This guide will cover how to shoot with red dot sight. In addition, topics about posture, stance and recoil management are all essential elements to improve our shooting skills with a red dot.

The tips you will learn here applies to pistol, rifle and shotgun. 

Mastering Red Dot Sight

Getting good at using an optic is more than just point and shoot.

The main reason to use red dot sight is for faster target acquisition without aligning iron sights. 

This means:

  • Shooter can be 100% target focused
  • Provides CQB aiming solution to long range guns
  • Provides night time aiming solution
  • Shooter can aim with both eyes open to maximize situational awareness
  • No need to perfectly align sight picture
  • Faster target acquisition - Point of aim is point of impact (assume zeroed)

Pick The Right Dot Size

MOA dot size represents the reticle coverage area. Big dot can obscure smaller targets down range. Smaller dot can provide finer aiming point.

1 MOA and 2 MOA dot size are generally the best choices for rifle applications.

3 or 6 MOA dot sizes are generally for pistol and shotgun categories. 6 MOA is preferred for pistol usage. Much bigger dot, easier to see, better for astigmatism.

Shooting Posture and Speed

It's essential to understand that your vision controls your posture when shooting.

When we transition to a new target, what's the first thing that moves?

Your eyes! Because your body follows your eyes. Therefore, it's crucial to have good vision when shooting.

Consistent Stance

When shooting, it's crucial to have a consistent stance. You need to know why you do everything, including how you stand.

There's no one-size-fits-all stance, and we need to understand what works for us individually.

  • Isosceles stance is commonly used, but it's not always the best option
  • a fighter stance can be more effective than an isosceles stance when it comes to recoil control
  • A fighter stance is better in all four directions, whereas an isosceles stance is only good in two directions

Recoil Management

When it comes to recoil control, structure is better than strength. Shooters need to focus on posture and position when shooting to ensure that we're using structure instead of just gripping the gun super tight with muscle strength.

Loading the front quad can cause tension and impact our recoil management.

Instead, we need to focus on a balanced stance that allows us to absorb the recoil without relying on strength

Using Red Dot On Rifles

Using a red dot sight on a rifle is extremely easy.

Wherever the dot is placed, the bullet is going there (basic concept)

Most modern rifles feature standard pic rail to accept all types of optic mounts. The challenge most people run into is finding the right optic height.

1/3 cowitness and 1.93" tall optic mounts are the most popular right now.

The shooter can naturally bring up the rifle without having to put strain on their neck to see through the optic.

For NVG users, taller optic mounts provide enough room to work around.

Optic Zero Distance Matters

Different calibers yield different zeroing result. For most red dot users, the most preferred zero is the one that has the tightest group. This means the shooter doesn't have to think hard about holdover.

This is a 36 yard zero using standard 5.56 NATO 55gr ammo. Most shots land within a 8" circle between 5 to 100 yards.

Extend Red Dot Range

To extend the range of a red dot sight, simply mount a magnifier behind it like this: 

3X (Most popular), 4X or 6X

Using A Red Dot On Pistol

The most difficult part of shooing a pistol with red dot sight is sight picture acquisition where people struggle finding the dot. 

A pistol with a red dot means the shooter can focus on the target, keep both eyes open, and shoot accurately.

In traditional firearms training, we focus on a hard front sight focus, which can be counterintuitive. The red dot, on the other hand, goes where you're looking. This can be a good thing, but it can also feel weird if you're used to traditional iron sight focus.

Acquiring The Sight

There are many teachings out there on how to acquire the dot, and so far the best one is the four P system

  • Present - Presenting the gun
  • Prep - Preparing the trigger
  • Pinky - Use pinky pressure to drop the dot down from 12 o'clock position
  • Press - Shoot

Avoid punching out the gun, which can cause the shooter to miss the target or lose control of the gun. Instead, Isolating the number of moving axes to one, which can help to improve aim and reduce muscle tension and tremor.

Try Holosun 507C ACSS Vulcan Reticle

The ACSS Vulcan reticle helps guide the shooter's eye to find the reticle. The 250 MOA ring acts like an arrow indicator to help the shooter recenter the dot.

Other things to consider:

Grip Angle Matters

Did you know ? - Simply changing the grip angle just 1 - 2 degrees can help you align the optic window to the eye, and find the dot faster.

For High Tang Grip - Added back strap panel would help you offset that space around your thenar eminence hand muscle group, to angle the muzzle down a bit for better sight alignment.

Try Different Back Strap Panels

The grip panel slightly change the grip angle to fit your natural point of aim. 

Once you've found your sweet spot for gripping for a particular gun, you will notice a significant differences when acquiring the sight. 

Guns like Springfield XDM, Springfield Hellcat, FNX 45 Tactical, FN 509, 1911, Shadow System MR920L, Canik TP9sfx and many more all features adjustable backstraps for better grip to help you aim better with an optic.

Enlarged Window Optic Helps A Lot!

An enlarged window optic helps you can find the dot better, faster and never get lost in the window.

Try the center axis relock technique to bring the optic close to the eye while keeping 4 - 7" distance to prevent the slide from smacking into the shooter's face.

Control Your Draw Speed

Control your pistol draw speed appropriately will significantly avoid overshooting the optic sight picture.

Here is a tip - Pretend like there is a rubber band tension between your wrist and waist. As your arms extend the tension increases, thus slowing down the draw.

The slowing down the draw will give you that nice smooth sight picture acquisition.

Pistol Red Dot Co-Witness

Is pistol red dot co-witness important?

Yes it does, a tall front sight can help guide the eye to center the optic window to pick up the reticle right away without fishing for it.

Shooter Practice & Tweaks

Practice with the gun you have and get good at it! Eventually you will get used to the grip and find the dot faster.

Once you get enough shooting practice, you can quickly notice good grip feature on a gun that people don't practice may not notice.

Shooting On The Move

This one takes tons of practice - It's easy to shoot on a flat range while standing still, but when dynamic movement is introduced, all bets are off.

This requires a bit of foot work and breathing technique to keep the sight picture steady. You can practice this at home dry firing.

A cost effective way is to use an airsoft pistol with a red dot at home as many times as you like.

Cross Eye Dominance

It's not a problem if you're cross eye dominant when shooting a red dot equipped pistol. In fact, shooting with a red dot sight allows you to focus on the target plane with both eyes open.

Maintain proper grip, and then just shift your head to aim with your dominant eye.
