Why Laser Bore sight My Rifle?
The only true standard of a bullet's point-of-impact is the barrel. Laser bore sighting is performed using an in-chamber, bullet-shaped laser pointing device, or a rigid laser device inserted into the barrel end. The laser points at the true point-of-impact using the barrel as a guide. Then, each aiming device is adjusted to the laser pointer at a given distance. 50-75 yards is typical. Much farther and you can't see the laser aim point. Much closer, and the aiming devices crisscross substantially at longer distances. The weapon laser, weapon light, iron sights, red-dot sight and scopes must all be adjusted to match the bore sighting laser.
Keep in mind that bore sighting gets you "on the paper", as in on the target. In order to completely accurize your rifle, you'll need to take it to the range, shoot it at the distance you desire, even with the ammo selection you prefer.
