Well, last night I field stipped my M1a for the first time to be certain it was greased and lubed correctly before firing. These are simple rifles! It took me a little while to learn how to remove and reinstall the oprod, but I now know for next time. Anyway, I live a ways from anything, and the only gease I could find was automotive type. So, I went ahead and used it to lube all metal to metal contact areas, and used a light CLP coat on the remainder. Will this auto grease harm anything? The bottle says auto and industrial applications. Thanks.
