  • The file name for this weapon is "blockar" which refers to "Block Assault Rifle".
  • The B mode model resembles the V-2 Rocket artillery.

  • After changing between the fire modes, some shells can be seen on the ground.
  • In Zombie Modes, a bug is achieveable in B mode where if the user shoots at nearby humans and later gets infected by a zombie, the explosion will kill the humans, thus counting them as frags. This bug also applies to projectile weapons including HE Grenades.
