How to Boresight and Stop Wasting AR-15 Ammo

Accudot Laser Boresights
Boresighting is a reliable way to align your sights or optic’s reticle with the bore.

As anxious as we all are to get out to the range with a new optic for our AR, to eliminate frustration, we must spend time and money sighting it in. No red dot, scope or laser comes with pinpoint accuracy right out of the box. There is just too much variation for that to be possible. So, since we invest in optics to help us be more accurate, it’s important to make sure it works correctly. Whether it be having one chance to hit that monstrous pig, or your life is in imminent danger, you want the confidence knowing your bullet is going to hit where you aim.

That’s why we take the time and waste the ammo to sighting in our optics to get them exact. However, there is a way to cut down your costs, save time and start hitting the bullseye faster. With Sightmark’s improved Accudot laser boresight design, you’ll be punching holes in holes before you know it—all without initially using any ammo or paying for range time!

No one wants to waste ammo (money!) just trying to hit somewhere on the paper, right?

What is Boresighting?

Boresighting is a method of adjustment to a firearm sight or optic to align the firearm barrel and sights. The goal of boresighting is to get on paper. it is a reliable way to align your sights or optic’s reticle with the true center of the barrel (the bore.)

Accudot Laser Boresights


Sightmark’s Accudot laser in-chamber boresights allow you to get to zero faster by projecting a laser onto a target, making it easier to align your reticle, sights or red dot with the rifle’s bore. Even before your first shot, the Accudot boresight gets you sighted in faster with point-of-impact and point-of-aim identification.

The Sightmark Accudot in-chamber laser boresight’s precise design inherently makes it more accurate than boresights on the market. Constructed of thick-walled, precision-machined brass, Accudot caliber-specific laser boresights employ a calibrated Class IIIa laser diode and bullet tip for improved chamber fit, precise centering, as well as easier and smoother chambering and ejection. Multiple set screws secure the laser diode, ensuring it stays straight and centered. To test, just roll the boresight on a flat surface and you’ll notice the laser stays straight along the wall your pointing it at.

Featuring an internal rechargeable battery and automatic on and off function, the Accudot laser boresight only activates when chambered, conserving battery life.

With visibility up to 100 yards, Accudot rifle boresights get you dialed in close to center-mass and at 25 yards, you’ll be close to the mark at a 100 sight-in. In lower light, boresights can reach quite a bit farther at 50 yards to close in on that 200-yard zero—the typical ranges for target shooting with your AR-15.

How to Boresight Your AR-15 Rifle Indoors or Outside

  1. Charge your boresight using the included USB cable and charging station.
  2. Use a benchrest, shooting bags, or another stable platform. Make sure your AR is completely unloaded and pointed in a safe direction.
  3. Hang a target 15 to 25 yards out.
  4. Lock your bolt open to the rear.
  5. Put the laser boresight into the chamber.
  6. Slowly close the bolt. The boresight will automatically turn on when the bolt is closed.
  7. Line the laser beam on to the center of the target.
  8. Look through your optic and using your windage and elevation knobs, adjust the reticle, (dot or crosshairs) until it lines up with the dot of the laser.

To remove the boresight, open the bolt and eject the boresight like you would a live round.

In-chamber boresights have changed the landscape for precision, competition and target shooters, as well as hunters by saving gun owners a ton of cash and precious time. If anything, boresighting keeps your shots productive by getting you on target faster. There is no doubt about it, the Sightmark Accudot helps you achieve first-shot impacts on paper.
