WINDAGE & ELEVATION ADJUSTMENTS
 Laser Sight | Rifle Handgun | Weaver or Picatinny Rail | Red Dot Lazer Sight Pistol | Tactical Sights Airsoft | Laser Sight | Scope Hand Gun Rifles | Laser Pointer Pistol | Air Soft Optic Laser Sight for Pistol Handgun, Green

 laser sights are pre-sighted at the factory to 50 feet. Many times no further adjustments are required. All products are fully adjustable for windage and elevation if further adjustments are desired. A good starting point is to align the laser with the fixed sights on the firearm. IR PRODUCTS REQUIRE THE USE OF IR CAPABLE OPTICS.
A two-screw alignment system is used to adjust for windage and elevation. The adjustment screws are located just behind the laser source, use the supplied allen wrenches to make any adjustments. Refer to the figure below and reference your particular model for sighting instructions. For additional information on your model, please refer to the installation guide included.
DO NOT OVERTURN THE ADJUSTMENT SCREWS.
A little adjustment goes a long way. Rarely is more than a half a turn is required to make your needed adjustments.

Start by lining your laser sight up with your fixed sights at a desired distance. Most people sight in their laser at between 20 and 50 ft. However because of the offset between the laser sight and the bore, the actual change in point-of-impact at these distances is very small.
Further adjustments can be made at the range to determine where your bullet impacts in relation to your firearms fixed sights. The laser should be moved to the actual impact point of the bullet .

TROUBLESHOOTING

Occasionally one of the adjustment screws will turn but not adjust the beam. If this happens, turn the windage and elevation screws counter clockwise until 1–2 threads of the sight screw are protruding from the housing of the diode. (DO NOT remove the sighting screws from the grip. If sight screw is removed you will need to send in your laser sight for repair (if necessary, refer to warranty work instructions  of manual). Once 1 – 2 threads are visible, lightly tap on the side of the diode housing with your finger to help reset the sighting spring. To finish, turning a 1/4 turn at a time, alternate from windage and elevation to slowly sight in your laser sight to your fixed sights.
NOTE: The Laserguard elevation screw is recessed, therefore the left side of the Laserguard will need to be removed to make the threads of the sight screw visible. Follow instructions above, and reinstall right side of Laserguard prior to realigning your laser sight.

MAINTENANCE
Laser sights require minimal attention and are designed to resist most common firearm chemicals and lubricants, however, excessive exposure to these chemicals can be detrimental. To ensure the safe and effective operation of your laser sights:
> Remove Laser Sight before cleaning gun.
> Do not use pressurized or compressed air.
> Do not immerse in cleaning fluid or lubricate firearm excessively. A firearm that has too much oil will foul the lens of the laser and result in an unfocused beam. This can be easily cleaned and causes no permanent damage.
> Do not allow cleaning solution to enter lens source.
> Do not allow solvents to contact your grips that contain: VOCs or TCE such as: carb/brake cleaner, acetone, MEK, gasoline. Grip damage will result.
>  diodes are designed and positioned to minimize exposure. Occasional cleaning
of the lens is recommended.


AFTER EXTENSIVE SHOOTING, YOU MAY NOTICE A DEGRADATION OF
BEAM QUALITY OR “BEAM SPREAD”. THIS IS THE RESULT OF FOULING
ON THE LENS SURFACE. THIS IS NORMAL AND CAN BE EASILY CLEANED
WITH THE INCLUDED CLEANING SWABS OR A SMALL COTTON SWAB

How to zeroing subcompact pistol green aiming laser sights?How to Sight In a Laser Sight for Your Pistol



How to Sight In a Laser Sight for Your Pistol
The information out there on the internet and forums on how to zero in your laser sight is sort of well, all over the place. Some resources say to sight in at 50 feet or further while some other say to try sighting in at 10 feet or the average distance for confronting an attacker (whatever that is!).

zeroing in a pistol laser sight

In this post, we’ll go over a simple way to zero in your handgun no matter if you have a laser sight on your rail or on your pistol grip.

Want a sure-fire way to sight in your new laser sight? Just use a laser bore sight instead of doing it manually.

