How to sight in a scope with a laser bore sight: step by step

The video above uses the exact laser bore sight we’ve linked to near the top of this article. It’s a great way to follow along with the video and sight your scope. The video will break down what all comes with this particular bore sight model and provides great instructions for anyone needing a visual representation.

Step 1) Safety First

Before you begin any type of maintenance with your gun always make sure to double check that your rifle is empty. Clear the chamber and triple check your rifle and surroundings before attempting to work on your rifle. Don’t let your negligence be the reason yourself or someone else gets harmed. Safety should always be your top priority.

Step 2) Set Up The Adapter

This laser bore sighter comes with 4 different adapters to match the caliber you’re using. Find the adapter you’re going to be using and take the appropriate screw and place it into the back end of the adapter. Use the small Allen wrench to screw the screw into place.

After the screw is in place take it and place it on the end of your bore sighter. The adapter will tighten down on the back end of the adapter to give you the right size fitting for the caliber your rifle uses.

When you place the adapter into your barrel it’ll have two contact points. The end with the adapter will make contact with the inside of the barrel where it’ll sit. Where the boresight increases in size towards the front end this area will make contact with the end of your muzzle.

You can go ahead and place the bore sighter in your rifle.

Now is a good time to determine if you’re going to use the daylight target that came with your bore sight or a standard target. If you’re using the daylight target you’ll point the laser at the center of the target and the squares on the target represent one-inch alignments.

At 100 yards you’ll place the laser light in the center and align your crosshair or red dot to match the boresight. However, if you have less distance you can sight in at 10 yards. If you do this set your sight to the 2″ inch line on the daylight target and this will represent the center if you were at 100 yards for a .22 caliber shot.

Make sure to read the target instructions to see what adjustments you may need depending on your caliber.

Step 3) Find a Stable Position

Using a stable mount or gun vise while sighting your rifle is very important. We recommend using a gun vise that’ll completely hold the rifle in place but you can optionally use the sandbags or secondary stable mount if needed.

Don’t try to rely on your hands or a leaning prop to get the job done. You’ll save yourself a lot of time and headache using a vise. If you don’t have one already we encourage you to save up for one or at the very least try to pick up a low-cost sandbag mount.

Step 4) Aligning Your Sight

With your rifle stable and the laser bore sight in the barrel, you’re ready to align your sight. In the video above the guy does this from the 25-yard range. At this distance, the laser should completely fill up the center of the daylight target included with your boresight.

Counting for bullet rise and drop this will be accurate for 100 yards as demonstrated in the video. The boresight should get you within 3-4″ inches of the center of your target.

When looking through your scope at 25 yards make adjustments where the sight matches up exactly with the red dot from the boresight. This is also an ideal time to line up any backup sights or secondary optics on your rifle.

Once you’re finished please remember to remove your laser bore sight from the barrel of your rifle before shooting. We know this is common sense but mistakes have happened before!
