Advanced Lubrication System for precision and recreational weapons. Gun Snot was invented and trademarked for the 2004 Olympics and Matt Emmons (multi-time winner) a supporter of the lube at the time. It has only been sold to precision shooters and pro shooting programs since then. This is a distributor product and Gun Snot LLC will not sell too retail with handsome margins to support distributor efforts. 5 different products and some auxiliary items to help with the application to the weapon. Simple use and a serious pre-lube cleaning to degrease and remove the old lubes and waxes first. (less)
