I decided to pick up an Onslaught today with a properly working siren and much to my surprise the leg panel problem is fixed as well! The pegs on the gray leg panels on mine are longer compared to the first Onslaught I picked up so many months ago. So now the panels don't have the chronic problem of popping out when you look/breathe on it. I forgot to mention that the shield also doesn't pop off easily now. So for those who held off on Onslaught because of these QC issues, you can now buy him but make sure first off that it's one with a properly working siren!