First Step: Install Your Laser Sight Correctly
This might seem pretty obvious but you need to make sure that the laser sight on your handgun is installed correctly. To do this, you need a quality laser sight that fits your gun well.

On my Glock 17, I’ve currently got a Crimson Trace laser installed on the rail. It doesn’t budge when I shoot, it has no play in it whatsoever so that I know it’s not moving.

Now I’m not saying that you need to lay down the cash for a Crimson Trace but whatever handgun laser sight you buy, make sure it’s well reviewed and NOT a cheapo laser pointer with a rail mount on it. Also, make sure that the laser sight you do have has windage and elevation (up and down) adjustment screws on it or some way to adjust it.

Follow the manufacturer’s supplied directions and make sure that everything is tight on your handgun’s accessory rail.

Next Step: Shooting a Group at Distance
Go to your local gun range and get a clean target ready. Not a human silhouette, but an actual target, possibly like this.

Now we’re ready to get started. Make sure you’ve got your allen wrenches ready (or whatever method to adjust windage and elevation is on your laser).

Move your target back to about 30 feet. Yes, we’re going the distance!

The reason for starting at 25 or 30 feet is that you will be able to account for the trajectory of your bullet at this distance. We want to make sure your pistol laser is accurate both at distance and close range.

Think about it this way: if you were to hold your pistol point blank at the center of the target (looking down iron sights) and pull the trigger, your bullet hole would be a bit higher than where the laser dot was. That’s because your laser is mounted on the undermount of your pistol or to the side if you’re using a laser grip. We need to account for this in some way and that’s why we’re not starting at point blank range.

So at this point fire a group of 4-6 rounds aiming for the very center of the target. Prior to squeezing the trigger, make note of where the laser dot is in relation to where your iron sights are having you aim.

Take note of your group, but don’t reel in your paper target yet! You might need binoculars or high-visibility paper targets to do this depending on your eyesight.

Now, take aim again at the same spot down your iron sights with the laser turned on. Once you’ve gotten a good sight picture with your iron sights, take note of where your laser sight’s dot is in relation to the center of your group, not the center of the target.

Make some slight adjustments to your laser’s windage and elevation if your laser dot was not in the center of that group.

Keep doing this at 30 feet until your laser dot is in the center of your group. Remember, aim for the center of the target with your iron sights, fire 4-6 rounds then make adjustments as necessary to your laser sight until the dot is consistently in the center of your group. I would keep doing this for about 5 sets of 4-6 rounds until you’re satisfied with the consistency.

Getting Closer: Getting Zero on Your Laser Sight at Close Range
Once you’ve gotten consistent results at 30 feet using the method above. Now get a fresh paper target and move it back to about 10 feet.

Do the same thing again: shoot 4-6 shots aiming down the iron sights and make adjustments until your laser is in the center or very slightly lower than the center of your group, not the center of your target. If the center of your group is the center of your target, then that’s fine.

Have You Figured Out This Method of Sighting In Yet?
Basically, it is a given that everyone on Earth that owns a gun isn’t a sharpshooter by any means. Rather than adjusting your laser sight to zero on the iron sights (where you’re aiming on the target), you’re adjusting for where your shots are actually going.

Hopefully, your shots are very close to where you’re aiming (having a laser sight is NOT a replacement for good marksmanship and practice). We want to get that laser dot as close to the center of our groups as possible at any distance.

This is all done so that in a panic situation, you will raise your pistol up and be able to quickly get on target with your laser every time.

Alternative Laser Sighting Methods for Handguns
You may find that no matter what, you can’t get a good zero following this method. I would recommend using a pistol rest if you are having problems, however, I always like to have people do this just using their own aiming ability.

I’d also like to share the absolute best video that I’ve found that mimics my exact method listed above. I do this on all of my laser sights and it works perfectly for me every time.

In the video, it seems that they don’t do the sighting in method at different distances but at one. I like to do multiple distances, near and far to get the best results. If done correctly, you’ll be able to aim the gun with laser attached in awkward positions and still get relatively good accuracy.

