I just wanted to show a pic of my newly armed Frenzy (Rumble to get the same when he arrives). Piledrivers and guns from the PE Frenzy/Rumble. The piledrivers attach to the arm via the piledriver peg and a hole I drilled. The guns attach to the piledrivers via another drilled hole. To give the guns on back appearance. The guns/pistols can be held in the robots hand as well - Hasbro's policy of putting fist holes on legends. Fits without modding.
