Here is another mechanism that is not in Dike. A quarter turn and the handle of removed as well as the shell ejected. It would take but a few seconds to put another cartridge in and pull back on the collar to arm. The trigger is revealed when the collar is cocked. The mechanism is quite complicated and would be a difficult one to make. The same mechanism that attaches the gun to the shaft also attaches a rhino handle to the shaft which makes it lighter for non weapon use.
