M-Spec Red Dot Sight is Ready For Duty

The Sightmark M-Spec takes a beating from the Cheyenne, Wyoming police department and proves it’s a durable and reliable piece of essential gear.

Our country’s police forces wouldn’t be able to protect and serve without reliable equipment. They are better prepared to do their duty safely and swiftly when they are equipped with dependable gear they can trust. Sellmark Corporation Senior Law Enforcement Sales Representative Rich Collier who is also a current Deputy Constable of Tarrant County and former Chief of Police says law enforcement need their equipment to be reliable, cost-effective and have a good warranty. It is a tough job evaluating a new product. Getting it wrong can cost innocent lives. How can they be sure it won’t fail when it really matters?  In 2017, Sellmark added a dedicated team to support local, state, national and even international law enforcement personnel. With new GSA-approval, it is now easier for government agencies, including law enforcement, to purchase Puslar, Sightmark, Firefield and 12 Survivors products. Sellmark stands by its products and without hesitation will send them out to police departments for review and testing.

For 18 days, the Ultra Shot M-Spec was pushed to its limits and didn’t fail once.


One product that both law enforcement and military find useful is a red dot or reflex sight. These optics provide quick target acquisition and accurate shots, are easy to use, perform well in low-light, and allow the user to aim and shoot with both eyes open, which is important to staying situationally aware.

From February 8 to February 26, 2018, the police department of Cheyenne, Wyoming ran the Sightmark Ultra Shot M-Spec FMS (SM26010) through the gauntlet. In fact, they performed more rigorous testing on a product than any other department. Officer Young of Cheyenne, Wy PD pushed the M-Spec to its limits and it exceeded expectations.

The Ultra Shot M-Spec is a night-vision compatible reflex sight with an illuminated red 65 MOA circle dot crosshair reticle with 6 brightness settings.


  • 65 MOA red Circle Dot Crosshair (60 MOA circle w/ 5 MOA sub tension, 2 MOA central dot)
  • 8 brightness settings, 6 night-vision compatible settings
  • 33×24 window
  • 105’ field of view at 100 yards
  • Unlimited eye relief
  • 120 MOA elevation adjustment
  • Up to .50 caliber recoil-resistant
  • IP68 IP Rating, submersible to 40’
  • Weaver/Picatinny mount
  • CR2 battery with up to 1,000 battery life
  • Parallax-corrected lens system from 10 yards to infinity
  • -22 to 160 F operating temperature
  • 103mm long x 49mm wide x 61mm tall
  • Weighs 7.5 ounces
  • Cast magnesium housing with protective shield
  • Automatic shut off after 5 minutes of no motion

Here is the detailed account of the test:

Cheyenne, Wyoming PD received the unit along with a magnifier on February 8, 2018. It mounted quickly without issue to a DPMS AR-15 and was easily zeroed at the range. The leaver on the magnifier got in the way of the rifle’s charging handle but changing the lever to pull closed to the front made it fit better. Shooting several drills at steel targets at 100 to 25 yards, the M-Spec’s dot was easy to see and got on target quickly. After 180 rounds, the optic was still holding zero.

Drop Testing

Banged up reflex sight
This unit was dropped and thrown repeatedly and never lost zero.

The DMPS rifle was tipped over on its side 20 times and the Ultra Shot M-Spec still held zero. The magnifier was removed, and the rifle was tipped over again on top of the sight and it still held zero. The rifle was dropped from a height of 3 feet onto its side an additional 20 more times. Zero was still held. Then it was dropped from 4 feet directly onto the optic 5 times and removed from a vehicle 20 times. It was after this round of testing that zero moved three inches high.

On 2/26/18, the rifle was dropped directly on top of the optic from three feet and again, it kept zero. To test the durability of the optic by itself, it was removed from the rifle and thrown 10 feet into the air, allowing it to hit the gravel 5 times. It still held zero. Additionally, the M-Spec alone was thrown about 20 feet into the air 5 times and still held zero. The sight by itself was thrown down range 30 yards and it still stayed zero. Thrown 30 yards again—it still held zero. Thrown 45 yards down range and it stayed zero. While taking the optic on and off the rifle, Officer Young accidentally over-tightened the rear mounting screw, stripping the screw. The M-Spec had not been turned off since the department received it on February 8 and was still fully operational.

Extreme Temperatures

Two days after getting the Sightmark M-Spec, Officer Young froze the rifle with the red dot attached in sub-zero temperatures and poured water over the optic and magnifier.

After freezing, on February 13, 2018, the M-Spec was still functioning at full power, despite having been turned on since the 8th. The magnifier needed slight adjustments to bring the reticle back to center. Despite this, the M-Spec was still holding zero.

