Sightmark SM39024 Triple Duty Universal Red Laser Boresight .17-.50 Cal

The Sightmark SM39024 Triple Duty Universal Boresight delivers precision laser bore sighting across the widest caliber range available in a single device. This red laser boresight eliminates the guesswork from initial scope mounting and rifle zeroing, saving ammunition and range time while ensuring accurate shot placement from the first round.

What Makes This Different

Unlike single-caliber boresights that require multiple purchases, the SM39024 covers everything from .17 HMR to .50 caliber rifles through its comprehensive arbor system. The precision-machined components maintain consistent alignment across all supported calibers, while the high-visibility red laser provides clear reference points at extended distances. This universal compatibility makes it the only boresight most shooters will ever need.
