Can airsoft be played under all temperature/weather
Quick answer is yes with a but. Some batteries don't like it getting too cold and gas guns don't have the power at lower temperatures. Also some gas guns become over powered at higher temperatures. This is just a quick answer.
types of gun/rifle may be recommended for restricted uses under certain weather.
An AEG with a decently large battery is good for all weather. The only problem is some people report the cold (really cold) affecting the life of an upgraded gun.
As for me I use a stock TM M14 with a 8.4v 2400 mah battery and I can play anytime of the year.