Officer Young put the rifle with the optic attached in a hot shower and then froze it in a sub-zero temperature for three hours. It was frozen multiple times and tested for fogging.

After finishing the drop and extreme temperature tests, Officer Young drove around with the rifle and M-Spec in his trunk for two days. He slid it down a flight of carpeted stairs. After all of this, he fired 60 rounds and found that zero was still held.

After test and evaluation were finished, the Cheyenne, Wyoming PD ordered 10 units for law enforcement use.

Boresighting a Pistol

 “When you read about “accuracy” of any given handgun, know that unless machines are involved, what you’re really getting is an indication of that pistol’s ability to be shot accurately. — Tom McHale Shooting Illustrated

When we say a pistol is ‘accurate,’ we mean it consistently hits where we aim. A lot goes into whether a gun is accurate. The barrel, fittings and how precisely-machined all the parts affect accuracy. The sighting system affects accuracy. But we can’t blame all accuracy issues on the pistol. Most accuracy problems originate with you, the shooter. If you have the fundamentals of pistol shooting down—your aim, stance, grip and how you manipulate the trigger—than you should be shooting pretty darn straight. If you are still having problems punching holes into holes from a self-defense distance (10 feet and under), there just might be an issue with the gun.

So, where do you begin?

Inserting a laser boresight into a Ruger pistol
Increase your accuracy with Sightmark’s in-chamber boresights.

Let’s start by inspecting the sighting system you have on your gun—iron sights, night sights, lasers and red dots all need sighting-in to make sure they are aligned properly. Surprisingly, a lot of us just compensate our aim to match that of our gun’s sights from the factory. For example, if your sights are off, which they could very well be, we simply just shoot low left, or high right—whichever way your sights are set—to hit bullseye. It is not good to compensate our aim for offset optics or sights.

Why does accuracy matter?

To stop a threat, you must be able to hit vital organs. Inaccuracy could mean the bad guy wins.

What Happens to Your Body During a Self-Defense Shooting

When we are faced with a threat, our bodies dump adrenaline, norepinephrine and cortisol into our bloodstream, preparing us to either stay and fight or run. Our heart rate, blood pressure and breathing increase, our pupils dilate and our muscles tense. This dump of hormones can cause memory problems, loss of hearing and create tunnel vision.

In a self-defense situation, you won’t be able to take your time to aim. You won’t focus on the front sight. That is why we put lasers, red dots and high-visibility aftermarket sights on our handguns. Anytime we get a new handgun or a new sighting system, we need to make sure our sights or optic is centered with the bore. This makes your gun more accurate. An in-chamber boresight is a perfect way to do this and saves you time and money.

What is a Laser Boresight?

Zero your pistol from 15-100 yards.

A laser boresight is a preliminary method of getting your sights dialed in without using a lot of ammo at the range. Using a laser diode, it projects a red dot on a target, making it easier for you to center your sights and optics. Sightmark’s pistol boresights are caliber-specific and placed directly in your firearm’s chamber.

How to Boresight a Pistol

Using a pistol boresight is simple.

  1. Unload your firearm and pointing it in a safe direction, stabilize it using a benchrest or shooting bags.
  2. Hang a target 15 to 25 yards out.
  3. Unscrew the bottom of the boresight and insert the batteries according to the instructions. The boresight automatically turns on when the batteries are inserted correctly.
  4. Put the laser boresight into the chamber.
  5. Close the slide.
  6. Line the laser beam on to the center of the target.
  7. Look through your optic and using your windage and elevation knobs, adjust the crosshairs or dot until it lines up with the dot of the laser boresight. If you do not have an optic and just want to calibrate your sights, aim as you would regularly and then use a pistol sight adjustment tool to correct for windage and elevation.

As mentioned above, most inaccuracy problems can’t be blamed on the gun. There are a few things we can do besides improving our own technique to help increase accuracy. Accuracy isn’t just for precision shooters or competitors. Accurate is something we must all aim to be. For a small price to pay and a few minutes, a laser boresight might just make all the difference.

Zero Your Handgun With Sightmark’s New .380 ACP Laser Boresight!

(MANSFIELD, TEXAS 2018/01/30) – Worry no more, .380 ACP owners—Sightmark has your zeroing needs covered with their redesigned .380 ACP Laser Boresight (SM39046).

Increase your accuracy with Sightmark’s in-chamber boresights.

Far more accurate than a muzzle-attached boresight, the Sightmark .380 ACP Laser Boresight chambers directly in your firearm, just like a normal round, allowing precision accuracy when sighting in. The boresight’s brass construction helps not only with durability, but also improves chambering and ejection. Extremely lightweight and no larger than a standard .380 ACP bullet, this boresight is easily stored for use at the range or ranch. The .380 ACP Boresight provides 1 hour of battery life from two AG5 batteries and includes batteries and a carrying case.

