There are a ton of lubricants out there for firearms that have made major leaps forward from M-Pro7 to Frog Lube to Slip 2000.  I still have ancient remnants of gun cleaning supplies sitting in my reloading room that are probable going to end up in the hands of my grandchildren if I don’t conjure up the courage to thrown them out, but I’ve used Rem Oil and a few other items in those piles to fix door knobs and swivels on cabinets and it seems a waste to just chuck it.   I have however given up on using anything but M-Pro 7 and Slip 2000 on my firearms because I’ve pretty much found what I’ve been looking for.   There are always slight pros and cons between M-Pro 7, Frog Lube and Slip 2000 but I don’t notice the difference.   Chemical engineering and synthetic oils have crossed over from car oils to gun oils and I actually have a few friends that use Mobil 1 on their guns although that does not have the preservatives that Slip 2000 or some of the other weapon lubricants have.

I have used the Slip 2000 EWL on all of my AR15 and also my AK rifles and even after using the rifles for hundreds of rounds the bolt carrier group still looks wet.   Sure if you heat the gun up in a firefight the lube is going to burn off at a higher rate but Slip 2000 EWL has a good reputation from some of our Special Ops customers that in all honesty, was the recommendation for us to carrier the product line.  I am going to work on some of the Copper Removers and see what I notice but I have never really felt the need to have to have this done on the combat rifles I own due to the fact that I never notice any deterioration in the accuracy as of yet.   For handguns and bolt action rifles you can use the Slip 2000 EWL but If  you look at the technical specs on it, it’s probable a bit of an over kill and you best save that for your FAL, AK, Steyr Aug, G3 or other military style rifle.   The Slip 2000 gun lube is probable best for handguns, bolt actions and revolvers.
