This refers to a firearm, visually resembling a Kalashnikov rifle, modified to fire blank cartridges in a fully automatic mode. These devices are designed to produce realistic sound and visual effects, simulating live gunfire, without discharging actual projectiles. A common application is in theatrical productions and film making.
The value of these devices lies in their ability to create immersive experiences in entertainment and training scenarios. They offer a safer alternative to live firearms for simulating combat or dramatic scenes. Historically, their use has allowed for greater realism in historical reenactments and military training exercises while minimizing the risk of injury or accidental discharge. This also significantly reduces the requirements for specialized safety and control on set.
