View Full Version : AR 15 Lubrication points

August 15, 2012, 09:20 AM
Please tell me where are the places that need to be lubed at regular intervals. I have a new M&P Sport. Pictures or a link would be most helpful. Thanks in advance.

If it slides, grease it; if it rotates, oil it.

Here is a link to a publication that covers
all sorts of AR 15 topics. The lube part
is on page 12. It is pretty straight forward;
it was written for the average GI.:D

I've never seen any need for grease on an AR.

Greases are a bad idea in the AR, because it will just gum up with carbon dust.

I would not recommend that. The AR is not like the M14 family - it prefers oil.

I just squirt a crapload of Slip 2000 into the ejection port and all over the BCG. But seriously, see above post and save the grease for the M14

All I do is spray a nice coat of REM oil on the bolt carrier before I hit the range and slide her back in, good to go.

Too much lube and you are making a grit soup that attracts dirt and sand that might cause more wear to areas on the rifle.

I've never had a problem using grease on the cam pin slot, bolt lugs, and bottom/sides of BCG. My current choice of grease is red wheel bearing grease out of the tub I use for packing bearings.
My SIL did 2 tours in Iraq and his unit's plan was oil is good and cleaning is time well spent. As long as a mag was in place, the dust cover was closed, and muzzle covered, very little dust got into the action. A good amount of oil prevented the carbon from siezing up any parts during high volume "events".
I don't use my AR(s) in that fashion-not yet anyway. If I do, I'm going to follow his recommendations until I find differently.

Over lubrication is a myth. Just keep it WET!
You can go like 40K rounds without cleaning. ;)

Not so much a "myth" as it greatly depends on where and when you received your training.

Pat Rogers' reply to the question "What causes an AR bolt to fail to return to battery?"-- "Generally lack of lube, because there are still idiots who want to run their guns dry."

I know Pat Roger's opinion on the matter and I agree. What I meant in my previous post was there was a time when the official military training advocated running minimal lube for dry dusty environments. Over time that has changed.

FWIW, I've used grease and oil and never noticed a difference---both work well. I understand the different properties of each but I've never had an issue with either. The key really seems to be---keep it lubricated.

Striker1, you're absolutely right.

August 16, 2012, 06:24 PM
Yep. Run it wet. I just use some CLP and watch it drip.

August 16, 2012, 06:37 PM
when I was in the Marine Corps
the ONLY lube we were ever given for the M16A2 was CLP
it is all you need for this rifle
clean it
dry it
lube it with clp
same stuff cleans and lubes
sent thousands of rounds down range like that under expert eyes supervising

I've always used a light gi rifle grease on the carrier rails and cam pin. A little dab well do you.
