I wanted to start a discussion on using the AR platform in extreme or just plain cold weather. I recently took my ar into the mountains when it was snowing and about 20 degrees. the rifle gave me some feeding issues, not feeding rounds after firing. After reading some online there are some cold weather specific lubes but even with those the trick seems to be to use it very sparingly, the opposite of most conditions to the ar, they like to run wet in most cases. so tonight I pulled out my rifle and wiped everything down with a dry clean cloth so that ther is a thin layer of lube on all the parts. not dry but almost. it actually cycles smoothly manually. my goal is to head up into the mnts on sunday, its supposed to snow on and off this weekend so we'll see what the weathers like. but I want to try it again in the cold with very little lube on the rifle and see how it goes. Last time it it was impossible to prevent snow from getting in the rifles action, if the dust cover was open a second some flakes go on it. worst was when the bolt locked back on the last round. this allowed even just a few flakes to get into the chamber and bolt. water + oil + cold = bad for ar rifle. the water and oil mix and freeze which binds up and slows down the action. please share experiences and remedies.
