I live in central New York and it has been bitter cold this winter. I went shooting last weekend, it was 0° out and -10° windchill. I fired some rounds through my AR-15 which has been treated with Froglube and then threw the rifle into a pile of snow and let it freeze up for a good half hour. I then went to fire the it and it shot great. Wasn’t sluggish, didn’t jam or have any issues at all. I read some reviews about Froglube not working well in the cold but I had zero issues. I was also running the bolt wet just to try to make it fail but it wouldn’t. Oh and cleanup was so much easier!
