Re: cold weather AR15.
If your AR is reliable at normal temps, then cold weather malfunctions
are probably due to the type of lube that you use. Dry lubes, such
as the Otis Dry and Militech are popular up here. Have known people
to clean and lube with a light coating of diesel. The Army used to use
a product called LSA for warm and LAW for cold weather.
MIL-PRF-14107D: Lubricating oil, Weapons, Low Temperature. This specification covers a preservative lubricating oil for aircraft and ground small arms weapons at temperatures between 0 deg. To –70 deg F (-17.8 deg – 56.6 deg. C). This lubricating oil is identified by military symbol LAW and NATO code # 0-157.
