Anyone know what that rifle she's using is? I want to say it's a short carbine HK M416, but the attachments make me think it's something from MagPul.
Well the negative space system she is using is M-Lok, the lower seems H&K built, but lots of aftermarket receivers now have the square magwell and the H&K fire selector markings. Realistically, it could be any mfg. While departments are supposed to only have approved brands in inventory, the reality is due to be strapped for cash, anything that comes into the departments hands (even that which was formally evidence or a buyback and no longer needed) could be worked on by an armorer and passed on to an officer's hands.
