Best Red Dot Placement on AR 15: Tips and Comparison


The AR 15 rifle is one of the most popular firearms in America. It’s versatile, customizable, and easy to handle. One of the key components that make an AR 15 effective is its red dot sight. A red dot sight can significantly improve your accuracy when shooting at targets.

But where exactly should you place your red dot on an AR 15? In this article, we’ll discuss some tips for finding the best placement for your red dot sight.

Benefits of Using a Red Dot Sight

Before we dive into the specifics of placing a red dot sight on an AR 15, let’s quickly go over why you’d want to use one in the first place.

Firstly, a good quality red dot will help you acquire targets much faster than traditional iron sights or even magnified scopes. Secondly, it allows both-eyes-open shooting which greatly increases situational awareness and peripheral vision while maintaining accuracy.

Another major benefit is that they’re incredibly simple to use; simply aim at your target using a bright illuminated point instead of lining up three dots with small peepholes like traditional sights require.

Lastly – and perhaps most importantly – using a high-quality optic can increase confidence in shot placements as well as speed up follow-up shots.

Where Should You Place Your Red Dot Sight?

The ideal placement for your red-dot-sight depends somewhat on personal preference based upon factors such as how long-lasting comfortability during firing sessions will be important. That said there are two main options for mounting positions:

  1. Co-witnessing with iron sights

  2. Mounting solely onto receiver rails

Option One: Co-Witnessing Iron Sights

Co-witnessing involves mounting both irons (front & rear) along with the optic allowing them all to be used simultaneously if needed due any technical failure or obstruction to your optic. This method was primarily developed for military use, where it’s crucial to have a backup plan if the primary red dot sight fails.

With this setup, the iron sights are in-line with the optic providing an easy-to-use backup for when you need it most. A popular co-witnessing option is achieving absolute co-witnessing height, which allows equal positioning of both irons and red-dot-aiming point (the center of reticle), creating a clear unobstructed view of all three simultaneously.

Option Two: Mount Solely onto Receiver Rails

The other option is mounting your red dot solely on the receiver rails without any additional iron sights present.

When using this method, you’ll want to consider what kind of shooting you’re going to be doing. For example:

  1. If long-range shots are expected then a higher magnification scope may suffice better instead.
  2. Whereas shorter ranges might only require a single-point zero magnification sight (also known as reflex or holographic sights).

Which Option Should You Choose?

Ultimately there’s no one-size-fits-all answer – choosing between these two options comes down largely based upon personal preference.

That being said if longevity and durability is important then opting for co-witnessed optics mountings should be considered as it provides redundancy in case something goes wrong with the optic itself like running out battery life or taking any damage from impact during accidents.


Finding where exactly to place your AR 15's red-dot-sight can seem confusing at first glance but once understood properly its actually quite simple! Optics placement depends heavily on situational needs along with what feels comfortable while firing – whether that be solely mounted onto receiver rails or complete cowitness surrounding by ironsight backups.

Just remember that using an excellent quality range-proven optics solution will ultimately lead towards maximising performance benefits gained from investing into such equipment upgrades.


What is the red dot placement on AR-15?

Red dot placement on AR-15 refers to the positioning of a red dot sight on an AR-15 rifle. The red dot sight provides shooters with aiming precision and accuracy, allowing them to hit their targets more effectively. Having a well-placed red dot sight can make all the difference in hitting your target consistently.

The ideal position for your red-dot scope may depend somewhat upon its design and how you intend to use it. Some scopes are designed for close-quarters combat and rapid acquisition, while others are better suited for longer-range shots or tactical engagements that require greater precision.

In general, it's best if you can place your scope as far forward as possible without interfering with anything else mounted on your weapon system (such as lights, lasers or other optics). This helps ensure that you have a clear field of view when looking through the optic and minimizes any potential parallax errors.

Is there any preferred location for mounting a Red Dot Sight?

There is no one-size-fits-all answer here because different shooters will have different preferences when it comes to where they want their sighting systems installed – but some general guidelines apply:

  1. Mounting at least 1" above bore axis: When selecting where to place your optic along the rail system of an AR-style rifle platform, try not go lower than 1-inch above bore axis height in order to avoid having bullet hits impacted by barrel movement;

  2. Forward Optic Placement: Red dots normally employ low magnification lenses / assemblies that allows quick target acquisition. Besides this fact many seasoned gun owners like putting their sights closer towards muzzle even if they won't be using iron sights simultaneously;

  3. Eye Relief: For some people eye relief may also play into this equation depending upon what shooting positions will most commonly be used (e.g., prone vs off-hand), so consider these factors before making final decisions about where to mount your red-dot optic.

How do I zero my red dot sight on an AR-15?

Zeroing a Red Dot Sight is the process of aligning the point-of-aim with the point-of-impact at a given distance. The following are some steps you can follow:

  1. Start at 25 yards: This is typically where most people start when zeroing their rifle, since it's close enough that they can still see what they're doing clearly but far enough away that any errors are magnified and easy to correct;

  2. Shoot groups of three: Fire three rounds at your target from a rested position. This will give you an accurate representation of how consistent your shots are;

  3. Adjust and repeat: Use the knobs or screws on your scope mount or sight housing to make adjustments based on how far off center each group was from where you were aiming. Re-fire another set grouping of three shots, making additional adjustments until all rounds cluster in very tight groups.

Remember that there isn't one "correct" way for everyone to zero their rifles – this is largely dependent upon individual preferences and shooting styles – so don't be afraid to experiment!

What range should I choose when sighting in my Red Dot Sight?

Determining what range for sighting-in (zero'ing) should be chosen depends heavily upon individual factors like personal preference, rifle configuration, ammunition choice etc. However, as rule-of-thumb:

  1. Average Range Distance – For law enforcement use or home defense situations with short-range confrontations expected (e.g., up-close work inside homes / buildings), many people opt for 50-yard zeroes since these distances tend not exceed over hundred feet;

2)Larger Range Distance – If looking for longer ranges than just indoor engagements then somewhere around 100 yards may serve well.

Can I use other sights along with my Red Dot Sight on an AR-15

Yes! There are a variety of other sights that can be used in conjunction with your Red Dot Sight to help you shoot more accurately and effectively downrange. For example:

  1. Iron Sights – If you're looking for a low-profile sight that will still give you accurate results, iron sights may be the way to go. They offer quick target acquisition at short ranges, making them ideal for use in close-quarters combat or tactical situations where speed is of the essence;

  2. Magnifiers – Adding magnification capabilities enables precision shooting further out from 100 yards.

  3. Offset Sights – These are side-mounted aiming devices which allow rapid transition between primary and alternate sighting systems without adding bulk or altering firing grip on one's rifle.

Ultimately, choosing what other accessories to pair with your red dot sight depends largely upon individual preferences based on budgetary considerations as well as specific shooting needs; there are many affordable options available depending on how much money one is willing spend!
