Sorry if this has been asked before, but I’m curious. Which of these options if the best “all purpose” product for a variety of weapons (AKs, ARs, Mosin Nagants, Mausers, Shotguns, .22s, etc)
Which and why?
Best for what, Cleaning, Lubrication, Corrosion resistance?
None of your choices are spectacular in any of those categories as it is.
Lubrication and corrosion resistance mostly. I use water and Hoppe’s #9 to clean
Your going to read a lot of good things about Frog Lube here.
Ballistol an oldie but a goodie, especially on those old war rifles.
Ballistol for my normal cleaning and lubing needs. But I did mix some Mobil 1 and ATF that I will try in near future
Frog lube is a great lube, but isnt so good on corrosion. Fireclean is my new favorite. FP-10, Mpro7, and Slip2000 are also excellent choices. I dont think you can find the one ‘best’ for everything.
I’m a fan of cheap and effective. I mainly use mobile 1 for every gun I own(cars too). I have other lube and solvents but they can be expensive compared to a qt. of motor oil. Then again it’s probably just habit that my grandfather got me started on as a kid.
I use 5W30 just because its what my truck takes and it works great on guns.

Water will dissolve the salts deposited by corrosive ammo. Sliplube 2000 has done well by me and thus far I have not had any issues to report after several classes and thousands of rounds of ammo.
I’m one of those cheap motor oil guys.
I’ve used CLP, then made the move to synthetic Mobil 1, then now use frog lube exclusively.
My problem with the petroleum based stuff is it burning off. The engine oil was more resistant, but I’ve definitely found my niche in frog lube.
Another one for frog lube. Sorry, I know it was not on your list, but do some research and you will see for yourself.
Im a G96 fan personally. Good stuff.
I use weaponshield. Works well for me.
I’m all about saving pennies these days and while I’m sure other oils and grease work great, if I can spend money once for my wrx and use the same oils on my guns why not. It has severed my bcm and ak very well. Also doesn’t dissapate as fast as clp.
Used to use Mobile 1, now I use FrogLube. FireClean sounds interesting though. I may pick some up, but I’m happy with FrogLube. So is the wife when I’m cleaning in the house.
Of the ones you listed, Break Free. The others are too thin and will evaporate quickly. Rem Oil is always on my bench for something quick and dirty, like hitting the exterior surfaces.
I now only use CLP to run a patch thru the C&R guns every few years, but I have a gallon stuck back for TEOTWAWKI. 
We use CLP. Mainly because its cheap and we get it in gallon jugs
I voted “other” for Slip2000EWL. I like it and seems to work a lot better for my long storage guns. However, I still have lots of CLP and I use it on my 22s that I seem to be shooting the most these days. Still love the smell of CLP, but that is purely subjective.
Ballistol or engine oil. No need for more expensive products for me since ballistol or engine oils work.
