MC2500 Oil 2oz.  MC2500® Oil is engineered with the same chemistry that distinguishes TW25B® -- but it’s specially formulated in a lighter “oil” viscosity. MC2500® delivers the same exceptional performance that TW25B® grease is known for. Its lighter viscosity allows for easy migration to hard-to-reach weapon parts, such as trigger assemblies. Ideal for dispensing into parts where a full disassembly is neither desirable nor practical. Also excellent for general quick-lubrication replenishment to all parts. All synthetic, non-toxic.  This is a great lubricant/protectant for Biathlon use as it retains consistent viscosity through a huge temperature range, including well below minimum race temperature of -20C.  Made in USA.
