What kind of rifle/caliber is this? See pic inside

Thats a big bullet. Anyone know what this is?

It says 300 BLK, that's 300 Blackout, very similar to the 300 Whisper (221 Fireball case necked to 30 caliber).

Yep, says .300 Blackout on the upper receiver.

I know a guy who has a .300 blk, and a tricked out rifle with suppressor. He bought it specifically for wild pig at 150 (distance from his stand to the feeder) and it just plain works. Those things go down without even knowing what hit them. just plop and a squeal.
