Pop Pop Pop, on the third shot, my valve locked open and all my gas emptied. All everyone sees is a big Cadpat guy in the middle of the field, with no primary, and a gas pistol with a huge cloud of white gushing from the slide. At this point, i pulled out my rubber bayonette and charged XD
needless to say it ended painfully for me XD
....and hence forth I have a trusted bolt action. It has never failed me in any weather condition, unless the inner barrel gets to damp from a heavy down pour or really thick fog (resulting in a reduced effect of the hop up on the BB), but this affects AEGs in the same manner. But alas, not many players have the paitents nor skill to utilize a BA effectivly.
The effects of cold weather on all electronics also applies to the batteries. They work fine....they just drain quicker.
The real issue with the cold weather is indeed the resulting damage caused by an upgraded spring slaming the piston head against the front of the mech box. A stock mech box will not survive long with an upgraded spring (higher than 350 fps) in temperatures below -10c, unless you restrict yourself to very limited semi fire only....even then it's not advisable (trust me, you really don't want to have to keep dishing out coin for mech boxes).
On the other hand, a reinforced mech box (such as a Systema 7mm reinforced box) with a stock spring will easily survive short full auto bursts at temperatures down to -18c....for as long as your battery has go go.
But you have to remember that the colder it is, the more brittle the cheap pot metal (which mech boxes are made of) becomes.
Just keep cleaning you airsoft after each game religiously by wiping them down of moisture, removing all sand and dirt, and store them in a dry area free fom humidity, and they'll last a life time. And if you are storing them for any length of time, remove all bateries from add ons such as RDS optics, etc..
As a note; Many years ago we had a noob camp at Flag Raiders. It was held on a weekend in Febuary, with the temperatures bouncing between -10 to -15c (wind chill and so on), and everyone was dressed accordingly. I was a very fun and productive day, but when it was finally done, over eighteen (18) AEG's had bitten the dust because the fronts of the mech boxes had cracked, or broken right off!
Tru suddenly had a large group order, and Gump had too much work....
