Airsoft megastore is shitty. Why would you want large amounts of shitty spring guns anyway?
My list of trusted airsoft suppliers are, AirsoftGI, Evike, and Airsoft Outlet Northwest. Also Airsplat. However that is kinda iffy to me.
When I first started looking into airsoft, I first looked at airsoft megastore. Then I looked around and found they were kind of shitty according to forums and reviews.
