Designed by former marine and 3-Gun legend Barry Dueck, this offset sight could mean the difference between winning or losing a match.

If you’re into competitive shooting, this is your BEST BET.  

Features & Specifications:

  • Material: 7075 aluminum alloy

The Dueck Defense Rapid Transition Sight is meant for run-and-gun competitive shooting scenarios!

Here are a few reasons why these sights are your best bet:

  • It is lightweight, so it won’t slow you down.
  • You don’t even have to worry about wear and tear.
  • The materials are TWICE MORE DURABLE than other sights. Yup, you can bang it ANYWHERE and not care AT ALL (but, seriously, take care of your things).

The MBUS Pro Offset Sights is one of the top backup sights in the market. It’s reliable and easy to adjust.

And the best part: The price won’t burn through your wallet!

Features & Specifications:

  • Material: All-steel construction
  • Weight: 0.24 lbs
  • Type: Flip-up
  • Mounting type: Picatinny

Our Overall Verdict

If you’re a fan of Magpul’s MBUS Pro inline sights, you won’t be disappointed with these offset sights. You can expect the same high-quality performance for short-range shooting.

We know some shooters like their offset BUIS to come with fiber optics for that accurate sight picture.

If that’s something you’re looking for, then MBUS Pro Offset Sights might not be for you.

But, if this is not a deal-breaker, you’ll be glad to know this offset iron sight is a great bargain for its price:

  • You can easily tweak its elevation and windage adjustments, so it won’t be a hassle to align it with your scope.
  • Also, compared with other sights, this offset BUIS is sturdy as hell!
  • The spring dent has a solid locking mechanism that keeps it in place. No matter how fast-paced the situation, you’re confident it won’t wriggle out.

It’s not like Dueck Defense Rapid Transition Sight or Knight’s Armament, but it gets the job done!

3. Tacticon Armament Offset Sights

BEST BUDGET PICK

Tacticon Armament Offset Sights

BUYING OPTIONS:
» Check Price on Amazon «

Did you know you can get your hands on these sights for ONLY $25?

This sight is perfect for beginners who want to figure out if using flip-up iron sights can step up their game!

Features & Specifications:

  • Material: Hardened aircraft-grade aluminum alloy
  • Weight: 0.25 lbs
  • Type: Flip-up
  • Mounting type: Weaver, Picatinny

Our Overall Verdict

Tacticon’s flip-up iron sights may come with a very low price, but that doesn’t mean it can’t deliver!

What makes this one of the best sellers?

  • It can function as your main sight or backup sight for your primary optic.
  • It’s specially designed for hunting or mounting on a rifle.
  • It fits a weaver or Picatinny rail system well.

We also appreciate that the sights are packaged in a neat wooden case. This case also keeps the sight adjustment tool, mounting wrench, and some EXTRA AMMUNITION.

BUT, we’re not saying Tacticon is a dreamboat.

Some shooters say it needs to improve its zero retention. And while it has SOLID SPRINGS, they don’t lay as flat as supposed to.

But don’t worry if you happen to encounter the same problem.

Tacticon values quality control and offers a LIFETIME WARRANTY for the sights. If you’re not happy with its performance, you can even request a full refund.

4. Troy Industries Offset Battle Sight

BUYING OPTIONS:

Like Dueck Defense, the Troy Industries offset battle sight is one of the best-sellers among special ops and tactical users worldwide.

With its easy install and deploy features, it’s no wonder why it’s a crowd favorite!

Features & Specifications:

  • Material: Aluminum
  • Weight: 0.35 lbs
  • Type: folding
  • Mounting type: Weaver, Picatinny

Our Overall Verdict

Left-handed? No problem.

Most offset iron sights only accommodate right-handed shooters. But Troy’s 45 degree offset iron sights can fold seamlessly on both sides of the rifle for an ambidextrous sight base!

If you’re a shooter who loves options, you’re in luck! Troy industries offer two choices for their backup irons: HK and M4.

What’s the difference?

  • HK comes with a circular peephole and front sight wings
  • M4, on the other hand, uses stand wings and a diamond peephole.

HK would give you the advantage of acquiring targets faster because of its dioptric effect. But, you might find it difficult to zero in the elevation adjustment tool.

So, if you can’t deal with all these extras, we suggest going for the M4.

TAKE NOTE: This iron sight is not compatible with every rifle configuration. It only works for same-plane rail systems.

