5 Best AR-15 Offset Iron Sights (Canted Iron Sights)

There are a lot of modifications you can make to an AR-15. One of the modifications in the optic field is Offset iron sights. These sights are mounted at a 45-degree angle and offer a backup aiming system for your primary optic. 

The five best AR-15 offset iron sights we listed in this article are backed by our own experience and rated according to the HuntersHalt standard. Also, make sure to look over our discussion on what to look for when buying an offset iron sight to ensure you buy quality and not a counterfeit.


What Is An Offset Iron Sight?

An offset or canted iron sight is a type of iron sight that is mounted at a 45-degree angle to the rifle’s bore. These sights allow shooters to quickly switch between their primary optic and the backup iron sights without adjusting their head position. They are mostly used as backup sights for red dot sights or other primary optics, such as LPVOs.

Offset iron sights have a lot of benefits over traditional iron sights. They are especially useful when you must engage targets at different ranges or lighting conditions.

What Are The Primary Benefits Of Using Offset Iron Sights?

The primary benefit of a 45-degree offset iron sight is its quick transition – allowing you to quickly adjust between your primary optics to iron sights without any adjustments. Additionally, offset iron sights also act as a backup sighting system in case your primary optics fail, get damaged, or fog up.

Finally, these iron sights also increase the versatility of your AR-15. When mounted, you can use your AR-15 effectively in long and short-range engagements. Most offset sights aren’t very durable, or the sight picture isn’t very clear. Therefore, you must buy quality to reap the full rewards of an offset iron sight.

The rear sight and front sight post are very well built and provide an efficient optical sight for rapid target shooting. They are also very easy to mount – you can attach them directly to your Picatinny rail.

However, at $209.95, they do cost a pretty penny. Nonetheless, if you are a competitive shooter who wants a high-performance offset iron sight, this is the one to get.

What To Look For When Buying Offset Iron Sights?

When buying an offset iron sight, it is important you pay attention to the following key factors.

  • Material and Build Quality: Make sure the iron sight is built from durable materials (aluminum or titanium). Also, ensure that it has lens coatings to add further protection against wear and rust.
  • Adjustability: Most offset iron sights will have an easy method of adjusting windage and elevation. However, I prefer tool-less offset iron sights – it’s just more practical, especially when you’re in the field.
  • Locking Mechanism: I like to see a secure lock-up in these iron sights. It ensures the sights stay in place, no matter what test you put them through.
  • Price: The sight must be priced within the bounds of its competitors. Suppose it’s surprisingly cheap; it’s most likely a counterfeit.

Do They Make Counterfeit Offset Iron Sights?

Yes, the market has been flooded with counterfeit offset iron sights. Always buy from reputable dealers or directly from manufacturers and make sure the product matches the description of the one the manufacturer’s website provides.


How Do Iron Sights Compare To Red Dot Sights For An AR-15?

Iron sights are more basic compared to red dot sights. While red dot sights offer quicker target acquisition and are more accurate, they do rely on batteries and electronics to provide an aiming platform. In comparison, an iron sight is mechanical – what you see is what you get. This makes them more reliable in certain daytime-use scenarios.


Can You Use Red Dot Sights With Canted Iron Sights?

Most definitely! Most of my AR-15s are rigged with a red dot & canted iron sight combination. The red dot acts as the primary optic, providing quick target acquisition and accuracy, especially in low-light conditions. The offset sight acts as the backup, providing a reliable fail-safe in case the red dot stops working.


What Other Modifications Can Be Made To Your AR-15?

AR-15s are renowned for their modularity. There are a plethora of modifications for your AR-15 – from trigger upgrades and handguards to barrels and complete receivers – the options are really endless.

However, make sure you only buy from reputable companies and that the individual parts are compatible with each other. This will ensure optimal performance and prevent potential damage to your weapon.


Frequently Asked Questions

How does the height of the offset iron sights affect co-witnessing with primary optics?

Iron sights should have an ideal height to allow for co-witnessing with the primary optic. This ensures proper alignment and accuracy.

Can offset iron sights handle recoil?

Yes, quality offset iron sights, like the ones mentioned in this list, can comfortably handle the recoil of an AR-15.

What is the biggest downside of using offset iron sights for an AR-15?

The biggest downside of mounting Offset iron sights is that it can make your AR-15 feel cumbersome. The iron sights add extra weight and bulk to your AR-15 rig and are prone to snagging on gear and surroundings.

The Bottom Line

Offset iron sights are an invaluable addition to any AR-15 rig. They offer versatility, reliability, and an edge in various shooting scenarios. However, it is important you buy quality, authentic products. This will ensure optimal performance and an enjoyable shooting experience. As always, happy shooting, and stay safe!
