ABSTRACT:
A weapons simulator in which the rifle barrel is modified as a cylinder provided with a piston designed for movement therein, to provide a recoil effect. The rifle barrel itself serves as the cylinder and the piston is arranged for sliding motion therein, to provide the recoil effect, while actuating a rifle bolt mechanism. An end of the piston is provided with O-rings to seal it against the inside walls of the barrel. A portion of the barrel inside walls is conically shaped, defining a gap which the O-rings do not seal. Travel of the piston end through this barrel portion enables rapid compressed air exhaustion via the gap, simulating recoil. The conically-shaped barrel portion also guides piston re-entry into the cylinder, during a retraction motion of the rifle bolt mechanism.
