The AntiVenom Ultra is a heavy duty lubricant for extreme environments and optimized for the most demanding automatic weapon systems. An ionized molecular complex bonds to metallic microstructures, migrates towards friction zones, and withstands high pressures and operating temperatures. Its higher viscosity and film strength serve to increase surface tenacity and boundary thickness. Maximum friction reduction is achieved between -60F and 550F. However, when applied to a weapon recently cleaned with XPLC, ULTRA is capable of temporary performance in environments from -80F to 810F. Like XPLC, ULTRA is hydrophobic, and wood and polymer safe. This model comes in a 4 oz squeeze bottle. Note: This item is not suitable for use as bore cleaner.
