Systema PTW Could be working and could not work. When I bought it, it came with one Lipo battery. That battery has since died and puffed up. Can't test it. Hence why im selling cheap and its one of two rifles I have left. Im switching to TM Recoil shocks, so no trades please. It's been Tac modded. I also have 8 brand new MAG 170 round magazines that you will recieve.
