Lube is needed, regardless of what miracle parts and coatings.
I have seen more issues at low temps and in sandy climates because of the lack of lubricants, than from any other thing save bad mags.

As to low temp ammo, look for single base powders. They are the most temperature stable historically.

I will echo this. When doing cold weather training CLP kept in your inner pocket and the forward assist was our best friend. After the 1st *CYCLED* round the weapon system was warm enough to fire without issue. Just getting that first round to *CYCLE AND* fire was the hard part when everything was frozen.
