I may go to the range tommorrow with my m15 . I have it lubed with breakfree lubricant preservative . The forecast is -29 with the windchill .
For any normal use, weather wont affect much. Where it does make a difference, it's when you fire a few hundred rds, then keep going in the snow, then soak it then fire a few more hundred rds and go on a few days and night.
From my personnal exprerience, with M 16 and other military type weapons the problems only started when exposed to extrem situation such as being expose to heavy snow followed by extreme hight temperature and followed again by extreme cold and snow without opportunities to clean her up. Cold itself is not much a problem. For extreme use, run it completely dry, no oil at all.
