Greasing an ar?

[zipper89]

Should the BCG be oiled and buffer spring be greased in a direct blowback ar?

 

[Denny347]

No

I'd avoid oil or grease on the buffer spring.

Go light on grease around the BCG where it contacts the upper. You can liberally oil the BCG with something slippery that wont grab too much soot. Brand of oil varies from person to person.

Oil. From my experience, AR's aren't a fan of grease. Really like most other firearms. Kind of turns into a nasty crud after shooting.

Whatever you use inside of the AR be it OIL or GREASE will make it's way to the buffer spring as the firearm cycles regardless.

I use a very light grease [as in, so thin you can't tell there's grease there but the surface is slick] on the upper where it's silver from contact and then oil the BCG liberally but not so much that oil goes flying everywhere the first time you fire it.

I personally use a little bit (applied with a toothpick) on the bolt cam pin. The Bolt carrier rails get just enough CLP wiped on with my fingers to look shiney. Two drops of CLP in each hole of the bolt carrier to keep the gas rings happy. That said, notice we are talking about extremely light quanities. Don't over lube an AR

I shot matches, and shot enough to wear out a Krieger SS top quality barrel about once a year. I used the same bolt for three barrels annd was shooting fine when I sold it. Nothing ever wore out.

If you are in dusty combat conditions, running everything dry is less damaging than dirt sticking in the lube.

A can of Mobil One Synthetic will last a long long time.

i Guess my real concern is that BCG and the upper. metal on metal.

I use Remoil.

I use Remoil.

RemOil sucks.

When it drys out it leaves a gummy residue.

+1 to this! I've gone from RemOil, to CLP and now I'm using Slip 2000 which I really like!

 

[PKendall317]

Really though OP, you just need to use something like CLP or Slip 2000 and you're fine. I'd stay away from RemOil. Other products on the market are M-Pro 7, and Frog Lube which I've never used but they work well from what I hear. I've never tried this but I know some people use 10w-30 motor oil on their BCG's.

 

[SaintsNSinners]

I use moly grease on all my guns... no problems so far

 

[SILVERBACK]

Green Grease on the Bolt carrier rails and royal purple 0w-20 on every thing else.
So far never one issue, cheap one tube and a quart last a loooooong time.

I have never had it leave anything other then a slick surface behind. Maybe I do a more through cleaning? I don't know. I like it because solvents remove it and it doesn't leave a oily film behind that stuff sticks to. I have 20 or so guns that I have used it on since they were new. We all have our preferences. YMMV definitely applies.

Remoil is junk.


I like to grease the buffer spring heavily. Makes it smoother and quieter. I also have a parts washer that i use to clean it out so i am not worried about how dirty it gets back there.

+1 On Mobil One Synthetic..

A can of Mobil One Synthetic will last a long long time.

Small bottle of it on my bench. Every semi-auto that I have gets a 'Q'-tip soaked with it on the internals..

Works for me!!..Bill.

 

[irishfan]

I use mobil 1 grease on all of my guns metal on metal areas and never had a problem. Just about anything that needs oil on any gun gets a q-tip of mobil 1 synthetic.

 

[Tombs]

Put a dot of slip2000 on, spread it out with your hands, and keep applying until it won't hold anymore without dripping.

I do this for practically all metal parts in firearms. No need applying it to the buffer or spring.
