"There are numerous available WEAPONS grease's out there use proper product.These are designed specifically for guns,You don't know what the ingredients in other lubes may do to metal on a molecular level and are asking for a catastrophic failure.This other lube may even remove the current finish on your gun,your not saving any money when you ruin your gun".
On a molecular level eh? Grease consists of very few ingredients when you break it down. Heavy Oil, additives and "Soap". Depending what the additives are comprised eg; Lithium, Molybedendum Disulfide, Calcium. These detergents exist in most oils to react with carbon and bind to it while leaving the Oil clean to do its job. Hi temp wheel and bearing grease usually involves Moly, which has fantastic lubricating properties in of itself. Things which change steel at a molecular level. Heat and Oxygen. Hi temp grease will lubricate at High Temp, as it is designed to do, while eliminating possible heat created by friction, all while the oil in the grease keeps the metal protected at a molecular level from oxygen. If it can run in a bearing in a truck carrying 5000 lbs plus the weight of the truck why wouldn't it keep the 12 ounce bolt carrier in top condition. If you are worried about your finish then don't use known corrosive lubricants like brake fluid. Wheel grease? Go to town! Just because someone in a marketing department saw a guy using bearing grease on his rifle and then pitched it to a company doesn't mean it was redesigned as a grease, just re-labelled. Just because Remington has a can of chlorine free brake-clean with a label on it doesn't mean it is safer or worth 3x more...
