Abstract: A firearm simulation system for enhanced firearms training comprises at least one weapon with a mechanically activated laser. The system includes a normally closed laser activation circuit used in conjunction with a recoil kit. The normally closed laser activation circuit comprises a conductive seal, a ball bearing, and a recoil spring. The recoil spring presses or urges the ball bearing into contact with the conductive seal. The function of the laser activation circuit is mechanically triggered and the laser activation circuit is electrically connected to a light source (e.g., a laser light) and configured to activate the light source, simulating a projectile being fired from a weapon. When the trigger of the simulated weapon is pulled, a striker pin dislodges the ball bearing, moving it out of its original position is contact with the conductive seal. The displacement of the ball bearing by the striker pin, away from the conductive seal, creates an open circuit.
