Before you buy an AR 15 laser sight you need to understand some basic facts so you’ll make a more informed decision. Laser sights and scopes are very similar as they both use straight lines of light for targeting objects. There are different kinds available but basically all you’re required to do is aim a green or red dot on your target and start shooting.

→ Types of Laser Sights
As mentioned there are many kinds of laser scopes but the following are the most widely used and the most practical for the AR-15:
Real Laser Sight
This replaces your rifle’s rear sight with a laser that goes along the barrel’s topmost part. With real lasers you have the option of using assisted or manual scopes.
Laser Grip
The laser grip is the most advanced scope today and comes with a pressure sensor integrated in the gun’s grip, activating the laser when touched. One of the reasons why this has became so popular is that it reduces the risk of being detected at night.
Rail Mount Laser
This is by far the most affordable option and not a bad one either. With a rail mount laser, the scope is clipped to the rail using your firearm’s frame, allowing the sight to keep its pinpoint precision even if there is recoil. While effective, the biggest drawback with rail mount lasers is that it doesn’t work very well in a low light environment.
Guide Rod Laser
A guide rod laser is built into the gun, so there’s no risk of the scope accidentally coming off or getting out of alignment. Because the laser is placed very near the barrel, the guide rod is considered by many to be the most accurate scope available.
→ Consistency
You also need to consider the consistency of the laser beams, and they generally take two forms: pulsating and constant. Constant beams are the most ideal if you are going to use a real laser light scope because with a constant consistency the laser will always be on.
A pulsating laser on the other hand, is sometimes harder to spot for animals but easier for people, and it is a lot like a strobe light. For this type of AR 15 laser lights to work properly, the light needs to remain twice as long compared to the time it is off.

→ Red or Green Laser Beams
The difference here is more than just the color because each one has a different set of wavelengths, strengths and weaknesses that need to be considered.
Red lasers are the most widely used, the most popular and is considered the traditional choice. Even though they are cheap to produce, they are very durable and can work in hot and cold conditions. Usually the range is between 20 to 50 yards, although this can vary depending on the product. To this day red lasers are used by law enforcement officers in the US, a testament to their quality.
Green lasers represent the latest technology and they are easier to use in the daytime compared to red. Also, green lasers have a visibility range of more than 100 yards so it is perfect for use with a rifle. However, green lasers are expensive so they’re not as practical as red lasers.
→ IR Laser Sights
IR laser sights represent the highest quality of lasers and are most suited to use with night vision devices. IR laser sights are also distinguished by many features other scopes just don’t have. Among the many advantages they offer are: clear targeting even in low light environments, it allows you to shoot without being seen, infrared light is also very hard to detect unless you are using one as well. (when used indoors a supplemental light is needed for it to work though)
