M14S/M305 vs M1 Carbine lubrication

[Rule 303]

With the Norinco M14 platform, it is recommended (nay, more like mandatory) to use grease on all operating slide mechanisms.

With the M1 carbine, both aftermarket and TM publications recommend oil only.

Since both these operating systems are virtually identical, should they not be lubed exactly the same?

Go for it!

On my legit true chinese M14 I've run my gas system dry for a few time at the range and always came back with some rust inside. Last time I decided to go against the mainstream recommendation to run it dry and lube with tri-lube spray every single part, with generosity. My cloth was drenched. I waited for 15 minutes then wiped everything down. I've never seen any rust anymore since then and the system run just as good as it ever did.
I still applied grease where it needed to be.

Virtually identical???..............The 7.62x51, 147 gr round has a velocity of 2733 ft/s, 2437 ft-lbf of energy, and generates a max. pressure of 60,191 psi. Compare that to the .30 carbine, 110 gr round which a velocity of only 1990 ft/s, 967 ft-lbf of energy and generates a max. pressure of 38,500 psi. Ones a big boy round, the other is not. Likely why one recommends grease and the other recommends oil.

Funny enough, oil is recommended on the m1 carbine for battlefield conditions. That was way back when though.
I wonder if the nazis with the big boy bolt action were laughing when the .30carbine was punching their helmets and knocking their lights out.

The cartridges are different, the rifle action is similar. Same for the mini14.
Use grease and oil.

It might have been way back then but it was recommended to use grease in the M1 Garand as well so its not like using grease was a foreign concept to anyone. My guess is that Winchester had a reason to specify oil for the carbine as opposed to grease.

For me its oil on my carbines and grease on my Garand.

My carbines work just as well with grease as with oil. I use the U.S. GI grease that comes in the little pots with the screw cap. A little goes a long way...

However, if I was shooting in the dead of winter....a light oil or graphite lube.

I use only oil right now to. CMP guys seem to think either way is fine.

TM publications recommend oil only.

I guess some recommend grease too(mainly for raining conditions). Again, going off what some CMP guys quote.

I would think that the M14 is more comparable to the M1 Garand. Your suppose to use grease on a Garand...So I would say put grease on your M14
