The Sightmark .22 LR Boresight (Sightmark part no. SM39021) chambers in your rimfire rifle like a regular cartridge and projects a red laser dot to show where the bore is aimed. Adjust your sights or scope to the dot and you can start a zero without firing a shot. Sightmark rates it for hunters, competitive shooters and law enforcement who want to cut down on wasted cartridges. A carrying case, batteries and instructions come with it.
