No no no, this is a nade launcher not a paintball gun. 230fps is the 'alterative weapon' limit.

Alrighty I'm lookin to make 2 nade launcher's outta scratch(or close to it) because its cheaper. All need to be kept under 230fps and need to be powered by Cº2 The first I'd like to be a bolt action single shot. It needs to be long to hold the groupings tight and maybe get a little better accuracy. ...
