I designed the Bear Creek Arsenal BC-9 rear buffer device for their bufferless AR-9 uppers. I did this so I could model it in the bullpup lower I'm working on. I modeled everything except the inside of the QD mount, and the threads in the back of buffer since I don't have pitch gauge. The included Step file has both the buffer tube, and the rear attachment modeled as 2 separate bodies.
