Well-equipped guy. Don’t know of many .50 cal assault rifles, though.

.50 Beowolf upper or a .50 BMG upper?

Gotta have serious recoil if it was a .50 BMG small enough to conceal under anything sort of a burka!

Probably an AR with a .50 Beowulf upper.

Or a Barrett. ;0), which might be an "assault rifle" in the eyes of a NJ newspaper reporter.

Something like this, maybe. (A single shot .50 AR-15 conversion of some sort.)

I’m thinking it was this.......

It is common to replace the M4 upper with a .50 Beowulf. It is a lengthened .50AE with the head turned down to fit the .223 bolt. 10 of them will single stack in the standard M4-20 round magazine. They are used against vehicles and will take doors off their hinges.
