This laser bore sight device offers a safe and effective method for zeroing firearm optics. Emitting a red laser beam between 635–665 nm at under 5mW, the Class 3R laser ensures high visibility while maintaining safety standards. Insert it into the barrel to project the true trajectory line, letting users fine-tune scopes, red dot sights, or iron sights without firing live rounds. Ideal for hunters, competitive shooters, or gunsmiths seeking precision alignment, it’s a cost-effective and efficient calibration tool.
