Comes with one pin, one shell, and 3D printed molle holster. I have plenty of 12g CO2 cartridges, but I will not ship them. They’re yours for another $5 if you are picking up locally. Price negotiable, but don’t lowball. Add $5 for shipping. Will trade for WE hi capa 5.1 or WE Glock 18 tight bore inner barrel.
