Spider Paintball guns have quite a few different gun s in which they are automatic and semi-automatic.  Some guns that they have are the shutter, E-99, and the compact.  Spiders can not have a flat line on it they have options but not everyone like some other gun brands/companies.  I currently have a spider E-99 which can be semiautomatic and also automatic.  I enjoy this gun very much.  I have a lot of fun with my paintball gun.