5. Diamondhead – D-45 Offset Sights

Diamondhead - D-45 Offset Sights

BUYING OPTIONS:
» Best Price on OpticsPlanet «
» Check Price on Amazon «

From the company name itself, Diamondhead is famous for, well, its diamond-shaped apertures.

Now, don’t think those are just for design! It is helpful for faster target acquisition and centering.

With this baby, shooting a short-range target is EASY-PEASY. Just mount it on your Picatinny rail system, and you’re good to go!

Features & Specifications:

  • Material: Aluminum
  • Weight: 0.34 pounds
  • Type: Fixed folding
  • Mounting type: Picatinny

Our Overall Verdict

There’s a learning curve in familiarizing yourself with Diamondhead’s aperture. Some are even skeptical if it works.

But after some practice, your eyes will naturally find the center. Their unique design places the front sight post in the exact center of the rear sight aperture.

After trying these offset irons, we’re sure you’ll never go back to the standard circular peephole!

Also, this is the only offset sight that folds under the rifle scope. It means you can whip it out when needed and hide it when not used. Neat, right?

But, be EXTRA CAREFUL when using this!

  • It tends to scratch the finish of your rifle when it snaps out.
  • It can also scrape your scope if you don’t properly fold it.

6. Knight’s Armament Keymod 45 Degree Offset

Knight's Armament Keymod 45 Degree Offset

BUYING OPTIONS:
» DISCONTINUED BY MANUFACTURER «

The rugged and heavy-duty design of Knight Armament’s offset irons gives out the vibe that you’re ready for battle!

If you want to feel like a part of the special forces, how about giving this a shot?

Features & Specifications:

  • Material: Steel & Aluminum
  • Weight: 0.19 pounds
  • Type: Flip-up
  • Mounting type: Picatinny

Our Overall Verdict

Knight’s Armament is the Rolls-Royce of offset iron sights.

Yes, cheaper sights like Magpul can get the job done. BUT the detail, precision, and engineering of the Knight’s Armament add great value to the product.

  • When mounted on a rifle, it has a nice firm click that just exudes LUXURY.
  • Additionally, the rear sights aperture effortlessly guides your eye right down the hole on rotation.

And while most people think AR-15 offset is only for short-range targets, this sight might surprise you! This baby’s target acquisition can reach up to 300 yards!

7. Strike Industries Sidewinder – 45 Degree Offset Sight

Strike Industries Sidewinder - 45 Degree Offset Sight

BUYING OPTIONS:

» Check Price on Brownells «

Imagine reaping all the benefits of using Tactiton in a SMALLER and LIGHTER version. That’s Strike Industries’ offset iron sights for you. It might be tiny, but its features are mighty!

Features & Specifications:

  • Material: Aluminum
  • Weight: .12 lbs
  • Type: Flip-up
  • Mounting type: Picatinny

Our Overall Verdict

The Strike Industries Sidewinder got you covered in ALL your BUIS needs.

  • Flip them, and you’ll have 45-degree offset sights.
  • Remove the magnified optics, and you’ll get a traditional iron.
  • Fold them, and you’ll have canted iron sights.

45-degree, traditional iron, AND canted iron sights? That’s three backup sights in one!

The mounting plates are larger than usual, so your iron sights won’t get knocked off!

However, its ingenious design has some drawbacks.

As inline sights, they are canted from your tactical rifle. As a result, you need to cant your weapon. It makes windage adjustment to zero annoying.

But if you get to have a hang of it, these canted iron sights do a great job in target acquisition at under 50 yards.

8. Ozark Armament Backup Iron Sights

Ozark Armament Backup Iron Sights

BUYING OPTIONS:
» Check Price on Amazon «

This is another budget-friendly option for avid shooters or tactical enthusiasts strapped for cash!

Features & Specifications:

  • Material: Aluminum
  • Weight: 0.11 lbs
  • Type: Flip-up or fixed
  • Mounting type: Picatinny

Our Overall Verdict

So, what makes this sight popular?

  • Lightweight and durable
  • Maintains zero well 
  • Easy elevation and windage adjustment

But, just to set expectations, Ozark is not packaged in a wooden case like Tacticon. You’ll receive a basic kit with hex screws and an Allen wrench when you buy the product.

However, what it lacks in accouterments, it makes up by providing 2 versions of their sights: Flip-up and fixed. 

They have the SAME PRICE so you can choose whichever style you prefer.

These sights might not have a lot of fancy features, but if you’re on a tight budget and need something that REALLY works, you can check this out.

