What is the best boresighter in 2023?
The lineup we have here includes three bore sighters, each one using a different mechanism for bore sighting.
The Okeba Collimator is a very functional tool in its category. However, the more modern bore sighting methods, such as laser and magnetic bore sights, may get the upper hand in terms of ease of use.
The Sightmark is caliber-specific, though; so if you have several calibers, you’d need other good bore sights.
Sightmark has a universal version, and you may consider that, too. It sells around the same price range.
