Hello Lawn Gnome to answer your questions I am just a "gentleman of a certain age" who has had the pleasure of seeing the Canadian Forces go from WW2/Korea War vintage small arms (C1/C1 SMG/C2/C5)to the weapons fielded today. No autographed bibles, sorry. Personally for me I kept my rifle clean and dry in winter. If its so cold the damn things not going to rust, and its (the C7) capable of working just fine while bone dry. Sure firing a dry weapon while accelarate its wear/service life but thats really of little concern.
Anyone with experience using SLiP 2000 Gun Lube at very low temps? It is claimed to "withstand extreme temperature changes (-110°F to +1250°F)".
I have used it at more or less normal (for eastern Canada) temperatures and found it to be a great lube and corrosion preventer. I will not go back to using CLP.

VVL-800 is the spec for long term preservative oilfor small arms. It is horrible stuff (read the MSDS). The guys applying it have to wear great big gloves and I've seen guys with bad skin reactions. Makes breakfree feel like skin cream. I wouldn't use it for lube, but if I was burying guns for zombie time...
The current CF arctic oil is going to be replaced.
I can't find anything that works better - and it's Canadian! It has fantastic corrosion resistance and works across a wide range of temps. I have seen it work at 70 below and run flawlessly (a C7 or C8 will not run in EXTREME cold if it is dry) and I have seen it run for over 6K rounds.
The NSN is 9150-20-001-7107 but that's for 4 L jugs.
You must have been on the BMQ on the range next to me that day? I was shooting 9mm that day part of the DP2A. Terrible weather, LOL.

On the one and only range qualification that I will ever admit to hating, it was lovely Shilo at minus stupid (it was so cold, we had to warm the patches for the targets with our hands for them to stick to the paper) - the C7 worked just fine, can't say so much for my fingers.
As far as I know, we just used CLP.

I just looked it up, WD40 has a pour point of -63`C maybe this would be alright or else say to hell with it and just run it dry. The reason I looked up WD40 is it is a common lube available everywhere, and I live in the country.
Hahaha, on this DP2 shoot the targets were covered in a thin layer of ice, and putting the patches on to cover the holes was impossible, they just slipped off and blew away. There was no way of knowing the scores and when "best shot" was awarded to the one guy who claimed he shot a perfect score, the entire course was laughing since there was no way of knowing

I can't see why not. The lowest viscosity synthetic you can find. Just use it sparingly. IMO the worst thing about the C7 in winter was the POS C79 elcan sight always fogging, frosting or having snow on it. That rifle should wear irons in the winter, it's impossible to keep a scope clear doing section attacks on snowshoes.
The C7A2 comes with a decent set of iron sites issued with the weapon, you can remove the POS C79 and use them instead.

CLP or Arctic oil is fine for any weather the shooter can be effective in. Clean the parts as normal and ensure you wipe off all excess oil on the surface of the metal. Condensation and melting snow, freezing rain, etc on the gun will eventually get into your action if you are shooting and then letting it freeze in cycles so the operator should cycle the action periodically to break the action free from freeze up. Do the drill as you would a press check every time you have the opportunity to ensure its not frozen when needed.
Graphite is not recommended for use by Colt Canada for C7/C8 FOW despite units sometimes buying it locally purchased and using it. Take that FWIW for all other AR family of weapons.
In freezing rain and blowing snow the issued C79 scope cover is your friend. Yes, its slower to get into action but its better than not having optics at all. Have an absorbent lens cloth warm, dry, and handy if you use any optic in bad weather. If you are using an issued C79 scope, switching back and forth to irons is not realistic every time the weather gets bad. The whole platoon (or whatever group) switching to irons in the winter and losing the benefits of optics for target ID etc is not an option. Train in the snow and cold more with your equipment and work through the problem. If Canadian troops can't fight in the snow who can?
