Friends! I bring to your attention the concept of Mechanical Zelinka! The very successful Zelinka Form Factor can now be used to mechanically engage a piston with an automatic trigger thanks to the moving barrel! Outside, it will be impossible to recognize where the valve is, and where the mechanical Zelinka is! The use of a ball hook is due to the minimization of the linear size! If the Masters finally do this *Miracle*, then you will be pleasantly surprised by the operation of the gun without throttle and delays! You need to pump through the barrel using the pumping piston! Glory to Ukraine!

Mechanical Zelinka already exists and works well! Master unknown! It differs from my version with a loaded and heavy barrel!
