5 Best Laser Bore Sights [Hands-On Tested]

Sighting in a new gun — or re-zeroing an older rifle — can be a very frustrating chore…

It can be such a hassle, in fact, that often, we sometimes end up neglecting that first day at the range for fear of pulling our hair out as we chase shots all over the paper — if we even hit paper from the start.

Traditional bore sighting involves some guesswork.

But now, instead of engaging in a procedure equivalent to tossing darts at a dartboard while looking through a rolled up newspaper, a laser bore sighting system can simplify the whole process for you.

We tested five laser bore sight products — three for general firearm applications, and two specifically for a firearm chambered in .223.

Let’s see how these products performed in the field.

A Note on Testing Procedures

While we performed multiple tests on each product to determine visibility and functionality, we settled on a simple test for comparison’s sake. The goal was to zero a Savage Axis .270 to 100 yards with as few shots as possible.

We started at 25 yards, aligning our first shot using the bore sighters. From there, we would realign and shoot as necessary until we were zeroed at 100 yards.

However, we did something slightly different for the .223 bore sighting products: we wanted to see how the bore sighters would work to set the iron sights at 25 yards.

Safety Note

Remove your bore sight, either in the chamber or on the muzzle of your weapon, BEFORE test firing the firearm. Failing to do so will cause massive damage to your firearm and/or you and/or the people around you.

You would think this didn’t need to be said, but coffee is hot also. Stay safe out there, people!

And just in case, don’t forget to bring your IFAK  to the range with you.

Best General Firearm Bore Sights

1. Bushnell 740100C Laser Boresighter

This is a competent unit, but it lacks power for greater distances and has to be used in a specific way for maximum effectiveness.

The Bushnell can be set up to sight in anything from handguns and rifles to shotguns, and the kit includes arbors to fit from a .22 to a .50 caliber weapon, as well as 12 and 20 gauge shotguns.

Note, however, that this boresight will only work in pistols with barrels 4.5 inches or longer due to its length. Overall, though, the build quality is high, and the all-metal construction feels exceptionally sturdy.

However, the laser did diffuse somewhat quickly, and a special reflective surface was necessary to take full advantage of the Bushnell as we put it through its paces.

Bushnell Laser Boresight

We began our testing in the early morning, with less direct sunlight, and we found this boresighter offered laser visibility to just over 50 yards on a white target. Beyond that range, it was a challenge to see the red spot on the white paper.

This is OK, though, as we began testing at 25 yards, and the Bushnell got us on paper easily.

After fitting the arbor, which took a little adjusting to get the screw seated and the fit correct, the boresighter sat snuggly in the .270’s barrel, and we could easily line up our crosshairs.

The first shot was around 4 minutes of angle off high-left at 25 yards, so we simply readjusted for a second shot at 25 yards without the boresight, and moved out to the 50-yard target distance, where we reinserted the boresighter.

This shot was off by about 5 MOA, but we were on paper, and after a readjustment and two more shots, we zeroed the .270 at 100 yards without using the boresight.

Now, it’s important to remember, the pointer isn’t 100 percent accurate, and it won’t point exactly where your shot goes, but it doesn’t have to do that to get the job done. The idea is to save time and ammo by not having to guess while boresighting.

So, after only two shots lined up with the boresighter, we were set up, and the Bushnell was back in the bag.

Not bad, and the unit is capable overall, as long as you know how to use it. The unit doesn’t feature a super powerful laser, and while it was visible earlier in the day, that visibility dropped significantly over the course of our testing.

It did come with a handy carrying pouch, though, and the system’s versatility is nice.

I can absolutely recommend this product as striking a great balance between price, portability, ease-of-use, wide applicability, and usability, but be aware, you absolutely need a special reflective surface, preferably designed for use with laser boresights, for the Bushnell to be most effective in a variety of conditions.

2. Laserlyte MBS-1 Mini Laser Boresight

This more compact boresighter performed similarly to the Bushnell product, except that it is smaller and can fit into pistols with barrels from 3 inches and above. It lacks arbors that will fit shotgun barrels and is intended for use with rifles and pistol exclusively.

Where the Laserlyte shines — pun intended — is in a slightly more powerful, tighter laser. We could spot the laser more easily past 50 yards, and its beam appeared to be tighter in our testing.

That said, the effective range is close to 65 yards, and certainly no more than 70 yards without a special reflective surface to sight off of. As an aside to both manufacturers, a reflective target insert would be a huge help.

LaserLyte Boresight

When you’re first setting up the Laserlyte — and the Bushnell, for that matter — be aware, the arbors use very small screws that take some finagling to set up properly.

