Mach Sakai presents the Laser Barrel training system from Meiwa Logic System, an airsoft gun accessory that enables target shooting practice without firing BBs. The system operates by replacing the inner barrel of a gas blowback airsoft pistol with a specialized barrel. When the airsoft gun is fired, the force of the gas blowback activates a laser projected through the barrel, which functions as a simulated projectile.

To use the system, users print a free paper target and film it using a companion smartphone application. The app tracks the laser's impact point on the target, providing immediate visual feedback on shot placement.
