As much fun as darts, the Stinger Challenge Kit features two (2) P311 Stinger Airsoft repeater pistols that hold up to 12 6mm Airsoft BBs each and shoot at velocities of up to 325 fps. The Airsoft Gel-Trap Target has rings for scoring and the tray at the base catches BBs for easy cleanup. Two packages of 500 count .12-gram Airsoft BBs are included, in two different colors, to make scoring easy. "Be the Game with GameFace"
