I used Tw25b on my pins and the connector areas on the cables.

Tw25b is what we run on the M240B, M249 and the M2 for lubrication. It works like white lithium but when it gets too full of dirt it dries and cracks off like candle wax and it penetrates metal, plus since it'll handle the heat of a crew served weapon going cyclic engine compartment temps (even here) haven't been a problem.
