Recommended Silicone Oil for GBB

[iarenick]

I am waiting for my KSC Glock 18c to come through the mail right now (Just ordered from PrecisionAirsoft.com), and decided to use PC Duster gas to power my gun. It was recommended to me to use 100% Silicone Oil to lube the magazine before I fill it with the gas. What grade of Silicone Shock Oil is recommended?
They seem to cary from 10 - 70 (Weight). What is the difference in using each one for your gun? Do diffrent types of guns use different grades?

Use 70wt on your moving parts (think of it like an engine...heavier lube is beneficial) and 10 or 5wt on your mag seals.

Those are the standards...as you use your gbb more, you can buy other weights to try and find your own ideal, but I use those standard ones, and I've never had a problem.

I use the stuff MadMax at Airsoft Innovations sells. You can find a link to his site at the top of the page under Canadian Retailers.

Actually, I wanted to clarify a common misconception. I'm hoping Mad Max can clarify chime in as I intrepret this from what he has told me at last years orientation.

Silicone oil is not a good GBB luber in regards to the moving parts! My understanding (from MM) is that it is molecularly thin and when put on metal or moving parts thins itself out providing very little lube for metal on metal rub.

Silicone oil is great for keeping your plastic and rubber seals intact though (that's why we drop it into the gas chamber). For metal on metal parts use Lithium or Silicone grease instead. Just wipe it on sparingly and clean it once in while to remove dust, dirt and other contamanents (sp?).

I would think that using any sort of grease on a GBB would tend to slow the mechanical action (slide recoil, etc) down slightly due to the viscosity.

I've been using silicone oil on my GBB and have had no problems thus far.

so... basically, I should get 10 (for my mag seals) and 70 (for the actual gun's parts?)?
Thanks guys.

Wow, these forums are so much better than the forums at ArniesAirsoft.co.uk. Geez, hehe, I made a little joke (nothing bad) and I got instantly temp. banned! :banghead: .

North America > United Kingdom :nod:

You'd be suprised dude, that can easily happen here too.

Before you make that assumptoin, you should really try that joke out on us. :grin:
But yeah, I use really any weight, I found that the lower needs to be reaplied more often, which is a given, but none of it is overly affective, it all just gets dragged off anyway...

Heavier = Less need to reapply
Lighter = Faster kick, but isn't affective for long...

I suspect the opposite is true. The grease will help lube (slippery surface) the metal on metal contact causing the GBB to speed up it's action. Using silicone is pretty much like using nothing and the metal on metal rub would cause wear and slow down. That's if I am correct (If I'm wrong on silicone being bad, then your assumption is more accurate)

Goes to prove that many of our GBB can take a lot of abuse. They don't need to have a lot of lube and will function with the little that we give.

Is there anything avaiable at your local hardware or Homedepot you can use as oposed to ordering it?

usualy hobby shops all carry silicone oil

[Dog Face Killer]

k

[Janus]

Light silicone oil is a commodity that should be available anywhere.

Any hobby shop worth their salt can get you your appropriate wt.

agreed, grease for metal on metal. oil for the seals, although i use lithium grease on everything and add a drop of oil from mad max to the mags when i fill them up

Silicone oil has the strange property of not staying in place. It will spread continuously until it has become a molecularly thin layer. This is a good property for penetrating cracks and spreading evenly (good for rust protection), but it's kind of crap for providing higher pressure lubrication. Perhaps it's most useful property in airsoft is that it's inert and doesn't attack many plastics or rubbers. It's good for conditioning rubbers and preventing them from cracking which is why I recommend it as a seal conditioner only.

I find that a very light application of teflon or white lithium grease works much better for slide rails. I dab on a bit onto slide rails. Install the slide and cycle it a bunch of times to spread the goo then wipe it off with a paper towel to leave a very thin film. Gobs of grease can pick up sand and dust which makes for an abrasive emulsion I call "gun smegma". I am also experimenting with graphite powder which I lightly dust onto the rails before the cycle and wipe. The graphite makes for very dry film. You can wipe nearly all of it off after cycling the slide. The only downside is that you have to thorougly wipe it out of the external surfaces because it can transfer to holsters, gear, and eventually smudge things like a sofa or your face. You can find graphite powder at Crappy Tire in the automotive section. It's used as a door lock lubricant.