Zero your pistol from 15-100 yards.

How to Boresight a Rifle

When you purchase a new optic for your rifle, that optic is not going to be accurate right out of the box. Before depending on your optic to help you hit exactly where you mean, you’ll have to zero it. Sighting in your scope can take a long time and waste a lot of ammo. Fortunately, there is a solution.

There is a more efficient and faster way of zeroing in a new optic. By using a laser boresight, you save time and money by making sighting-in much faster without using any ammo!

Bore sighting is a reliable way to align your reticle, sights and scope’s crosshairs with the true center of the gun’s barrel—which is the bore. Boresights use a laser diode to project a dot on a target much like a laser pointer, making it easy to see when your crosshairs align with the laser. Since the two run parallel to each other, they can only truly zero at a given distance. This is typically 25 yards.

You can bore sight any firearm—AR-15 and other MSWs, shotgun, bolt-action, and handguns. Bore sighting also works on any sighting system—red dot, reflex, riflescopes, holograph and even your iron or night sights.

There are two different types of laser boresights—one you put directly into the chamber and one you insert into the barrel.


In-chamber boresights are inserted directly into your gun’s chamber, so they must be caliber-specific and made to the same dimensions and specs as a cartridge in that caliber. These types of boresights are the most accurate. These can, however, become costly If you have firearms in multiple calibers that you need to sight in, because you must purchase a separate boresight for each caliber.

In-chamber boresights are accurate and easy to use.

Laser boresight cartridges are easy to use. You simply turn them on and insert it into the chamber of your firearm like you would a live round or snap cap.

Sightmark in-chamber boresights are superior to competitors, due to the multiple set screws that lock in the laser diode, ensuring the laser stays straight and centered. To test an in-chamber boresight’s accuracy, roll your laser boresight on a flat surface, the laser should stay straight along the wall as you roll it. If the dot rotates, you know the diode is canted and you won’t be able to accurately zero-in your scope.

Made of high-quality brass, the Sightmark boresights are calibrated to make sure the laser is true to center, and measure precisely the same specs as a live round. The extensive offerings include 12- and 20-gauge shotgun, the most popular self-defense handgun calibers, and over 30 different hunting, defense, sporting, and popular rifle calibers—including .223/5.56, .308, .50, .300 BLK and 6.5 Creedmoor.

Using an In-Chamber Boresight

  1. Use a benchrest, shooting bags, or other platform that stabilizes your gun. Make sure the firearm is completely unloaded and pointed in a safe direction.
  2. Hang a target 15 to 25 yards out.
  3. Remove the batteries from the boresight packaging and unscrew the bottom of the boresight. Insert the two batteries according to the instructions. The boresight will automatically turn on when the batteries are inserted correctly.
  4. Lock your bolt open to the rear.
  5. Put the laser boresight into the chamber.
  6. You may close the bolt or leave it open.
  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 boresight.

Universal Boresights

Other boresights are either attached or inserted into the barrel. Most boresights that you must insert into the barrel come with a set of arbors that will modify the boresight to fit different barrel sizes. These types of boresights are the most affordable, but they do come with some disadvantages.

  • Arbors are small and can get lost easily. They also wear out and break.
  • The entire boresight itself can play against the barrel, causing inaccuracy.
  • Safety concerns. Forgetting to remove a boresight from the barrel can result in a catastrophic accident.

Sightmark’s universal boresights provide a much safer way to boresight if you prefer this type of boresight over an in-chamber boresighter. If you have looked at any firearm failure montages or spent any good deal of time on gun blogs and forums, you have probably seen the blown-up barrel caused by an in-barrel boresight. Our universal laser boresights securely stay on your rifle, shotgun, or pistol via a heavy-duty magnet. Only a small portion of the arbor goes inside the barrel. They incorporate a self-centering arbor, so you never have to worry about losing pieces or breaking parts. They will sight in firearms .17 to .50 caliber.


Using the Universal Boresight and Universal Boresight Pro

  1. Use a benchrest, shooting bags, or other platform that stabilizes your gun. Make sure the firearm is completely unloaded and point it in a safe direction.
  2. Hang a target 15 to 25 yards out.
  3. Remove the Universal Boresight from the package. Turn the unit on. To preserve battery life, the Universal Boresight Pro will only activate when the arbor is pressed in when it is attached to the barrel.
  4. Remove any suppressor or muzzle device you have on your firearm.
  5. Simply attach the boresight to the end of the barrel.
  6. 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 boresight.

It’s as easy as that!

Now, you are ready to head to the range to make precise adjustments to your riflescope. It shouldn’t take but a few rounds to zero it in.

You will want to bore sight your firearm any time you get a new optic, upgrade factory sights, for a competition, before hunting, and on a firearm that has been in storage.
