it's that delrin (whatever) plastic bolt. Got it from Vmempire store. Don't know where to get the aluminum one. And it fits in the hole but it needs to be pushed to move through. So should it be able to slide through by gravity alone or no? Oh and you'll be glad to hear I am not going to drill out the internal EC. Instead I am going to make a small external one that will screw into the ASA, with both bottles off the gun it will make it light enough, plus the lightened hammer. As for screwing out the stock bolt, I'd rather not, I don't have a spare