Work over a box or other surface where you won’t have to be concerned about dropping your screws and losing them.

We set the scope on the .270 out of zero and sighted using the Laserlyte. After a single shot at 25 yards, we were only off the expected point of impact by about 2 MOA. This felt a little tighter than the Bushnell Boresighter, but we were still on paper with both systems.

After we shot again at 25 yards and readjusted the scope, we went out to 50 yards and sighted using the boresight to check expected point of impact. The next shot was only about 3 MOA off our aim point, and we were easily able to zero from there.

Boresight Targets

We went out to 100 yards and zeroed easily without using the Laserlyte.

The unit’s greater compactness and slightly more visible laser — especially in more direct sunlight — make the Laserlyte easy to recommend.

The applications between the Bushnell and the Laserlyte are slightly different, and if you’re seeking a boresighter with greater versatility when it comes to pistols, this is probably the unit for you.

Both products performed admirably, however, and both are usable for their intended applications within similar ranges.

3. Wheeler Engineering Professional Boresighter

This unit has a lot of unique, premium features that make it an exceptional product and probably my favorite pick of the bunch.

First, it uses a green laser — every other unit we tested uses a red laser — which was strikingly more visible in daylight, all the way out to 100 yards, without any special reflective materials.

This boresighter also features a strong magnet to attach to the end of a muzzle, and this worked admirably well. However, note that we immediately found the unit did scuff up the rifle crown when first attached it.

Wheeler Boresight (3)

We solved the problem by placing a piece of cleaning cloth in between the crown and the boresight. Arbor-based systems, in theory, may damage the bore upon insertion, so both types of alignment have their pros and cons.

The Wheeler also comes with a lithium battery and a carrying case. Everything about the unit feels premium, and the best part is, it even included a special reflective target sticker that was extremely helpful sighting in every laser boresighter we tested.

I didn’t even have to use the reflective tape I brought because of this. Way to go, Wheeler!

Thumbs up
Thanks, Wheeler!

In terms of our test, the Wheeler wasn’t exactly the most accurate out of the box, probably because of how it attaches to the muzzle. We could rotate the Wheeler on the muzzle, and it absolutely did jump around the paper a bit.

While it took some practice, once we were confident, we took a shot at 25 yards, and we were on paper! Only off by about 3 MOA high and to the right of our aim point.

This was totally acceptable, and after we readjusted our point of aim for a second shot at 25 yards, we moved out to 50 yards and re-sighted using the Wheeler. Our next shot was off around 3 MOA, this time to the bottom-right of our target point.

We adjusted again and were able to zero out at 100 yards. This time, however, because of the powerful laser of the Wheeler, we did use it to check our adjustment, and we were about right on to our point of aim from here.

The Wheeler is an exceptional, premium unit, and it has some excellent features. It’s priced higher than any other unit we tested, however, and it really does have a more limited range of applications in a sense, in that it really isn’t practical for sighting in a pistol.

While you could sight in a shotgun or a pistol with it in theory, I see most users sighting in rifles with the Wheeler.

That said, I highly recommend the Wheeler, especially if want high ease-of-use or you’re sighting in multiple firearms under controlled conditions and want a unit that will save you a lot of time.

For a gunsmith, this might be the unit to have.

For everyone else, an Arbor-based system may be more practical.

.223-Specific In-chamber Bore Sighters

While these two bore sighters are designed for .223 Remington chambers, boresighters that are made for other calibers are widely available. They also all work the same way – just drop them into the chamber like you would a normal cartridge and use per the instructions given.

Be careful when using these and, as always, adhere to the Four Rules of Gun Safety. If you poke around on the internet you can find accountings from people who mistook their live ammo for their bore sight and fired their rifles unexpectedly.

Don’t be that person.

4. Sightmark Laser Boresight

This bore sight is easy to use, and worked reasonably well, though both .223 bore sighters were less powerful than the other units we tested.

The Sightmark takes three AG3 batteries, and was visible only out to about 25 yards, though using the reflective target greatly improved this range. This was fine for the open sights on the rifle we tested. It also comes with a handy carry pouch, which was a nice addition.

Because the Sightmark operates in the chamber and sights down the length of the bore, it proved to be very accurate and extremely easy to use. We simply turned on the laser and loaded the unit, adjusted the sights, and took a shot.

At 25 yards, the Sightmark got us on paper after the first shot, and it only took three more shots to get the open sights adjusted. The accuracy off the bench held true at 50 yards.

We really only had to load the Sightmark once to get on paper, and it performed flawlessly in this application. At greater distances sighting in an optic, however, some reflective material would absolutely be necessary.

