Pro-Shot ZERO FRICTION Needle Oiler Gun Lube Zero Friction is a fluropolymer lubricant that reduces friction and wear by smoothing and sealing metal. This incrases lubricity between metal surfaces and moving parts and gives excellent performance in either cold or warm weather. The Pro-Shot Zero Friction Needle Oiler is especially handy for lubricating firearms because it penetrates and prevents rust while it lubricates. To quote the experts at Pro-Shot... "Zero Friction’s combination of a premium synthetic base and Extreme Pressure, Anti-Wear, Anti-Oxidants, and Rust Preventative Additives provide Superior smooth performance and Protection on all moving metal parts. Extreme Heat & Cold Multi-Functional Lubrication operating from -75 degrees to over 450 degrees Farenheit." See all of our gun cleaning and maintenance products at our Accessories Page.
