Sentry SolutionsHI-SLIP GREASE Synthetic Grease with Screw Top Jar, 2-Ounce by

I ordered this while building an AR recently. It arrived quickly, and I opened it to find it packed absolutely to the rim with smooth, clean grease. Very easy to work with and made the assembly much easier while protecting critical parts. I plan to use it for lubing moving parts on other pieces as well. High quality product, cleans up easily.
