Totally agree. Most people don't realize that grease comes in different viscosities just like oil does. Just about anything you can commonly buy at the WalMart or auto parts house is NLGI #2 wheel bearing grease. They are mostly too thick for use on guns except for M1 Garands and the M14/M1A which require it. NLGI #1 or #0 grease is much better being very soft to semi fluid but you have to hunt for those. They work much better on firearms. I've been using a light synthetic grease on all my autos for awhile now including all lube points on my AR with great results. My new hotness is Redline assembly lube but the grease that Liberty lubricants sells works pretty well too. Don't tump over the can on the Redline, it'll spill all over your bench. Doesn't get really cold where I'm at as long as we exclude last month. It's definitely synthetic oil or even dry for really cold conditions.
