Scope Setup: Piggyback vs Offset Red Dot

Scope Setup: Piggyback vs Offset Red Dot

Choosing between a piggyback and an offset red dot scope setup is a strategic decision that significantly impacts your responsiveness and adaptability in the field. 

Whether navigating the complexities of a tactical situation or aiming for precision in competitive shooting, the right scope setup can be the defining factor in your performance. 

This guide covers the nuances of piggyback and offset red dot setups, helping you make an informed decision that enhances your shooting experience.

What Is a Piggyback Scope Setup?

The piggyback scope setup is a strategic configuration widely used among shooting enthusiasts for its versatility and adaptability. 

In this setup, a smaller, secondary optic, typically a red dot sight, is mounted directly on top of the primary magnified scope. This design allows for a quick transition between long-range precision and rapid, close-range targeting.


    • Versatility: The piggyback setup shines in its ability to handle diverse shooting distances. The shooter can engage in long-range precision shooting and, within moments, switch to close-range targeting without needing to adjust their equipment.
    • Night Vision Compatibility: For shooters using night vision goggles, the height of the piggyback setup is particularly advantageous. It aligns well with NVGs, providing an unobstructed view and seamless integration.
    • Ambidextrous Use: This setup offers significant benefits in tactical situations where shooting from either shoulder might be necessary. It provides flexibility and ease of use for both right and left-handed shooters.
    • Situational Awareness: Due to the vertical alignment, the piggyback setup allows shooters to maintain broader situational awareness, as they don't have to tilt their rifles and can keep their line of sight more aligned with the surrounding environment.
    • Target Acquisition: Many shooters will use a top-mounted red dot to quickly acquire the general location of a target at a distance and then simply lower their head to access the full capability of the magnified optic, getting them on target quicker than scanning through the magnified optic. 


  • Height Over Bore Issues: One significant challenge with the piggyback setup is the increased height of the red dot sight above the bore. This height can affect sighting at close range, requiring shooters to compensate for the difference in alignment between the sight and the barrel. While height over bore is a consideration for all optics when shooting at close range, piggyback setups have an especially high height over bore requiring shooters to hold entirely off the top edge of small targets.
  • Complexity in Use: Transitioning smoothly between the primary and secondary sights requires practice and skill. New users might find it challenging to quickly shift focus between different optics, especially under stress or in dynamic shooting situations.

What Is an Offset Scope Setup?

The offset red dot setup is another popular configuration for modern shooters, known for its quick target acquisition and ergonomic design. 

In this setup, a secondary red dot sight is mounted at an angle, usually 45 degrees, to the side of the primary magnified optic. This arrangement allows for swift transitions between different shooting distances.


  • Rapid Target Acquisition: The offset setup excels in situations requiring swift transitions between targets at different ranges. The minimal movement needed to switch from the primary to the secondary optic allows for quicker engagement of targets, particularly in close-quarters situations.
  • Ergonomics and Consistent Cheek Weld: The lateral tilt needed to align with the offset red dot is typically more ergonomic and intuitive. It allows the shooter to maintain a consistent cheek weld on the stock, which can benefit shot consistency and comfort.
  • Unobstructed Primary Optic: With the secondary optic mounted to the side, the primary scope’s sight picture remains unobstructed. This setup is helpful when the primary focus is on long-range targets, with the secondary optic used less frequently.


  • Risk of Damage and Snags: The offset red dot's protruding position makes it more vulnerable to damage from bumps and knocks. This aspect requires the shooter to be mindful of their environment and handling of the firearm.
  • Learning Curve and Adaptation: Some shooters may initially find the need to tilt the rifle to align with the offset red dot less natural. It requires practice and adaptation, especially for those accustomed to more traditional, vertically aligned setups.
  • Limited Use with Night Vision Goggles: Unlike the piggyback setup, the offset red dot is less conducive to use with night vision goggles, potentially limiting its utility in low-light conditions.
  • Non-Ambidextrous Use: While the piggyback setup is ambidextrous, the offset setup is generally optimized for either right or left-handed shooters and may not be as convenient for ambidextrous use.
  • Field of View Limitations: When using offset red dots mounted at the rear of the rifle, it may obstruct the peripheral field of view, which could be a disadvantage in certain tactical situations.

Which Setup Is Right for You?

Deciding between a piggyback and an offset red dot scope setup can be pivotal, influencing your shooting effectiveness and comfort. To determine which setup aligns best with your needs, consider the following factors:

Shooting Environment and Style

  • Piggyback: Ideal if you frequently switch between varying distances or require compatibility with night vision for low-light environments. It’s also great for maintaining broader situational awareness.
  • Offset Red Dot: Perfect for close-quarters combat scenarios or situations demanding rapid target acquisition. It's especially beneficial if you often engage in dynamic shooting activities that require quick reflexes.

Personal Comfort and Ergonomics

Consider which setup feels more natural and comfortable. The offset setup might be more intuitive if you prefer a consistent cheek weld, while the piggyback could be better if you're used to traditional, vertically aligned setups.

Versatility and Adaptability

If you value a setup that can handle a wide range of scenarios and is adaptable to both left and right-handed shooting, the piggyback might be the way to go.

Ease of Transition and Learning Curve

Assess your willingness to adapt to a new shooting method. The offset red dot might have a steeper learning curve if you're not accustomed to tilting your rifle.

Rifle Balance and Weight Considerations

Think about how each setup will affect your rifle's balance. The piggyback can make your rifle top-heavy, while the offset might offer a more balanced feel.

Long-Term Durability and Maintenance

Consider which setup aligns with your ability to maintain and protect your optics. The offset red dot could be more prone to snags and damage in rugged environments.

Refining Your Aim

Deciding between piggyback and offset red dot setups? It boils down to what works best for you. There's no one-size-fits-all answer here. 

Think about how you usually shoot, where you're using your gear, and what feels comfortable. Trust your instincts and go with the setup that feels right in your hands. Your ideal choice is the one that makes you feel confident and ready for whatever comes your way.
