Most of the time I use Mobil 1 synthetic grease. Much much cheaper than anything made specifically for guns and is rated down to -40F. I also put a little bit on the sear engagement. Everything thing else is usually sprayed down with Hornady One Shot as it's a very good dry lube and rust protector. The reason I've gone to that regiment is because oil tends to migrate and creep in to places it's not supposed to be and doesn't stay where it's needed. Grease and dry lube tend to not run off.
