DOTM Deluxe Bumblebee's, the first edition one and Cyberfire, weapon is easily modded to lockout into the perfect cannon for Bee, or Deluxe Prime from Wal*Mart. Take your Mechtech weapon and simply, carefully, remove the underside peice from the front of the weapon. It's only on with two little nubs. Now extend the weapon fully, and reattach so the bar in the middle of the peice is behind the barrel. Now the weapon will stay extended out, into an awesome mega cannon for Bumblebee, or Prime.
