The Sandridge Autococker:
The Sandridge Autococker is the only mass produced iteration of an electronic autococker. It is well thought out and comprehensive, and utilizes some novel ideas to increase the performance of the gun. It is aesthetically pleasing and fairly well engineered. It uses almost entirely off-the-shelf parts to make the gun into a formidable and reliable marker.
