Mounting a scope is only half the job — getting it properly aligned with your rifle is where things actually start to matter.

A common mistake is heading straight to the range and trying to zero from scratch. Without a reference point, this often turns into a slow and frustrating process, wasting both time and ammunition.

This is where bore sighting comes in.

A bore sighter gives you a visual reference between where your barrel is pointing and where your optic is aimed. Whether you’re using a chamber-style laser or a muzzle-mounted unit, the goal is the same: get your rifle close to zero before you ever fire a shot.

It’s important to understand that bore sighters aren’t precision tools — they’re a starting point. Variations in the device, including slight misalignment in the laser itself, can affect accuracy. A simple way to account for this is to rotate the bore sighter and observe how the point of aim shifts. This helps establish a more reliable center reference before making adjustments.

Taking a few minutes to do this properly can dramatically improve your experience at the range. Instead of chasing your zero, you’ll already be close — making final adjustments quicker, easier, and far more efficient.If you’re regularly mounting optics or switching setups, this is a step worth incorporating into your process.

Here is a video of Stanley and the "See" Can where he goes in depth about how boresights work and how they make your life easier👇
 
Very useful with semis and pumps and anything that isn't a bolt-action rifle where you can simply remove the bolt and visually boresight down the barrel, holding the rifle steady so you can compare what you see there with where the optic crosshairs sit. But honestly even that is a bit of a juggling act compared to simply steering the optic onto the red laser dot!
 
I'm a big fan of the free calibrated zero target from trex arms. Can usually get an on-paper-at-100yd useful zero in three rounds at the indoor 25 yard range, then another 3 rounds for a functional zero when I can get outdoors for a 100yd proof. I have also used boresight lasers with poor-to-moderate success, but I don't find them much of a time or money saver when 6 rounds will do the job. To each his own.
 
I like them
Have the type that slides into the muzzle end
Usually the first shot is close with another 1 or 2 to get on target
Instead of the 3 button batteries it used
i swapped in a Energizer A544 6volt

Used to have the bushnell with the different arbors
Worked good but was bulky and a bit of a performance

Still have a magnetic Leupold one
It works good as well but is a bit finicky
 
Our range has dirt berms that get dusty when dry and there are random rocks showing in the dirt.... If it's dry I will pick out a prominent rock and let one fly and see where the round hits.... if it's close I can move on to the paper but if it's off by more then a foot it's easy to see where the adjustment is needed and I will adjust and repeat until the rock is cracked or scared s h i t less...... :)
