Spare shells for the Smith&Wesson M&P R9 ASG revolver, used to load BB's balls.
The brass shells act as power cartridges into which we load 6mm BB balls. After placing the balls in the shells (1 ball in a shell), the cartridges are loaded into an 8-shot drum. The shells are reusable, but for added convenience it is worth getting an extra set, which greatly speeds up the loading and the level of fun. The set includes 8 shells.
