There are no walk in stores that sell airsoft, with the exception of Calcity Airsoft, in Calgary. A gun will not cost $1000. A gun and all the equipment needed to use and maintain it, as well as gear for playing in, will cost $1000, especially if you need to buy a lot of mags. You can buy from Buyairsoft, but they aren't a very reputable dealer. Unless you get age verified, thats the only site you'll be able to buy from unfortunately.
And its crap.
Not for glory, nor riches, nor honours, but for freedom alone, which no good man gives up except with his life.
