It's frustrating when the sight is way off and you can't even see the impacts on paper, and it costs more ammo and time to get it right.
In this quick instructional guide, let's discuss how to zero a red dot at home without actually fire a single shot, so you spend more time shooting on the range and only a little time refining the zero.
Let's check it out
Note: This is a rough zero to get as close as possible, live fire is still required to fine tune the zero for different barrel length and ammo type.

2 Ways To Zero Your Sights Without Live Fire
Laser Boresight - The Fastest Way
Move the reticle in the ball park range of the laser pointer!
Always confirm and fine tune with live ammo later.
Different barrel length & ammo type yield different results.
Do not assume laser point of aim is actual bullet's point of impact.
Why use this method for red dot zero - Using a laser boresight is by far the fastest way to zero a red dot sight roughly to the trajectory of the bullet from barrel. The laser device is built into the shape of a bullet that fits inside the gun chamber, and they are available for various calibers.
Please note that the bullet's flight path will not exactly match the laser pointer. In fact, once your optic has been zeroed with live ammo, the laser and the reticle shouldn't overlap, and that's a good sign.
Saves Ammo - Minimizes ammo usage when a sight is way off course
Works For Offset Red Dot - Quickly zero an offset red dot at a tilt angle and establish a good POA / POI offset
