HELL YEAH, THEY SAID BIG EFFING GUN!
Stop looking so shocked JB. Yes, it's bigger than yours.
So, grenade launcher, giant camera or ~alien weaponry~? WAIT, WHAT??? I'M SORRY, I CAN'T HEAR YOUR ANSWER OVER THE SOUND OF HOW AWESOME THIS IS.
There are even more pics (some new, most the same as yesterday's) at
the *unofficial* JB website (source).
