yup, from your pic it looks bent to me too but i didnt get to the 4 min mark cos this is a propaganda vid plus i cant believe they were shooting the casings off the bottle while their left hands are holding the mag.
Thats BS.
Every single one I have seen or shot at the range are 4 inches + rifles at 100 yards and this with a good shooter behind. They are no target rifle…stop kidding yourself guys.
