I've been using DSX lubricants for 7+ years with great results. For $10.95 I bought the range bag "gun kit". A tub of DSX grease,a spray bottle of "STEALTH", a spray bottle of oil, & a treated gun wipe. I dilute the grease with RIG sometimes. The oil I use on the rails and the end of my barrel. The STEALTH is a quick drying lubricant which I use on my HK's and AR's. The STEALTH doesn't absorb or attract grit and dirt on the bolts. My rifles have never failed!! Springfield Armory uses in in the assembly of the FBI model .45's and for lubrication. Police depts, FBI Swat team members, and several SEAL Teams use the DSX lubricants too. If anyone is intersted in a brochure or information on this great stuff, ask for Mike at 703-860-0286 or toll free 1-800-822-0258. He's always been giving of his time to me and is quite knowledgable of the product. He's also an avid 1911 shooter. I bet you'll be impressed...........Keith
