1. Bushnell Professional Bore Sighter Kit

This is one of the best boresighter kits you can buy, and while Bushnell has been known for making high quality, affordable gun optics, this is one of their best efforts yet. This kit can be used with guns ranging from a .22 to a caliber .45 and comes with a graduated reticle for sighting, plus the design is ideal for a scope that is mounted on typical height rings.

The optic provides HD clarity and the materials used here have been thoroughly tested. Design wise it’s striking and the graduated grid sighting reticle performs admirably. Each graduation is equal to 4 inches at 100 yards and the case is well built. Making adjustments to the scope reticle against the grid to get compensation is easy too.

As far as quality goes the Bushnell is comparable to more expensive laser sighters. One of the reasons why the Bushnell kit has gained a solid following is you can use them indoors, whereas other lasers are only good for the outdoors as they’re too dim. If you’re searching for the best laser bore sight online, this should be on your watchlist as it offers everything you require for accurate rifle sighting.
