1. Wheeler Delta Series AR Front Sight Tool - Overall Best AR-15 front sight tool

The Wheeler Delta Series AR Front Sight Tool is super affordable and gives you a lot of versatility in how you use it.

First, it has a hex head that can be used with a ¼ inch hex driver. And using a tool to turn your front sight makes things super easy.

However, it also has a key ring on the head that you can use as a handle for hand adjustment or removal. So it works, no matter where you are, in the garage or out in the field.

The finish is black zinc, which is a durable semi-matte finish that does a good job of resisting corrosion for long service life.

My only complaint with this tool is that it’s only compatible with 4-notch front sight posts. If you have a 5-notch front sight post, you’ll need a different tool.

Other than that, this is the front sight tool to get if you want both tool and hand adjustability or removal of your front sight.

Pros

  • Hex head can be used with a ¼ inch hex driver.
  • Key ring works as a handle for hand adjustment and front sight replacement.
  • Zinc finish looks good and prevents corrosion.

Cons

  • Only compatible with 4-notch front sight posts.

2. AIM Sports AR15/M16 A1 & A2 Front Sight Tool - Budget AR-15 Front Sight Tool

The AIM Sports AR15/M16 A1 & A2 Front Sight Tool gives you complete front sight post compatibility for the lowest price.

The main benefit of this front sight tool is that it’s compatible with both 4-notch and 5-notch front sight posts. So you can adjust any front sight post that doesn’t require a proprietary tool.

It’s got a wide, knurled body that makes it easy to adjust your front sight by hand. However, it’s not compatible with any tools. But your front sight should be hand-adjustable, anyway.

The construction is also impressively rugged for such a simple tool. This AIM Sports tool feels really heavy and dense for the size.

However, the finish is a bit thin. And this tool will be susceptible to rust once you’ve worn through the finish. So keep your tools dry.

Thin finish or not, this is still a hefty front sight tool that’s compatible with almost any front sight.

Pros

  • Compatible with both 4-notch and 5-notch front sights.
  • Thick, knurled body is easy to turn with your fingers.
  • Rugged steel construction.

Cons

  • Finish is a tad thin and leaves the tool susceptible to rust once it wears through.

3. Leapers New Gen UTG AR-15 Front Sight Combo Tool - Value AR-15 Front Sight Tool

The Leapers New Gen UTG AR-15 Front Sight Combo Tool is a simple and versatile front sight tool.

This tool is compatible with both 4-notch and 5-notch front sight posts. Which makes it compatible with any front sight post that doesn’t require a specialized tool.

It also uses a slightly longer body to give you plenty of knurled space for your fingers, even if your front sight has extra tall wings.

The finish is also thick and doesn’t wear off as easily as some other tools.

Unfortunately, the prongs on this Leapers tool seem thinner than the prongs of other tools. Though, it hasn’t been a durability issue. So maybe it’s not an issue.

But, overall, this is a really well-priced front sight tool that will handle any front sight adjustment or replacement you need to do.

Pros

  • Compatible with 4-notch and 5-notch front sight posts.
  • Longer body provides lots of knurled space for your fingers.
  • Thick, durable finish. 

Cons

  • Adjustment prongs seem thinner than some other tools, though it hasn’t been a durability issue so far.

The Blitzkrieg Components AR-15 Universal A2 Front Sight Tool is a cost-efficient option for anyone who only needs a front sight adjustment tool that will adjust 4-notch front sight posts.

No, it’s not compatible with 5-notch front sight posts. But if you only have 4-notch posts, it works perfectly.

The design is super simple. But the grip surface works well. And it’s easy to turn your front sight post with just a thumb and finger.

Also, the finish is relatively thick and holds up well, even if you let this tool bang around in a tool kit or range bag.

Simple? Check.

Durable? Check.

Affordable? Check.

That’s it. This Blitzkrieg Components is a solid tool for those who have 4-notch front sight posts and don’t want to bother with tools for anything else.

Pros

  • Compatible with 4-notch front sight posts.
  • Simple design with nice grip texture that makes it easy to adjust or remove your front sight post with a thumb and finger.
  • Durable finish that holds up to a lot of abuse.

Cons

  • Not compatible with 5-notch front sight posts.

5. Troy BattleSight Adjustment Tool - AR-15 Battle Sight Adjustment Tool

Troy Industries is known for producing rugged equipment. And the Troy BattleSight Adjustment Tool is just as rugged and durable as their other products.

It should be noted that this tool comes with the Troy Folding Front BattleSight. So you’ll have one more tool than you need if you buy it separately.

But this sight is well-built from the same steel that Troy uses for their other AR-15 components. And the finish is thick and durable to prevent rust and corrosion for a long time.

However, the nice thing about his tool is that the prongs are shaped so that it fits the adjustment disc of many rear battle sights, including the Troy Folding Rear BattleSight.

So it’s an all-purpose backup sight adjustment tool, which is more useful than you might think, since many folding backup sights don’t have hand-adjustable windage.

Lastly, the body is long and gives you lots of knurled surface to grip while you’re adjusting your sights.

