The AR 15 Sights Buying Guide

A good set of iron sights provide the most basic means of aiming for the AR platform. In fact, if you don’t have upgraded optics it may be your only means.

In today’s world it seems that all shooters are trending towards putting some sort of optics on their rifle and bypassing traditional sights all together. However,  there is still a lot of functionality in AR 15 sights that make them a reliable choice for either primary or secondary aiming modes.

The Case For AR 15 Iron Sights

ar 15 iro sightsUpgraded AR optics have become ubiquitous in the military and civilian use for good reason. Clear shooting advantages like better accuracy, faster target acquisition, and increased range, paired with a cheap price tag makes for an easy decision to upgrade.

In fact, some factory guns don’t even come equipped with basic iron sights because it is assumed that an optic will be placed on it. A far cry from years ago when every new shooter had to learn the nuances of iron sights.

Don’t count iron sights out just yet though. It is the nature of their simple design that makes them appealing at times. What they lack in optical advantages they make up for in brute functionality.

  • Simple Design – With just two main components, a rear sight with a notch/aperture and a front post, to work with there isn’t much to over complicate the process.
  • Light Weight – Without the heavy glass components or batteries that optics utilize makes iron sights incredibly light in comparison. This can help with rifle balance and fatigue.
  • Weather Impervious – You’ll always be able to look through your sights no matter the weather condition. Fog, rain, or snow that will impact glass optics won’t have any effect here.
  • Co-witness/Backup – All the above reasons make them a great to use along with optics. The can be co-witnessed to be aimed inline with red dots or holographic sights or used in situations where the primary optic becomes damaged or loses battery power.

Types of AR 15 Sights

There are a few different options to look out for when searching for AR 15 sights. Variations come with alignment components, mount placement, primary functionality, and more which leads to a lot of different choices for shooters. The most important factor is finding a sight that enhances your AR system and how you operate it.

45 Degree Offset Sights

offset sightsPlenty of shooters have discovered that their optics aren’t ideal for every situation. A magnified scope is useless in close-range target scenarios and therefore requires secondary sights to be used.

45 degree offset sights provide this by mounting at an angle off the top rail, allowing shooters use them simply by rotating their rifle. Great for backups and making a rifle more dynamic, offset sights are a strong addition to any setup.

These are most often used in the military by soldiers who need to be able to engage targets both at CQC distances and mid/long range distances with a single rifle. For those who are issued a fixed power scope as their primary rifle optic, a set of offset sights becomes crucial when the fight is taken indoors. This same concept can also be done with small reflex sights.

Folding/Collapsible Backup Sights

Sometimes its great to have the option of keeping AR 15 sights out of the way until their needed, having them as hidden backups in case of a primary optic failure. In the case where a primary red dot sight runs out of batteries, or the optic becomes damaged, folding sights work as a failsafe so accurate aiming can still take place.

Folding sights can be pushed into a closed position so that they are out of the sight line and protected. Quick flip up options add a fast way to get them up and running during battle. The added benefit here is that, when in the folded position, they aren’t exposed to snag on gear or break off.
