LASER BORESIGHTER Reviews & Ratings

Easy-to-use, self-contained boresighting system fits in the chamber of your rifle or pistol and projects a powerful red laser beam aligned with the bore axis for sighting to the point-of-aim without firing a shot. Works with scopes, holographic red dot sights, and “iron” sights. Durable, machined brass housing looks like a cartridge case but actually contains the entire laser system and batteries. Insert the batteries and screw the cap on the housing to turn on the laser; remove the batteries to turn off. Insert the entire assembly into the chamber, gently close the action, and aim at a target 20-30 yards away. Adjust windage and elevation of the scope or sights so point-of-aim is zeroed on the dot, compensating for sight offset to prevent gun from shooting high. Go to the range for test shots and final sight adjustments. Store boresighter in the included nylon carrying case that fits easily in a pocket, tool kit, or range bag. Available in a variety of calibers, listed below.

Building my tool stock

This is the second .30 bore sighter I've purchased, and the first in chamber laser. I have yet to test it out, so this is a preliminary review.

Boresighter test

Noticing a negative review of a Sightmark boresighter (for a .40 Glock) I decided to test my own .45 Sightmark to see if the beam was in alignment with the case (and barrel). I marked an index on the rear of the case and set it in a sturdy cradle with the index at the 0000-position and projected it at an indoor target 18 ft away, and marked the spot. I then rotated the boresighter index to the 0300-position and marked the spot. Thence, the 0600- and 0900-positions. The average deviation from the center of the pattern was 1/8", indicating a possible error of 0.033-degrees of arc. At HD ranges, that is probably acceptable, but I would recommend buyers do their own tests and return the piece if the results are not acceptable for the required use. I agree with others that the original batteries are not too robust, and premium batteries are in order as the laser's draw is significant.
