Come on guys, we're on an oil forum and you don't know better then that!
The only thing that the gun specific products offer is cleaning, but you can get dedicated products for cleaning the gun. Then you lube it. These do it all in one step products are a compromise.
On the weapons that I have the like grease I use Mobil 1 red grease as it runs a little more then most grease.
On the parts that require oil I use Rotella 15w-40. I have yet to have a problem over a couple thousand rounds.
