Yes but grease for metal on metal/metal on plastic moving parts is better.
If you use the shock oil, use one drop then spread it around with your finger or use a couple drops on a q-tip.
Lighter weight silicone oil should be used in your mags to lubricate your gbb's internals. I have used heavier shock oil in mags but use it sparingly as it will gum up fast.
