Winterproofing an AR 10

I'm looking at breakthroughs products anyone use them or anyone have something that they tried didn't like and would get rid of?

It is all very well to read the labels, but it is worth testing lubes by leaving them outside on a cold night and seeing what happens. When I lived North of 60, I would test lubes this way.
There are modern lubricants that perform over extremely wide temperature ranges.
 
Just fyi the mpro 7 clp is rated to -89 f or something like that. I dont mind spray lubes but the bottles go forever and there isn't any waste.... pluss they work if you leave them in the cold lol.

Good idea...simple, easy and will let you know without a doubt if they will work or not!!!
 
10/22 ?
My 10/22 is left at -30 C all weekend hunting ptarmigan for example, without issue, dry.
Drive away by ski-doo on Friday with the 10/22 riding front (chest side) not my back, using a simple sling. Once arrived at camp keep it clear of snow with a soft case, outside. Next morning, take it out of the soft case, cycle it by hand 2-3 times and ready to go hunting. Returning at home, I gradually warm it up with the soft case from frozen to cool to warm temperatures, similar to camera equipments. Clean well, very lightly oil, store it for next time. I religiously use CCI ammo now all year round.
If you know how, consider posting this on the rimfire post page.
 
very cold temps with cause drops in ammo velocity and pressure due to the powder burning slower...these DI systems must suffer from this fact...some powders do lessen this to varying degrees...I would think ammo temp would have a lot to do with reliability...was the ammo in a persons pocket or in the truck a few minutes prior to shooting or was it in the rifle sitting for hours at -40...I'm guessing this can make a VERY big difference in performance....careful loading and powder selection would be a possible way to improve function in very cold temps...I agree that lubes are part of the answer but not 100%

I dont seem to see a difference hot vs cold or even mild 7.62x51 vs hot commercial. 308. as long as the ejector does its job that action is gonna run.... that's the only thing I dont trust the brownells bolt 100% on. In 700+rds I have had 2 failures to eject, probably a chunk of brass stuck in there as the edges are sharp and chew the brass..... time to break out the dremel I guess. Wish I could handle some of the other bcg out there and see who has the best chamfered one. I know some of the 'issued' 308 platforms out there run dual ejectors that are closer to the centerline of the bolt face, would provide much more ejection force for sure.

I am looking at getting a spare bolt head, ideally one that has dual ejectors!!!
 
I wen't through this exact issue last year with my Stag 10. One of the members here recommended G96 "Complete Gun Care" and it has worked flawlessly to -20 C so far, have not had it in colder temps yet. Before that I used dry graphite applied in spray form. Graphite was flawless to -30ish which was the coldest I shot in.

I prefer the G96 as its less messy to apply. Also the rifle sounds like it is lubricated i.e. less metal on metal sound compared to the dry graphite.

Good thought of ammo temperature. All my ammo is at exterior temps while hunting. They are simply in my jacket's exterior pocket while I'm traveling by snowmobile. No pre-heating, no hot pads. Just stable temps for both my ammo and firearm. 😉
 
If your looking for tips and tricks, these are what I've learned over the years.

1. Clean your rifle normally, and lube it. After all said and done, take a clean rag and completely take all the lube off you can by hand without the aide of any solvents. The metal should have oil in the metal but not any oil sitting on the metal. Pay special attention to the;
A. Bolt face
B. Firing pin
C. Trigger mech
D. Cam pin
E. Chamber
F. Bore

2. Once outside, keep it outside. The rifle will sweat when brought back up to temp, and if brought outside again will quickly freeze. When I go hunting once the rifle is out of the vehicle, that is where it will stay until I am done hunting.

3. If you are hunting in cold weather you need to zero your rifle with the ammo you are going to use in cold weather. A good practice is to bring your rifle outside in the cold, load up a few mags, and let it sit for about an hour outside to get everything to the ambient temp outside. Keep in mind
A. Record all cold bore shots. This is the most important
B. Re zero for every 15 degrees in temp change
C. Verify drop for every 100m. Low temps will effect velocity.

4. If the situation permits, in extreme cold. Every hour unload your rifle, and work the action, then reload. This will keep everything from freezing stiff.

Cheers
