Agreed, it is an AR50.
The OP mistakes it for a bullpup because the shooter is looking through the scope with the bolt open.
I hate to see shooters depicted without eye protection.
Ear protection is obvious, every shot can be heard and it hurts if your ears aren't plugged, so you cover them up and avoid progressive damage.
Eye injury takes place in an instant when something goes wrong, there is no warning, you have to be ready.