5. GoZier Tactical .223 Laser Boresight

The GoZier performed similarly to the Sightmark bore sight. However, the GoZier does take up to four AG3 batters and we found it did appear to be slightly brighter out past 25 yards. I’d say it had an extended range of about 10 to 15 extra yards over the Sightmark.

Practically speaking, however, it didn’t perform substantially better in terms of visibility, and still worked best with a highly reflective surface to sight off of.

After we let our test rifle cool down for a while, the test results were similar. We loaded the laser bore sight after intentionally mis-aligning the rifle’s sights and then sighted the rifle in. We took a single shot, which was on paper, though we were about 2 MOA further from the dead center of our aim point compared to the Sightmark.

GoZier Boresight

This was most likely simply due to the variation in how we had the sights set for the first shot, however, and after we adjusted slightly, we took three more shots.

From there, we were able to fire accurately at 25 yards, and remain on paper and readjust at 50 yards without needing to rechamber the GoZier.

Both the GoZier and Sightmark performed well. The GoZier definitely had a slight but noticeable edge when came to visibility, but both bore sighters needed reflective surfaces to be effective, and both required four shots to sight in the rifle. Both products get my vote.

Final Thoughts

Do you absolutely need a bore sighting product?

Not necessarily

But these units make it so easy to get on paper right from the start and are cheap enough that it seems pointless not to keep at least one of these in your range bag.

Hitting paper the first time you shoot can be invaluable, especially for newbies or those working with multiple firearms. If you’ve ever tried to zero a rifle by sighting down the bore, you’ll know how extremely frustrating it can be if you can’t consistently get on paper right from the start.

A laser bore sight will keep you from chasing your shots all over the paper, saving you time and ammunition in the process.

My favorite for rifles and pistols is the LaserLyte.

    I really don't understand these 'reviews' you guys do... The wheeler is the best? Because why? It's most expensive? You said it's not even that accurate... Isn't that the point of a boresight?? What the hell?

    I have purchased two laser bore sighters, one green and one red, from 2 different makers. Neither centered or zeroed when purchased, The most centered of the two was about 1.25" off which produced a 2.5" circle when rotated. The green laser was adjusted after a lot of trial and error, the red laser is off and not adjustable, rendering it worthless. Neither is visible in daylight at 25 yards. I'm disappointed you didn't address either issue (not with mine but overall) in your reviews. You only mentioned the reflective tape was useful with the Wheeler.

        The case is much more complex than that but the bottom line is that Mcdonald's was at fault for violating local health laws and she was a 70+-year-old grandmother who had 3rd-degree burns to something like 20%+ of her lower body.

    Where does SiteLite rank (especially for AR15/AR9)?

    April 8, 2019 5:52 pm
  • Johnny

    How well does "Wheeler Engineering Professional Boresighter" work and compared to other options with a AR15 muzzle brake? The main concern I have is the muzzle brake has to be squared with the bore, and since the muzzle brake is threaded, it won't be square.

  • ToddC

    Thevp Wheeler is great. It will not stick to stainless. Long muzzle devices give all of them fits. If your barel is threaded a steel thread protector can be you best friend when boresighting.

    I start with a piece of paper with a pure vertical line on it. I tape it to the wall at 5 feet (plumbed vertical). I measure the distance between bore center, and scope tube center. I put two dots on the vertical paper line at the dimensions. I set the rifle on a stand, and put the laser dot (any/all manufacturers) on the lower dot drawn on the line. (usually a regular sharpee dot) and, making sure the rifle is level (line levels, bubble, wally world $1.) I adjust the scope left right to center the cross hair on the upper dot. Left/right adjustments are the most critical to get perfect. I make sure, by scope rotation, that the vertical cross hair aligns perfectly with the plumb vertical line on the paper. It must stay perfect during scope ring screw torquing.
    With left right adjustment being laser perfect, I go to the range, and adjust the vertical poi/poa where I want it.
    The key is consistency, repeatability, and attention to initial set up details.

    Can you use a .223 boresight on a.224 Valkyrie

    October 28, 2018 4:51 pm
    • Jeff

      Yes you can as long as it's one that slips into the muzzle of the barrel. .223, .224 Valkyrie and 22 Nosler are all considered .22 calibers and use the same dia. bullets .224 dia.

      I have a Site Lite SL-150 and can use it for multiple calibers.

      October 28, 2018 5:08 pm
    • David, PPT Editor

      Yes, .223 Remington actually has a bullet diameter of .224 - same as .224 Valk.
