Best AR-15 Offset Iron Sights [View-Throughs]

Need a quick transition from a magnified scope to close-up targets? Check out offset irons which give you a nice sight picture with a quick rotation.

Have you ever watched videos of 3-gun competitions only to wonder why some people rotate their rifle before firing?

Well, if you look closely, you’ll probably notice that most of them have a scope or magnified optic mounted on their gun as well, and that’s not a coincidence.

What you’re seeing is shooters aiming with offset iron sights. 

These are sights are that are mounted to your flattop rifle and are offset by 45-degrees.  

Say you’re rocking a scope but you need to quickly fire off a shot at a target just a few short yards away. 

Instead of spending the time trying to locate the target through your scope, all you need to do is rotate your gun slightly and line up the target with your offset iron sights.

This will take half the time that it would take to use your scope at shorter distances, making it offset sights crucial for competitions and real-life tactical situations.

Are Offset Iron Sights Better Than Inline Sights?

Better is a relative term, but they can be useful for in situations where you’ve got to engage a close target and time matters.

The benefit that offset iron sights has over inline sights is that you don’t have to take the time to flip them up in the moment. 

While most offset sights are able to be flipped up and down, leaving the sights in an up position won’t inhibit your scope like inline sights would. 

This means that engaging a short-range target is as simple as rotating your rifle 45 degrees and firing.

Offset irons can be especially advantageous if your optic device suddenly breaks, as that can seriously dampen your inline sights’ effectiveness.

More importantly, offset sights make it feasible to go between short and medium/long-range target without having to fiddle with your optic mount.  Because in a real-life scenario, nobody has the time to take off their scope before engaging a target!

On the other hand, there is a learning curve that comes with offset sights. 

It might take some shooters some time to get used to rotating their rifle, especially when they need to take a shot in a short amount of time. 

Furthermore, offset sights can be a nuisance and get snagged on things if you’re not mindful of them.

Best AR-15 Offset Iron Sights

Now that we touched on the benefits that come with offset iron sights, are you thinking about adding some to your rifle? If so, you’ve come to the right place, because today we’re going to look at two quality sights that will turn your rifle into a tactical powerhouse.

1. Rapid Transition Sight with Trijicon Night Sights by Dueck Defense

When it comes to quality sights, 3-Gun legend, Barry Dueck is a name you can trust.  For this reason, offset irons made by Dueck Defense have been some of the more popular BUIS for some time, and the Rapid Transition Sights are no exception.

Barry Dueck Aiming with Rapid Transition Sights

Dueck came up with the Rapid Transition Sight to maximize his proficiency in run-and-gun competitive shooting scenarios, while also being able to use a powerful optical mount.  And out of that need, the Rapid Transition Sight was born.

Aside from the rather expensive price tag, what sets these sights off from other offset irons out there is their heavy-duty design. 

Made from the lightweight 7075 aluminum alloy, the Rapid Transition Sights aren’t only lighter than your average offset, they’re stronger as well – twice as strong as the standard 6061 T6 aluminum sights, to be exact!

If you’re wondering why anyone would pay so much for sights just for increased durability, remember that offset sights tend to catch a lot more wear and tear than inline sights because of their positioning. 

The last thing you want during a 3-Gun competition or an emergency situation is to accidentally bang your site against an object and break it.

Of course, Dueck has also come up with a solution to the unwanted profile increase that comes with offset irons by making sure that the Rapid Transition Sights are low profile.  The mount only rises 2/10th of an inch higher than your Picatinny rail, so don’t worry about them blocking your primary optic.

2. MBUS Pro Offset Sights by Magpul

Magpul is another leader in aftermarket tactical gear, so it should go without saying that Magpul sights tend to sell themselves.

You may have already heard of the MBUS Pro inline sights.  They’ve been a popular line of backup irons for some time now because of their durability and dependability. 

