Laser boresighting devices

[Slater]

To anyone that's used these things, are they all they're cracked up to be?

I've not had the best luck with them.
In my experience, using a laser requires you to be able see the laser on the target as you are botesighting.
I always lost the dot beyond twenty feet. Frustration set it quickly.
I would suppose I had less than ideal conditions, but I've seen the same issues with lasers mounted on pistols.

I have had just as accurate results by simply sandbagging the rifle, removing the bolt, and sighting down the inside of the barrel at a target 25 yards away. Adjust the scope to hit dead center at 25. This method will always get you on on the first shot.

For an AR-15, I just sandbag the upper minus the BCG and do the same thing.

Only rifles this doesn't work for is most semi-autos and lever actions.

I've seen several rifles destroyed by forgetting to remove the laser from the barrel.

I use one for adjusting pistol sights at home and more often than not, they're good at the range.

I have one in the kit, haven't used it in quite a few years, can't remember what brand. It was not calibrated well and pretty much useless beyond 15 yards. I tested it by putting it in a drill chuck and rotated slowly. It made a pretty good circle at 10 feet and beyond.

This. Saves time/ammo

Chambered bore sights are better than the ones you stick in the end of the barrel, also you don't risk nicking the crown of the bore.

They are good for getting you "about there" when you install a scope. I usually zeroed on road sign that was about 100 yards away at night and when I got to the range I was typically 3 to 4 inches off and just fired a 3 shot group and corrected.

This, I ussually get it on a normal sheet of paper at 50yds like this. Center the target in the muzzle, and the muzzle in the chamber, move the dot/crosshair to the bull.

I use a muzzle botesighting device that works really well, it usually gets me within a half inch.
I have used the above mentioned method with great results.
