LaserLyte Laser Cartridge Trainer Features The LaserLyte Laser Cartridge Trainer is built in a brass cartridge format sized for .223 Remington and 5.56 NATO chambers dropping into the chamber without damaging the rifle and aligning precisely with the bore for consistent results. Two swappable end caps give the cartridge its dual purpose design letting one product serve as both a dry fire trainer and a bore sighting tool. The laser trainer cap is firing pin activated emitting a visible Class 3A red laser at 650 nanometers for a split second every time the trigger is pulled showing exactly where the shot would have landed. This cap is compatible with all LaserLyte electronic targets supporting structured dry fire drills at home without live ammunition. Swap to the bore sight end cap and the laser switches to a constant-on beam allowing quick and accurate sight-in of scopes red dots iron sights or laser sights without a trip to the range. Batteries are included with the cartridge so it is ready to use right out of the package. Running on standard batteries good for up to 3 000 shots the trainer offers extended use before any battery replacement is needed.
