I think I've read that the gas tube and piston need to be dry and free of anything, oil included, for it to function properly.

I did a complete teardown on my Marstar SKS and found gobs and gobs of grease (had the consistency of axle grease) inside the tube, on the piston and spring. Got every last bit out. The tube, spring and piston are perfectly dry. Is this the correct state for the rifle to be in to go shooting?

A light coat of Rem oil won't hurt a thing, and certainly helps prevent against corrorsion. You should be cleaning the gas system after shoot anyway.
 
Gas system needs to be dry. No light coats of oil, nothing. Bone dry. A coat of oil raises pressure and turns to a sticky gummy mess which can cause FTE in the rifle.
 
How do you guys clean your gas tubes? That thing is such a pain in the ass! Such a weird shape, cleaned mine last night, every time I clean it differently hoping it will be easier than the previous method :(

That grease would just be the cosmoline. It all needs to come out, and I would pull apart the bolt / pin and clean all that too.

There is a sticky'd thread about getting the cosmoline out of an SKS.

yup, did it. Palmolive, brush, hot water everywhere, finishing touch was with a couple of kettles of boiling water. The pin rattles and the gas system rattles.

I used the brush and rod from the cleaning kit, palmolive and hot water. Then I used a kettle of boiling water to rinse out the tube. Carefully.

Bull####. I oil the hell out of my gas system, it'll rust otherwise. No ill effects whatsoever. Maybe you'll have issues if you don't clean it every time you go out shooting, but that's pretty unintelligent considering we all know milsurp is corrosive.

In any case, hasn't this been done to death? We have a bazillion of these threads, a quick search would've told you everything you needed to know on this subject.

Oh really? I searched "sks gas tube dry" and nothing came up. Then I seached "sks gas tube" and a really really long thread called "sks basics" and "sks accuracy".

So silly, me, I asked a QUESTION on a DISCUSSION FORUM. :eek:

Thanks for your help and have a good day.
 
ok fellas, play nice .

i who live in the wet coast need to have my gun well oiled between shoots so yes, i do oil my gas piston but before firing , i do wipe it off lightly.

x2

I clean the piston and tube really well in solvent, give a shot of WD-40 then wipe dry before I put it back. Oil mixed with gas, heat, and powder residue builds up and is difficult to remove.


I don't see what the big deal is about this post? Someone is looking for an answer, why not give it instead of a pile of sarcastic BS? If it bothers someone to read the same thing a thousand times, then stop reading it. Just keep surfing. This site is complex and has a learning curve to navigate it properly. And worse for the newbie's, there is always some butthead who feels his babbling is more important than the actual posted topic. If you don't like the post, F*** off and go read something else.

Dry winter here, dry home with low humidity, but all of my rifles wear a very light coat of oil, so I do feel kind of weird leaving the gas system dry after cleaning it.
 
Clean your gas system and apply a light film of oil after shooting and you're golden. I've never had a problem doing it that way. I have found rust when leaving it dry though, for what it's worth.
 
Before I go to the range, I disassemble my sks and wipe down any residual oil on the piston and and around the gas system. After shooting, I clean the rifle thoroughly and lightly oil most moving parts including the gas piston.
OOps, same as above;)
 
Otter, I oil everything,regularly shoot 300-400rds a session without a hickup. Soot/fouling can and will build up on the face of the gas piston but will come off with a soak in solvent. Hot water to soften deposits,scrub or dissolve deposits off,oil everything and check it's condition in the gun cabinet about a week later to ensure no rust is forming.....that is of course if not going back to the range:D my 2cents