9. Feyachi Offset 45 Degree Iron Sights

Feyachi Offset 45 Degree Iron Sights

BUYING OPTIONS:

Feyachi is one of the top brands followed for its low profile and affordable price.

It is a great sight that won’t take much space on your rifle and interfere with your optics or accessories!

Features & Specifications:

  • Material: Aluminum
  • Weight: 0.11 lbs
  • Type: Flip-up
  • Mounting type: Picatinny, Weaver

Our Overall Verdict

Feyachi comes equipped with a spring-loaded flip-up feature.

  • With a simple press of the button, your offset iron sights will immediately POP!
  • You can quickly switch between your traditional iron and red dot sight picture.

It’s user-friendly, too. Unlike most other sights, Feyachi offers left and right-handed versions of BUIS.

Unfortunately, these sights don’t come with an instruction manual. If you’re new to this offset thing, you have to feel your way into setting this up.

But the good news is this sight is easy to install! We’re confident that you can still mount it in any rail mounting system of your choice.

10. Ade Advanced 45 Degree Offset Sights

If you are a beginner and you’re still playing with the idea of using iron sights to step up your game, how about trying Ade Advanced Offset Sights?

No frills, but it does what a BUIS intends to do!

Features & Specifications:

  • Material: Aluminum
  • Weight: 0.25 pounds
  • Type: Fixed Folding
  • Mounting type: Picatinny

Our Overall Verdict

It’s not like Knight’s Armament or Dueck Defense Rapid Transition Sight, but Ade gives a decent performance.

It has all the basic features you need.

  • It is made of aluminum, so you know it’s sturdy and lightweight.
  • It has a fully adjustable elevation and windage.
  • And most importantly, they look fine on your rifle!

What Are Offset Iron Sights for AR 15?

In 3-gun competitions, you may notice that the shooters tilt their rifles for certain shots.

No, they’re not doing that to look cool (well, maybe a little bit?).

In competitions, players cannot use regular iron sights because they have a scope or magnified optic mounted on their rifle for long-range shots.

So, what do they use for short-range shots? Yep, you guessed it right — offset iron sights!

They are mounted at the top of the rail and allow shooters to rapidly transition from long to short-range shots with just a fraction of time and effort by simply tilting the firearm at an angle of 45 degrees.

This is a HUGE ADVANTAGE in scenarios where time is of the essence!

Are Offset Iron Sights Better Than Inline Sights for AR 15?

Offset iron sights work like MAGIC for a close-range target.

Having iron sights over inline sights means that you don’t need to flip them up when needed. They’re too low profile, and they won’t interfere with your scope or red-dot sight.

The other advantage of offset over inline sights is it makes the rapid transition between short to long-range targets possible, and you don’t need to fiddle with your optic mount.

After all, you don’t have the luxury of time to take off your scope before engaging a target!

However, there’s a learning curve on getting used to offset sights compared to standard iron sights.

What to Look for in the Best Offset Iron Sights for Your AR 15

Voila! You’ve seen our favorite AR-15 offset sights.

Now, to help you narrow your choice, here are some things to consider when finding the best AR 15 offset iron sights!

#1 Fixed or Flip-up?

Fixed iron sights are INDESTRUCTIBLE, and their parts don’t move!

  • If you hate adjusting your sights, this might be for you.
  • Once set up, you don’t need to mess with them anymore!

But if you’re someone who doesn’t use your BUIS often and you prefer keeping them out unless needed (let’s say if you have a scope or red-dot on your rifle), then flip-up iron sights are better.

#2 Material

The most common material for sights is aluminum or steel.

There are many backup sights made of steel because it’s DURABLE and better for long-term use.

But, if weight is something you consider, aluminum-made sights are also not bad. They are also tough but lighter.

#3 Lock System

What if your flip-up iron sight touched a surface and folded IN THE MIDDLE OF A GAME?

Make sure that your sight has a tight lock system so you can keep up during fast-paced scenarios.

PRO TIP: If you are a 3-Gun competitor (or interested in becoming one), it would be best to pick a tool-free adjustment sight, so you fix the aiming problems in a jiffy!

Conclusion

That’s a wrap on the best offset iron sights for your AR 15!

Remember, offset iron sights are not for everyone. Trust us when we say that most offset sights will take some time before you get used to it.

But if you’re someone who needs to switch between short and long-range shots in a blink of an eye, then we’re sure you’ll love the thrill of offset irons!
