That appears to be an M-4 equiped with a laser scorer. She could be ready to shoot. After all, she appears to have a reporter in front of her.
THANK YOU VERY MUCH!! :)
Very good. First belly laugh of the day.
It's that, and somewhat more, if by "laser scorer" you mean something like a "MILES" laser. You might have noticed in the video that there is a big cable coming out of the "magazine". The M-4 has been gutted, and really isn't a firearm at all. It's got a pneumatic "kicker" to simulate the recoil. I've "fired" something similar, including one built on an M-240 machine gun, mounted on the top of a simulated "HUMVEE". The driver's sim and the shooters sim were tied together, so as the shooter, you went where the driver drove. The version I "shot" had you wear VR goggles, to display the simulated world. Pretty cool, but the goggles( very early models) were too bulky and interfered with a proper sight picture. Of course you could use the simulated tracers to "aim".
