Here's an almost free solution for a tool to decock and recock the bolt that didn't take hours to draw up on the computer or take several more hours to print out multiple revisions on a 3D printer. In fact, any one with a reasonable amount of grey matter between their ears (old school design software) can make something like this in about 10 minutes with a scrap piece of hardwood or laminate and a few common woodworking tools.
