I learned about Slip2000 during an armorer's class for military and LEO's. At the time I was stationed in MT. I had my doubts so I performed my own tests. First the cleaner is amazing and works on everything including cleaning your hands after a day of shooting and then followed by cleaning. Secondly, the EWL lives up to ALL of its claims. Three times we froze an M4 down to -50 degrees F and each time the weapon ran at semi and full auto as if it were running at normal temps. There was zero failures at the BCG showed no signs of slowing like it does with other "high end" lubes. Our other test was to try and burn it off. We ran about 1000 rounds through several rifles on a 101 Degree day without seeing any kind of loss of EWL on the BCG or in the receiver. We then set aside a M4 as a test subject to see how it looked after a year plus of shooting it without re-lubing or cleaning. Aside from some carbon build up, there were no signs of this weapon slowing down...EVER. I now Slip2000's 725, Carbon Killer, Copper Cutter, and EWL on all my precision rifles. I will never look back. Slip2000 is the best stuff for your weapon systems.
