And what lube were you using? I read the thread and if I missed it I apologize.

The lube gummed up, and I was getting light firing pin strikes. I heated up the BCG, taking 90% of the lube off. After that it ran flawlessly.
The next time out, when the temps get to 10 below or colder, I will give it a go with a super low viscosity oil.
It is 6 degrees currently. Not cold enough.
I remember reading a training bulletin back in the early nineties regarding the M16's propensity to go "bang-click" in very cold weather. The bulletin said to use LAW (Light Arctic Weapon lube?) instead of CLP.
I also remember my fist night in the field in Basic back in the eighties. Our canteens froze. I have hated the cold ever since. But keep this info coming please so we can stay current.