532nm Green Laser Power Adjusting


Gun Aiming Laser Mounting and Zeroing


Here are a few things I learned about mounting and zeroing IR devices that can be applied to this longer-range class of visible lasers as well.
MountingA laser's position on the rifle will affect several functional aspects, including manipulation of controls. Most tactical rifles have factory or add-on rails present, and all modern rifle lasers I've seen have rail mounts. If your laser has no remote capability, it should be positioned close enough to the support hand to allow easy manipulation of the controls without a dramatic shift in hand placement. Ideally, you'll want to be able to momentarily activate the laser on demand, without "burning" it constantly. This will both save battery life and reduce your signature. If you plan to leave the laser in place long-term, a mild thread-locker that creates fastener-friction will help the device remain in place during hard use. Be sure not to use any thread-locker that requires heat for removal. Polymer laser housings and sensitive electronics won't fare well under even short-term torch heat.


The divergent laser line (LL) and line of bore (LOB) force us to compromise when determining how best to zero the laser for our needs. There is no perfect solution. Fortunately, many commercial visible lasers allow mounting in line with the LOB.
ZeroingBe conscious of where the laser's line (LL) is in relation to the line of bore (LOB) when choosing a mounting location. Just like a riflescope's line of sight, the LL and the LOB require a merging of sorts in order to place rounds on target. The closer they are on the rifle, the easier it is to zero the laser. Problems arise from the fact that the LL is usually offset from the LOB in a compound direction (i.e. up/down and left/right). Two popular zero methods are used to deal with this problem: Point of Aim/Point of Impact (POA/POI) and Offset. The POA/POI method is similar to that used for sight zeroing, in that you select the range where you want the LL to intersect with the bullet's POI and adjust windage and elevation accordingly. The problem with this method is the actual zero distance is the only place where they intersect. The further the projectile is from that zero distance (in either direction), the greater the deviation. Think of the LL and LOB forming a big "X" with the zero range being in the center. Realistic engagement distances are relatively limited with a laser, so this isn't a problem for most routine shooting. However, you still need to know how far off the projectile will be from the laser at different distances. I used this method in the Army, and it worked fine for shots out to 200 meters with 5.56 NATO and approximately 300 meters with .308 Win. Beyond those distances, I used different aiming devices for night shooting.
The offset (or parallel zero) method is commonly taught and used, but is often misunderstood. This technique requires you to measure the deviation from the LL to the LOB in direction and distance. The idea is to zero the laser at a specified range—usually 100 meters—so the LL (indicated by the laser's spot on target) is the same direction and distance (in inches) from the bullet's POI as the LL and LOB are on the gun. The theory usually given for this method is LL/POI deviation remains constant far enough out, the shooter need only hold slightly off of the intended POI and fire, regardless of distance. Unfortunately, we don't shoot in a vacuum, so gravity and atmospheric effects influence bullet flight paths to be anything but parallel to the LL. In other words, the bullet is going to drop farther and possibly be pushed by the wind from its zeroed POI as it continues downrange. So, the relationship between the LL and LOB zeroed-in at 100 meters is going to change with increased distance. If bullets flew the way lasers are projected, life would be much simpler for shooters.
A good partial remedy to both of the above methods' flaws is to mount the laser so that the LL is directly above or below the LOB. The result is that normal trajectory (without wind effects) will plot the POI directly above and below the visible laser's "spot" out to several hundred meters (before spin drift becomes a factor). It's much easier to account solely for elevation holds than for an elevation and windage divergence that changes with distance. Most military laser designs don't allow this due to their width, which makes me wonder why someone hasn't developed an offset mount to solve this problem.
These two methods are probably the most commonly used to zero long-range lasers. While not perfect, each represents a compromise that allows functional use out to moderate ranges.
One last trick is to use your zeroed iron or optical sights to quickly get your laser on target when zeroing. After both are zeroed, you can check one against the other to ensure nothing has changed from time to time. I recently tested a $200 green rifle laser that would not hold zero from one shot to the next. Don't trust literature, sales pitches or gun writers with your life. Test your laser's mounting and zero methods at multiple ranges in day and night conditions thoroughly before relying on it for real world needs.
