You’ve had your AR-15 for a while now, and although the A2 front sight has done its job, it’s time for an upgrade. Luckily for you, it’s an easy piece to remove without having to visit your local gunsmith.

It might seem hard, but all it takes is 4 easy steps to remove an AR-15 front sight:

  1. First, remove the handguard
  2. Then, remove the upper half
  3. Third, remove the flash hider and gas tube
  4. Finally, remove the front sight

Pull up a chair, grab some safety goggles, and I’ll walk you through step by step on how your AR-15 front sight removal (images included).

Let’s get started!

Step 1: Removing the Handguards

Most AR-15s have a stock two-piece handguard that needs to be removed in order to get the front sight off.

HANDGUARDS REMOVAL (2)

This is arguably the most difficult step in the process if you don’t have the right tools for the job.

HANDGUARDS REMOVAL (3)

Luckily, you can get a specially designed handguard removal tool for a low price that will make everything so much easier.

Once you’ve got your tool, you’re going to place the hooks into the mag well and the arms through the delta ring.

From there, you’ll pull the arms back toward the rear of the rifle.

This compresses the spring and lets you slide the handguard off.

Step 2: Removing the Upper Half

Now, you’ll need to grab your vise and secure the upper half of your AR-15 in it.

HANDGUARDS REMOVAL (1)

To do that, you’ll need to remove it from the lower part of your AR and detach any optics, rear sights, or carry handles that you’ve installed.

UPPER AND LOWER HALF REMOVAL

I highly recommend grabbing this vise block to protect both your vise and your firearm from getting dinged up in the process.

Once you’ve removed any add-ons, take the bolt carrier and charging handle out from the inside of the upper half.

Then it’s finally time to place the upper half into your vise and make sure that it’s secure.

Step 3: Removing the Flash Hider & Gas Tube

From there, it’s time to grab a wrench and start unscrewing the flash hider, which you’ll find attached with a cupped washer.

FLASH HIDER REMOVAL

It’s easy to find, but you’ll need to use a lot of force to get the washer to let go of the flash hider.

FLASH HIDER REMOVAL (1)

While any wrench will do the job eventually, I prefer using an armorer’s wrench that’s designed for it.

No products found.

Once it’s free, the only thing left to remove is the gas tube.

GAS TUBE REMOVAL

I recommend using a brass hammer or a roll pin punch for this part so that you don’t accidentally damage or deform the gas tube roll pin holding the tube in place.

GAS TUBE REMOVAL (1)

You remove the taper pins by simply punching it out from the case that’s holding it. It’s best to use a taper pin starter punch

AR FRONT SIGHT REMOVAL (2)

Once again you’ll need to use a lot of force, but try not to break the taper pins.

TAPER PIN REMOVAL

When it’s out you’ll notice that the gas tube is free and that it’s easy to easily remove and set aside.

TAPER PIN REMOVAL (1)

You might also need to remove the gas block, which can double as a sight block for some. The gas block is just as simple to take off.

TAPER PIN REMOVAL

By removing the taper pins the same way as with the gas tube, you’ll make room for a new gas block and maybe even more rail space for your front sight.

GAS TUBE REMOVAL

Depending on the purpose of your front sight, you might want a low-profile gas block.

Step 4: Removing the Front Sight Itself

Once all of the gas block taper pins are removed, all that’s left is to remove the front sight itself.

APPLYING PENETRATING OIL

Depending on how worn the rifle is it could be as easy as twisting the front sight and pulling it off, or you could need to use a mallet to give it some light taps to the front sight pins before it comes free.

AR FRONT SIGHT REMOVAL (1)

The important thing to remember is to be careful and to take your time in removing each piece so that you don’t damage any part of your rifle.

AR FRONT SIGHT REMOVAL (2)

Otherwise, it could be difficult to put in that low-profile gas block.

If anything up until now has seemed confusing, like taking off the gas block with a taper pin punch or maybe replacing a barrel nut, then check out this youtube video:

AR 15 Front Sight Removal Conclusion

Now that you’ve managed to get the gas block and boring A2 front sight off of your AR-15, it’s time for a new one.

These are some of the top AR-15 scopes that I recommend.
