the bolt and gas rings where they run in the carrier.
You can completely lube an AR without even opening the upper from the lower.
A few drops on top and bottom of the carrier with the ejection port cover open and the carrier closed.
Then lock the carrier back and drop a few drops on the back top rail and the back bottom rail and work the bolt carrier a few times to spread it around.
Then a good squirt into each exhaust port.

Yeah pretty much that's what I do. I just don't really know what is called what.

It's the two holes facing out of the ejection port.
Just behind the cam pin on the SIDE of the carrier in this picture:

Ahhh... I see. I guess it's there so that you can actually lube the AR w/o separating the receivers, like you said. Thanks!!

No.
It's there to exhaust the extra gas from inside the carrier to outside the receiver after the carrier starts moving.
The carrier is a short stroke gas piston that's just housed in the receiver instead of out on top of the barrel.
The exhaust ports vent excess gas just like the exhaust ports on a gas piston system except on a gas piston, they vent it inside the handguards.

It just happens that they are very convienently located in the ejection port so you can lube the bolt without taking the rifle apart.

I guess it's 2 birds with 1 stone.

Vtec, read Pat's article on the first page. It'll explain that plus much more.

The BCG should have a film of oil on it. Those 2 little holes when the bolt is closed should be used to put oil in. Everywhere metal rubs on metal

Also, in case you're wondering about the G and L

G- generous lube, aka a thick film
L- lightly lubed, thin barely visible film
