Pros and Cons of Iron Sights

Recently, iron sights have revolutionized many types of shooting. Whether you are in a battle or love hunting, you can always go for iron sights to enhance your potential. In this section, we have discussed the pros and cons of iron sights so that you can determine if you want to invest in these. 

Pros

By investing in a quality iron sight for your AR-15, you’ll get to enjoy the following benefits:

Cheap

Iron sights are relatively cheaper than other fighting optics. You can easily find a good set of iron sights even though you are budget-conscious.

Reliable

These accessories are quite reliable for their durable construction and commendable performance. They are quite fast in operation and provide accurate target acquisition. Moreover, a great iron sight will enable the shooter to focus on the front sight to make a fine alignment.

Lightweight

Another quality of iron sights is that they are extremely lightweight and, therefore, can be carried around easily. They generally weigh a couple of ounces at most, making them an ideal choice for hunters who’ll be carrying the rifle for a long time. 

Cons

Like everything, iron sights also come with their limitations. These include:

No Magnification

One of the major drawbacks of iron sights becomes apparent in low-light conditions and at long ranges. The aperture is unable to capture much light and, therefore, is not suitable during hunting at dawn or dusk.

Limited Range

Although shooters are capable of making ideal shots at 1000 yards, this does not make iron sights suitable for hunting at such distance practically. The maximum hunting range of iron sights is generally considered to be about 300 yards only. 

How to Zero AR-15 Iron Sights

A good set of iron sights will serve you in the long run, only if you zero them accurately. One of the common errors people make these days is they never zero their iron sights at all and, therefore, end up having ineffective results.

The zeroing procedure ensures that the weapon is performing at a specific range to target as per the expectations. Read on to find the detailed process for zeroing your iron sights. 

Choose the Right Distance

Firstly, place your rifle on a stable surface to avoid any awkward movement. Now, choose an arbitrary distance to zero for, including 25, 50, or 100. Figure out your desired point-blank zero according to your rifle.

Set the Target

The next step involves placing the target 25 yards downrange. It makes your sight adjustments quite easy.

Establish the Position

Now set your position by considering your shot hits. You can use a tool to adjust the front sight post up or down. Similarly, the rear sight windage knob is adjusted accordingly.

Fire Five-Rounds and Adjust

Now shoot five-round groups and determine exactly how to adjust your sights. Do this until you get the desired point-of-aim.

Confirm Iron Sight Zero

The last step involves confirming the iron sight zero. Set the target to 50 yards and then 100 yards respectively and repeat the process to finalize your zero.

Tips:

  • In case you face difficulty dialing in your zero, at least try to adjust the elevation and windage.
  • For beginners, start by putting the target closer, say at 10 yards and get a zero at that distance. Then go for 25 and 50 yards.

You can view the video below for a detailed understanding of what was just described.

Conclusion

Although iron sights do not use cutting-edge technology, they are still very reliable and, if trained properly, you can’t go wrong with shooting up to 300 yards. These lightweight accessories are basically designed to increase your accuracy. Therefore, it is recommended to take a few factors into consideration first while making a purchase. Different models have different advantages, so the ultimate choice definitely depends on your demands.