If you have rear sights that also require a tool for adjusting the windage, this Troy Industries tool is an excellent option.

Pros

  • Durable steel construction with a thick finish that lasts for a long time.
  • Compatible with 4-notch front sight posts.
  • Works for adjusting rear sights that have no hand-adjustable windage knob.
  • Long body provides lots of knurled surface for your fingers.

Cons

  • Not compatible with 5-notch front sight posts.

6. Sun Optics AR Front Sight Tool - Lightweight AR-15 A1/A2 Front Sight Adjustment Tool

The Sun Optics AR Front Sight Adjustment Tool is a capable front sight adjustment tool that’s also even lighter than your average front sight tool.

The main thing is that this front sight tool is made of aluminum. So it’s only 1 ounce, maybe less. So you won’t even notice you’ve got it until you need it.

Yes, aluminum is a bit less durable than steel. However, it won’t rust. And it’s tough enough for adjusting or removing an AR-15 front sight post.

It’s also got a well-designed body that leaves plenty of knurled area for your fingers.

And the finish is thick and durable. It stays black even when you’ve got it banging around in a tool bag.

So, if you want a front sight adjustment tool that practically disappears when you don’t need it, this Sun Optics tool is for you.

Pros

  • Super lightweight.
  • Aluminum construction won’t rust.
  • Lots of knurled area for gripping with your fingers.
  • Thick, durable finish.

Cons

  • Not compatible with 5-notch front sight posts.

7. Barska Front Sight Adjustment Tool - Universal AR-15 Front Sight Tool

The Barska Front Sight Adjustment Tool is an excellent option for those who need to adjust both 4-notch and 5-notch front sight posts.

In addition to being compatible with any front sight post that doesn’t require a proprietary tool, this tool also works with any fixed sight or flip up sight. So it’s good for both classic sights and backup sights.

Also, this tool is constructed from carbon steel, which is quite hard and tough. So it’ll last a lifetime.

Then, this tool is a bit longer than many other tools, at 2.5 inches long. This tool is super easy to use for hand-adjustment.

Lastly, the finish is thick and doesn’t wear off easily, which keeps this Barska tool rust free for a long time.

It does take up a bit more space than some other tools. But that adds a lot of comfort and ease of use. So it’s a nice tool if you value comfort.

Pros

  • Compatible with any sort of front sight—4-notch, 5-notch, fixed, flip-up, anything.
  • Carbon steel construction is remarkably hard and tough.
  • 2.5-inch body provides plenty of grip space.
  • Thick, durable finish lasts a long time to prevent rust for as long as you own this tool.

Cons

  • A bit larger than some other tools.

8. Doublestar Front Sight Combo Tool - Ergonomic AR-15 Front Sight Tool

The Doublestar Front Sight Combo Tool is both versatile and goes the extra mile for comfort and ease of use.

This front sight removal tool is compatible with both 4-notch and 5-notch AR-15 front sight posts. Use it on any front sight post that doesn’t require a proprietary tool.

However, it features a thick middle section with a knurled surface that’s easy to grip between your fingers. This makes it easier and more comfortable to adjust or remove your front sight post.

Also, the finish is surprisingly nice. It’s about the same as what you’d find on a standard AR-15 part. So it holds up and prevents rust for a very long time.

And preventing rust is important. Because this front sight tool is made of steel.

It might seem trivial (and maybe it is), but the shape of this DoubleStar tool makes it a bit awkward to store. Most front sight tools are basically just a stick. But this one is like a little ball bearing with pegs on it. So it can be tough to find a good place to store it, if you’re extremely organized.

But that’s a minor thing that normal people probably won’t even notice. Overall, this is an excellent tool that’s super easy and comfortable to use.

Pros

  • Thick body makes it very easy to grip with your fingers and adjust or remove your front sight.
  • Compatible with both 4-notch and 5-notch front sight posts.
  • Thick, durable finish protects the steel construction from rust for a long time.

Cons

  • Heavy and can be awkward to store.

9. KNS Precision AR-15/AK47 Combination Front Sight Tool - AR-15 Front Sight Removal Tool

The KNS Precision AR-15/AK47 Combination Front Sight Tool is all about leverage. So it’s a great tool for front sight removal and replacement.

The big deal with this tool is that it has a t-handle that makes it easy to install or remove your front sight post, even if it’s really stubborn.

And it works with any 4-notch AR-15 or AK47 front sight post. And it’s long enough to reach down into front sights with taller wings. So you can use it on multiple types of rifle.

It’s also made of steel for long-term durability. However, this KNS Precision tool is plain steel without a protective finish. So it could rust if you’re not careful.

However, the t-handle design really takes the cake, especially if you’re a gunsmith or hobbyist who needs to remove and install a lot of front sight posts.

Pros

  • T-handle makes it easy to remove and install even the most stubborn front sight posts.
  • Works with both AR-15 and AK47 4-notch front sight posts.
  • Durable steel construction.

Cons

  • Not compatible with 5-notch front sight posts.
  • Steel is not coated to prevent rust.
