Jag Arms M870 scattergun that has been CONVERTED (not tapped) to HPA. Included is a 3d printed m4 mag adaptor, and a red dot site. NOTE: There is a jam existing in the shotgun right now. A bb is jamming the pump action and not allowing it to pump. If I had the time, id clear it. But I do not. Once that is cleared, it will work perfectly. NO TRADES! Paypal Only!
