Home Forums Hunting & Shooting Hunting Optics Please Explain Laser Bore Sighter

It doesn't really need to be square with the world, only square with you when you shoulder it.

Which makes the whole business of locking it up tight in a vise moot, right? And - how does one go about leveling it while holding the rifle? (And then there is the whole matter of the Weaver rings.) Not meaning to be flippant, really trying to get a handle on this - thanks for your comment.

Ideally you want it square to the rifle, with the bottom of the vertical crosshair pointing at the center of the rifle bore. Then when shooting, you want the horizontal crosshair level. Otherwise when you sight in you'll be introducing a horizontal correction that will produce windage error at other distances.

The laser boresighter is great for getting solid info on a rifle/scope indoors and quickly. It can be used for gross adjustments. Folks come over to my house fairly regularly with rifles in tow wondering what to do next, and the boresighter appears soon after.

They can also be used with airsoft gadgets. The tough part about sighting through the bore is keeping the rifle immobile. A cheap laser boresighter will give good intel from anywhere in any lighting. For example, upon arrival at hunting camp after dark when it won't be possible to look down the bore or shoot confirmation rounds. It wasn't intended to take a rifle from out-of-box to hunt ready without fine tuning.
