How to Mount a Red Dot on a Shotgun: A Comprehensive Guide

Shotguns are versatile firearms used for various purposes, including hunting, home defense, and sport shooting. Learning how to mount a red dot sight on your shotgun can significantly enhance your shotgun’s performance, improving target acquisition and accuracy.

In this comprehensive guide, we will cover the steps to mount a red dot sight on your shotgun, from selecting the right sight to proper installation and maintenance. So, let’s dive right in!

Types of Red Dot Sights

There are two primary types of red dot sights suitable for mounting on a shotgun:

Tube-style Red Dot Sights

Tube-style red dot sights resemble traditional rifle scopes, featuring a cylindrical design with a lens at both ends. These sights provide a more focused field of view and often come with multiple brightness settings to suit different lighting conditions.

Reflex-style Red Dot Sights

Reflex-style sights, also known as open sights, have a more compact design with a single lens. They offer a wider field of view and are typically lighter than tube-style sights. Reflex sights are popular choices for shotguns due to their lightweight and easy target acquisition.

Choosing the Right Red Dot Sight for Your Shotgun

Before purchasing a red dot sight, consider factors such as your intended use, personal preferences, and budget. Test out various models to find the one that feels most comfortable and intuitive for you. Look for features such as adjustable brightness settings, compatibility with your shotgun model, and a durable build quality to withstand recoil and harsh environments.

Understanding Mounting Options for Red Dot Sights on Shotguns

When it comes to mounting a red dot sight on your shotgun, it’s essential to understand the different mounting options available. Some of the common mounting options include:

Receiver Mount

This type of mount attaches directly to the shotgun’s receiver, providing a stable platform for the red dot sight. Receiver mounts may require drilling and tapping to ensure a secure fit. Consult the manufacturer’s guidelines to determine if your shotgun is compatible with a receiver-mounted red dot sight.

Saddle Mount

A saddle mount straddles the shotgun’s receiver and attaches using existing pins or screws. This option is non-invasive and does not require any modifications to your shotgun.

Barrel Clamp Mount

This type of mount clamps onto the shotgun’s barrel, providing a platform for the red dot sight. It’s a suitable option for shotguns without a pre-drilled receiver or for those who want to avoid making permanent modifications to their firearm.

Rail Mount

Rail mounts, such as Picatinny or Weaver rails, provide a versatile platform for mounting various accessories, including red dot sights. Some shotguns come with a pre-installed rail, while others may require an aftermarket rail to be attached.

Preparing for Installation

Before starting the installation process, gather the necessary tools and materials:

  • A compatible mounting platform
  • Screwdrivers or Allen wrenches
  • Loctite or a similar thread-locking compound
  • A cleaning cloth and gun cleaning solution

Choose the appropriate mounting option for your shotgun and red dot sight, ensuring compatibility and stability.

Step-by-Step Guide: How to Mount a Red Dot Sight on Your Shotgun

Follow these steps to mount your red dot sight on your shotgun:

Step 1: Unload and Clean Your Shotgun

Before starting any work on your shotgun, always ensure it is unloaded and safe to handle. Remove any ammunition from the chamber and magazine. Clean the mounting area on your shotgun using a cloth and a gun cleaning solution to ensure a secure and stable fit.

Attach the mounting platform (e.g., receiver mount, saddle mount, barrel clamp mount, or rail) to your shotgun following the manufacturer’s instructions. Apply a small amount of Loctite or a similar thread-locking compound to the screws to prevent them from loosening during use. Ensure that the platform is properly aligned and level.

Step 3: Attach the Red Dot Sight to the Platform

Once the red dot sight is in the desired position, tighten the screws or clamps to secure it in place. Be careful not to overtighten, as this may cause damage to the sight or mounting platform. Apply a small amount of Loctite to the screws to prevent them from loosening over time.

Step 5: Test for Stability

Gently shake your shotgun to ensure the red dot sight and mounting platform are securely attached. If you notice any movement or wobbling, re-tighten the screws as needed.

Step 6: Zero in Your Red Dot Sight

Take your shotgun to a safe shooting range to zero in the red dot sight. Follow the sight’s instructions to adjust the elevation and windage settings for accurate targeting. You may need to fire several shots and make minor adjustments to achieve optimal accuracy.

Red Dot Sight Battery Considerations

Red dot sights often rely on batteries for power. To avoid being caught off guard by a dead battery, keep the following tips in mind:

  • Use high-quality batteries from reputable brands to ensure longevity and reliability.
  • Always carry spare batteries when you plan to use your shotgun for an extended period.
  • Periodically check the battery life and replace the batteries as needed, especially before important outings like hunting trips or competitions.

Tips for Proper Maintenance and Care

To ensure your red dot sight maintains peak performance, follow these maintenance tips:

  • Clean the lens regularly using a soft, lint-free cloth and a lens cleaning solution.
  • Check the screws and mounting platform periodically for signs of wear or loosening.
  • Replace the batteries as needed and always carry spare batteries in case of unexpected failure.
  • Store your shotgun and red dot sight in a cool, dry place to prevent damage from moisture and temperature changes.

Safety Tips When Using a Red Dot Sight on Your Shotgun

When using a red dot sight, safety should always be your top priority. Keep these safety tips in mind:

  • Always treat your shotgun as if it were loaded, even when you know it’s not.
  • Keep your finger off the trigger until you’re ready to shoot.
  • Never point your shotgun at anything you don’t intend to shoot.
  • Be aware of your target and what’s beyond it, ensuring a clear line of sight before firing.
  • Use proper hearing and eye protection when shooting to avoid injury.


Mounting a red dot sight on your shotgun can greatly improve your shooting experience, providing faster target acquisition and increased accuracy. By selecting the right sight, understanding the mounting options, following the proper installation steps, and maintaining your equipment, you can ensure a successful and enjoyable experience with your shotgun and red dot sight combination. Always prioritize safety and proper care to guarantee the longevity and optimal performance of your shotgun and red dot sight.
