If that time is when you’re touching off a 300 Win Mag on a trophy whitetail deer, your day is going to be far less than stellar. If you’re getting more into shooting and want something a bit higher performance for lubrication, get a performance oil like Mobil 1 Synthetic or Militec-1. On the other hand, your gun has a large surface area and is regularly exposed to wind, rain, blood, sweat and, occasionally, tears. Grease stays where you put it (it doesn’t run like oil can) but it should be avoided in really cold weather. Gunzilla is a good choice if you’re looking for an all-in-one (cleaning, lubricating, and preserving) gun oil for all sorts of firearms like handguns, shotguns, rifles, and more.

Gun grease can give you longer-lasting protection due to its thicker nature and superior adherence to metal, but it also hardens faster in cold conditions. The reason could be the inhibiting properties in the solvent that prevents carbon and lead build-up and protects the guns from rusting and corroding. A combination of salt, moisture and warmth (even the warmth in your car compared to that outside) is a deadly formula for encouraging rust.

This plant-based cleaner works well at light cleaning tasks and the thin/light film it leaves behind is a good rust preventative. It doesn’t run or gum up even under extreme temperatures, and was actually originally designed for use with machine guns.

The most interesting thing about Break Free wipes was that when I opened the packaging, I immediately got a faint odor of cardboard, followed by a pleasant aroma of almond-flavored coffee. HOPPES 9 SOLVENT IS OK TO USE IN THE BARREL, BUT PARTS CLEANING ETC SHOULD BE DONE WITH PLAIN CHEAP OLE MINERAL SPIRITS (PAINT THINNER, BUT USE MINERAL SPIRITS AS ITS CHEAPER AND LESS STINKY) WITH A TOOTH BRUSH OR A BRASS BRUSH.These oils are generally applied to vulnerable metal surfaces such as the inside of the bore and to friction surfaces like slide rails on handguns and bolt lugs on rifles. THESE PRODUCTS ARE BASED WITH MINERAL OIL AND HAVE SOME PERFUME IN THEM AND SUDDENLY ITS HOPPES LUBE OR THIS OR THAT! The last thing you want is your oil turning into something with the consistency of cold gravy that will then cause your gun to not cycle. Now that you know the types of gun oil out there, you’ll have questions on what you should be choosing. Last I heard it's what Sig uses in their factory and my Sig 516 came boxed with a sample pack of the oil.

However, it’s worth noting that it can thin out and spread a little bit, so you need to be super careful when applying the Break-Free CLP. The good thing is that most of the oils you find in the market work just that the results will vary from one product to another. I can tell you that I now keep a small bottle of Mpro7 in my go-bag, but I still have some CLP in my cleaning kit.Mil-Comm can also be used for industrial purposes and is even used by Boeing for some of their airplane applications.
