MILITEC-1 makes a lubricant for weapons. The other companies make everything from gun cases, video programs, clothes and knapsacks to whatever. I haven't researched them all.
If your question is about MILITEC-1, then I can help because I have used their product for over four years.
Which company are you referring to?
A short search finds:
Well, that gives an idea of what I am asking. I see a number of claims that so and so bonds to the metal, makes it slicker than whale sh**, etc. so that nothing sticks, no copper buildup, no fouling, etc. Makes me want to wear hip waders to just read the ads.
I understand throat erosion is caused from combustion gasses and partially burned powder wearing away the metal in the throat. I am just looking for something that will really help reduce friction, increase velocity, and attract purty babes. LOL!
