I have been using FrogLube for 2 years on dozens of firearms and I have tested it in extreme cold with no ill effects. I've got plenty so I'll pass on the give away. Great product.
I use frog lube religiously on all my firearms. My Springfield XD's work perfectly and show no sign of sluggishness. I swear my AR cycles smoother after cleaning and lubing it the 3rd time with FrogLube! And for the bonus...my wife will let me clean them IN the house now!
