Works with scopes, holographic red dot sights, and variety sights.
Durable, machined brass housing looks like a cartridge case but actually contains the entire laser system and batteries.
Insert the batteries and screw the cap on the housing to turn on the laser; remove the batteries to turn off.
Insert the entire assembly into the chamber, gently close the action, and aim at a target 20-30 yards away. Adjust windage and elevation of the scope or sights so point-of-aim is zeroed on.
