Preferred lube?
On rails and such, simple lithium grease.
On other parts, Rem lube.
I especially like the grease in my carry gun because it never dries out in the summer time and never drains out of the muzzle end during carry.
I love my Break Free CLP
The thing you must remember about CLP is that it's designed to do a lot of things at once, hence the name, "Cleans-Lubricates-Protects". Anytime a product does all of those things, it doesn't do any of them very well. The Army uses it because a soldier in the field is limited as to what he can carry. By carrying a small amount of one gun care product, it allows him to carry more of the important things he'll need, like ammunition and water. You or I don't have to worry about that. It doesn't effect us if we own 1 product or 10. Therefore having specific products to do specific things is always better. The Army carries MRE's for much the same reason. You wouldn't order one if it was on the menu at Denny's. Bill T.
