View Full Version : AR-15 and coldness?

December 29, 2010, 05:37 PM
Hey all! So couple months ago I purchased a DPMS AR-15 just for varmint/plinking purposes and out here in the boonies guns kind of just lay around the house...We do have a gun safe that holds 24 but that is full right now and we have about 6 guns that sit around the house in corners. So...my concern is that, the room it is currently being "stored" in is usually on the colder end(probably about 50-60 degrees, very old house and huge open fields for cold drifts!), granted the rest of the house is warm but the AR-15 cant be stored in those rooms. Will keeping this rifle in that temperature affect it at all? Responses and thank you!

Cold and dry is good storage conditions. If there is any humidity you will start seeing rust on the steel parts.

If the room gets to 300 degrees below zero then you will have effectively cryo-treated it and improved it's overall quality. But anything else will just make it cold to the touch.;)

you might try a soft case or even cover it with an old blanket if nothing else.I keep a 12ga. in the corner by the bed with an old small blanket over it. If nothing else it will keep the dust off of it.

Like others have said... cold and dry = good. Wrapping in blankets might trap in moisture and condensation in the event of a temperature shift. If you wanted it covered they sell those silicone treated gun socks for that purpose.

Wrapping it up is a horrible idea. :rolleyes: I stored a 10/22 in a cold room in a soft case once and pitted the heck out of the outside of the barrel. Wrapping a gun in a soft cover only traps moisture.

Cold won't hurt an AR. The only cold weather warnings for AR/M16 is when you come in from out in the cold. You don't want to rapid warm the gun by entering a warm room. Condensation will occur and could cause corrosion in exposed metal surfaces.

What will effect it more is taking it from warm to cold. It sweats then can freeze. As far as keeping them in the cold wont hurt them.

I keep several in the shop which isn't heated until I build a fire. I can a porthole or window that I often shoot out of in bad weather. Even below zero I have no problems. 50-60 degrees isn't gonna hurt anything.

Having said that, cold ammo will be effected. For example, if I build a fire in my shop, and start shooting as it (and the ammo) warms up, you can see a difference in impact. The average is about 1 MOA per 15 degrees change in temp. But thats an extended shooting period you see that.

Are we talking about women or guns...got lost there for a minute. :p

You won't have a storage issue due to temp.

the gun in my corner with an old blanket over it has never rusted or gotten wet. its inside my house not out in the shed. i cover it up to keep dust off of it. its not wrapped up just sitting there waiting on a bad guy with an old blanket over it.come on people.

From cold to warm will cause the condensation I think as long as you rub it down once in a while with a little lube.

I wish that I had a gun cabinet filled to capacity and more in the corners, poor you.

At my place 4 or 5 rifles stay out in the cold all winter. One each in a tractor, atv, 2 pickups, and in a toolbox in the barn. Cold won't cause a problem unless you overlube and it's really cold. It's changing temps that causes problems with condensation. We had a heatwave today and the tractors are dripping inside the barn. It's a big concern but not much can be done except warm them up well later and cook the moisture out of the gears and hydraulic lines.
