From a lubrication standpoint....guns are not very demanding systems....
They are low temp, low duty cycle, low pressure and are maintained frequently.
Frankly.... it doesn’t matter what the hell you lube them with..... as it’s going to get replaced or cleaned in 500-2000 rounds anyways.
I’ve ysed everything from RemOil, clp, ATF, froglube, cooking oil, 10w30, Teflon lube,3-in-1,etc.......I have not been able to tell a difference in performance between any of them.
When it comes to firearms.....lube is lube.
“Designed for firearms” is marketing BS..... most of the gun lubes you find on the market are just rebranded general purpose lubes sold at a HUGE markup.
I can almost guarantee 90% of the companies selling gun lubes are not doing ANY chemical engineering at all..... why would they? Why would they spend a boat load of cash developing a lube that does the exact same thing as an existing product.....like I said, when it comes to firearms, they aren’t demanding systems.
I run 10w30 almost exclusively.... works great and have never had an issue from it
I will give you my humble opinion based on my experience, I will say that not all lubricants perform the same. When teaching armorer & instructor courses, we approach the maintenance and lubrication from the perspective that if lives depend upon the firearm, then it needs to be set up and maintained so it runs with 100% reliability in all field conditions possible. With this in mind, field conditions will vary, and the field conditions need to be taken into great consideration when looking at what lubricant works best, and what maintenance needs to be done.
I am not an engine mechanic, and by no means an expert or engineer on engines, but I do know several people who are engineers that work with engines and lubrication I can say that in conversations with several Engine Mechanics, and Mechanical Engineers that do research on engines and machines, there is a huge difference in engine lubricants when comparing conventional motor oils to many of the synthetic oils. Some of the things that have been found is engines run slightly cooler when ran on synthetics, and that there are less metal particulates found in the synthetic oils as compared to convention oils when the waste oil is analyzed. You will also find that engines generally go longer between oil changes when using synthetics, as compared to conventional oils.
I do know a few things about firearms. We lubricate weapons for 2 main reasons, first to reduce friction, the second is to protect from corrosion.
When it comes to corrosion protection, some lubricants have a rust inhibitor and some don't. I can tell you from experience that Breakfree CLP lasts about 30 days on our police patrol car guns for the environments we have in Minnesota. Remoil and Hoppe's oil lasted about 6 weeks. Militec-1 didn't perform well in our colder months, as I would find rust on our Benelli M1-90 ghost ring sights a week after they were wiped down, where you could still see that the parts were wet with the Militec-1, but there was rust coming through. The best corrosion protection we have found for our Officers has been Slip2000 "EWL" Extreme Weapons Lube.
When it comes to erosion protection, we need a lubricant that reduces friction where metal rubs metal. Basically all lubricants will reduce friction, until they either freeze, dry up, burn up, or get built up with fouling to the point they are no longer acting as a lubricant. Any liquid like water, soda pop, beer, will act as a lubricant to reduce friction until it evaporates. What I have found is that lubricants like Hoppe's oil and Remoil that work well on a bolt action rifle or shotgun, don't seem to fair as well on a semi-auto AR15 or works on a select fire M16 / M4 due to it burns off faster from the heat generated on these rifles.
When teaching armorer and user courses on the AR15 / M16 weapons system, we have people insert a just the bolt carrier (No bolt, cam pin, firing pin or retaining pin) into the upper receiver, and you will find that it should freely move back/forth through the upper receiver, only riding on the rails of the bolt carrier that are located at 2, 4, 8, 10 O-Clock, with the large flat section of the bolt carrier at 6 O-Clock pushes over the hammer during the cocking cycle.
Now insert a complete bolt carrier assembly into the upper receiver, and you will see that it travels forward into the receiver freely until about the last 1/2", which is when the 7 Bolt Lugs enter the Barrel Extension Lugs, and the Bolt rotates clockwise (If you are behind the gun shooting it), causing friction. When you pull the bolt carrier rearward, it will have the same friction for about 1/2" as the 7 Bolt Lugs rotate clockwise and unlock from the Barrel Extension Lugs, then the bolt carrier assembly will travel rearward freely.
What this shows is that the bulk of the friction is in the 7 Bolt Lugs locking and unlocking with the Barrel Extension Lugs, and this is why the 7 Bolt Lugs need to be wet with lubrication IMHO. So the use of a quality lubricant where you have friction is what is needed. My preference is a lubricant that doesn't gum up or burn off, and will run well in hot and cold weather. All lubricants will run in hot weather, until many of them evaporate or burn off, hence my preference for a synthetic. Where a lot of lubricants fail is in colder weather, CLP doesn't work well in cold weather and is why the Military specs in their the manuals that in cold weather to use LAW. I am in Minnesota, where we have 5-7 months of winter, and we can change from warm to sub-zero in the same day or week, so I know that my staff will not usually take the time to do daily weapons lubricant changes as weather changes, so I prefer to use and have our staff use a lubricant that works in warm and sub-zero temp weather, that also has a good rust protection qualities, and that lubricant for use is Slip2000 "EWL" Extreme Weapons Lube.
