This guide explains how a bore sighter works to initially align a red dot sight with a firearm's bore. By projecting a laser along the bore's path, it allows for a preliminary zero at a chosen distance, significantly reducing the need for extensive live-fire adjustments. The SiteRight 2.0 from Tactical Elites is demonstrated on a P365 Flux Raider, highlighting the concept of height over bore.

Quick Summary

A bore sighter works by inserting into your firearm's bore and projecting a laser along its axis. This laser line represents the bullet's trajectory, allowing you to align your red dot sight's aiming point with it at a chosen distance, simplifying the zeroing process and accounting for height over bore.

Frequently Asked Questions

How does a bore sighter help zero a red dot sight?

A bore sighter inserts into your firearm's bore and projects a laser along its axis. This laser shows the bullet's path, allowing you to align your red dot sight's aiming point with it at a desired distance, significantly simplifying the zeroing process.

What is 'height over bore' in firearms?

Height over bore is the vertical distance between the center of your firearm's barrel and the center of your optic's aiming point. This difference means your sight picture and the bullet's actual impact point will diverge at different ranges.

What is the purpose of zeroing a red dot sight?

Zeroing a red dot sight ensures that where you aim (the red dot) corresponds to where the bullet will hit at a specific distance. This is crucial for accurate shooting, especially in tactical or hunting scenarios.

Can I use a bore sighter for any firearm?

Yes, bore sighters are generally designed to fit various firearm calibers. You typically need to ensure you have the correct adapter or insert for your specific firearm's bore diameter.
