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.

[ I claim:] [1.] A recoil simulator for a weapon comprising:a rifle barrel having a sealing plug disposed therein proximate an exit end thereof, said barrel being formed with an inlet opening behind said plug for entry of compressed air therein; anda piston rod and cylinder arranged for sliding motion one with respect to the other, a gap being developed therebetween during a portion of said sliding motion, said cylinder being in fluid communication with said barrel inlet opening, said sliding motion being arranged to actuate a rifle bolt firing mechanism,such that when said compressed air is directed to flow within said rifle barrel, said piston and cylinder sliding motion simulates a rifle bolt firing action, and rapid release of said compressed air via said piston and cylinder gap simulates recoil. [13.] A method of operating a recoil simulator for a weapon comprising the steps of:providing a rifle barrel having a sealing plug disposed therein proximate an exit end thereof, said barrel being formed with an inlet opening behind said plug for entry of compressed air therein;providing a piston rod and cylinder arranged for sliding motion one with respect to the other, a gap being developed therebetween during a portion of said sliding motion, said cylinder being in fluid communication with said barrel inlet opening, said sliding motion being arranged to actuate a rifle bolt firing mechanism; anddirecting compressed air to flow within said rifle barrel, such that said piston and cylinder sliding motion simulates a rifle bolt firing action, and rapid release of said compressed air via said piston and cylinder gap simulates recoil. The method of claim 13 wherein a portion of said rifle barrel is modified to increase its diameter, said modified barrel portion constituting said cylinder. The method of claim 14 wherein said piston rod is arranged for sliding motion within said cylinder which is fixed. The method of claim 13 wherein said rifle bolt firing mechanism is modified to provide said cylinder. The method of claim 16 wherein said cylinder is arranged for sliding motion on said piston rod which is fixed. The method of claim 13 further comprising a gas barrel cylinder in fluid communication with said rifle barrel. The method of claim 18 wherein said piston rod is arranged for sliding motion within said gas barrel cylinder which is fixed.