Well, these sights are exactly the same as their inline variants, except that they’re made for shooters who prefer to aim with offset sights rather than inline flip-ups.  Aside from that, you get the same quality and durability that comes standard with Magpul sights.

As you can see, the MBUS sights are significantly cheaper than the Rapid Transition Sights mentioned above.  While arguably just as good in a fast-paced scenario, the MBUS Pro doesn’t come with fiber optics or tritium finish – so you’re getting very basic, straightforward sights…

…Still, the MBUS Pro sights are more than capable of handling whatever you’re able to throw at them. 

They’re made completely from steel and can take a bit of banging around – not that you’d want to do that! And to further sweeten the deal, they’ve also been given a coat of Melonite QPQ to keep them protected against corrosion.

Like standard iron sights, the MBUS Pro offsets can be adjusted for elevation and windage without the need for tools.  The front and rear sights come with a low profile design that makes them compatible with virtually every rifle configuration.  All you need is a Picatinny rail system and you’re good to go.

What’s your take on these bad boys?

3. Ade Advanced Offset Sights

Now, those first two are what you want if you plan on depending on your offset irons when you need them, but maybe you just want to play around with the idea before committing a bag full of money.

Thankfully, there is a budget option in the Ade Advanced Offset Sights.

Made from 7075 aluminum with a hard anodized finish and sporting 1/2 MOA elevation and windage adjustments, these are surprisingly decent sights for the price.

And they look decent on any rifle.


But most importantly…they give you a decent enough target picture to score some easy hits against human-sized targets up close and personal.

No frills, no night sights or anything else, but good enough for range day trips and for testing out to see if the offset irons concept is right for you.

That’s Everything for Now

That’s it for the basics of offset iron sights.  If you’d like to learn more about different types of scopes put on your rifle, hop on over to our in-depth guide for rifle scopes and look at some of the equipment we covered.

Also, understand that offset iron sights aren’t for everyone.  If you’re not someone who needs to switch between long and short distances on the fly, there’s not much of a reason for you to get used to learning how to shoot with offset irons. 

And believe me, if you’re like most people, it will take some time to remember to rotate your gun when you first start shooting with offsets.

If the offset + high-powered scope doesn’t appeal to you, but you still need something that does give your accuracy a little boost without compromising your short-range shooting, look into scout scopes as a viable alternative.

If you’re a competitive shooter or tactical junkie, make sure to let us know how you like shooting with offset iron sights.  Want to go electronic or magnified?  Check out our Best AR-15 Scopes & Optics.

      You have 1 set, the 45 offset. Its attached to the picatinny rail. You transition from your magnified optic to these sights by simply rotating the gun.

    Griffin Armament makes a pretty solid contender that is ambidextrous. And for another $40, they can be provided with mounting plates that allow the sights to be mounted vertically, as well.

    You still need to zero the 45 sight. Not much difference at 20 ft, miss at 20 yards

    On the budget realm, Dagger Defense makes a flip up 45 offset, just as good as the ADE with the flip up advantage. They also are an American owned company with great customer service.

      I haven't tried their 45 offsets but I have a pair of their standard BUIS, surprisingly solid. I actually like them slightly better than my Magpul ones.

      Duck Defense make a left handed version. Some of the cheaper brands can be used flipped for lefty without much difference.

    I have two pair of offset sights that look very close to Dueck & Ade. I got them from Sportsman’s Guide for around $50 each. I think they were called XTS. They work great for me & I doubt I’d be willing to spend Dueck money. I doubt the Duecks are 4x as good. I did order a $20 set from Amazon once (not sure if Ade or other) & ended up returning them. They were very similar to those I got from SG but sloppy. It seemed almost like they were from the same factory but the SG set passed quality control & the Amazon set didn’t, hence the price difference. They’re the only offset irons I have though I might eventually get the MBUS Pros. I also have a Vortex Venom offset on two rifles with magnified optics & I really like that setup. But that’s another Pew Pew article.
