What is Glock Rear Sight?

The rear sight is a device on the weapons that are used for aiming while shooting. These are available at the backside of the gun slide. These rear sights are adjustable. It helps to position and lock aim in the target with front sight’s coordination.

A Glock Rear Sight serves the same purpose as in other guns. It helps in easy aiming at the target. These rear sights are accessible to position, and you can adjust them according to your shooting style. Unlike many rear sights, they are made up of plastic or other materials and are lightweight and easy to use.

How to install Glock Rear Sight?

 It is an old-school yet efficient method for installing rear sight in a Glock.

All you need is:

  • A nylon punch
  • Hammer
  • Nut driver 3/16 size
  • Bench Mount
  • Loctite/ thread locker
  • Nylon jaws
  • Filer
  • New Glock sights

First of all, disassemble the gun and by checking if there are no bullets or magazines present. After checking, please take out your slide and remove the spring and barrel from it.

When you turn your slide, you will see a small screw inside attached to the front sight. With the help of a 3/16 nut driver, unscrew and remove the old front sight. Replace and install the new one with the same method. Add some Loctite in the screw for better adherence. Make sure your front sight is aligned.

Coming to the rear sight, place your slide in the bench mount between nylon jaws. Using nylon punch, gently hammer the rear sight sideways to remove it. You can also use brass punches, but they will leave some marks on the Glock.

After removing the old sight, place the new one on the place while making sure it’s correctly faced. Push it in the space if it goes one-third without any resistance; it’s a good fit. But if it doesn’t, file the dovetails in one direction a few times and then check it’s fitting.

After becoming a great fit, hammer it through the nylon punch to reach its desired position. Add some Loctite or thread locker and screw from the top with Allen key.

In this way, your rear sight is perfectly installed at home.

Guide to adjust Glock Rear Sight

Here’s how to adjust Glock Rear Sight in different ways. 

Standard rear sight

The primary sight adjustment is that the front and rear sight head should be equal when aiming. Also, the front sight should be in between the rear sight while leaving some side spaces. This allows uniform aim under any circumstances. Also, you can adjust the rear sight that complements your shooting style.

For a central position of the rear sight, place the depth gauge of the Vernier caliper on both sides of the rearview and measure their depth. The depths should be equal on both sides. If they’re not, hammer the side with through nylon punch to adjust the rear sight.

Sight pusher method

There’s a sight pusher that comes for the Glock Rear Sight adjustment method. Although it is expensive, it seems pretty easier to use. Here’s how to use it

Disassemble and change the front sight as the process mentioned in the installation process

At the pusher base, there’s a plate that fits the Glock slide to prevent movement. Adjust it on the plate. You’ll see that your rear sight is between the two holds. Rotate the handle to adjust the rear sight or install the new one in the same way.

Adjustable rear sight

In an adjustable rear sight, there come two adjustments, height and side-to-side alignment. In rear sight, two screws like adjusters are present that are operated with a specific key that comes with the rear sight.

The screw present on the behind is used to revamp the height. So when you rotate it with its key, your rear blade will elevate or depress. Along with height moderation, the screw placed more forward is used to control the side-by-side adjustment.
