*****Still a work in progress. This is what I have got working reliably with a bolt weight and the trip that I included in pack. Also included a pseudo LRBHO follower for Scarpion magazines that has been working for me. Some fitting and tweaking might be needed depending on print settings (it worked right off printed for me). If you try this lower please print and use at your own risk. Bolt bounce can lead to dangerous situations and cause of injury. Regular velocity and high velocity rounds are recommended but should be able to be tuned for subs. I need more range time. If I had more access to a range I could have put this together better. For now I have my SS Scarpion so I think I am going to be done with this project. Anybody that wants to do more please do. Anything I do is open source and for the community to work upon and improve. I am very unskilled at CAD but trying.
