Sightmark SM39019 .44 Magnum Red Laser Boresight with Battery Case

The Sightmark SM39019 red laser boresight eliminates guesswork when zeroing .44 Magnum firearms, saving ammunition and range time. This precision tool projects a bright red laser dot that shows exactly where the barrel points, allowing shooters to align optics before firing their first shot.

What Makes This Different

Unlike generic boresights that require constant battery replacement, the SM39019 includes a dedicated battery pack for extended use sessions. The brass construction matches the exact dimensions of .44 Magnum cartridges, ensuring proper chamber fit without the play common in plastic alternatives. The included carrying case protects the precision components during transport and storage.

Key Features

• Class IIIA red laser provides visibility up to 100 yards in daylight conditions

Range testing becomes more efficient as shooters can establish initial zero without firing expensive .44 Magnum ammunition. The bright red dot remains visible against most target backgrounds, making scope adjustments straightforward even in moderate lighting. Hunters appreciate the ability to verify zero after transport, while competitive shooters use it for quick sight confirmation between stages.
