Finding the best piggyback red dot sight can significantly improve your shooting accuracy, speed, and versatility. Whether you’re using a precision rifle, a competition setup, or a tactical firearm, a piggyback red dot allows for quick target acquisition without having to switch optics or change positions. This type of setup is especially popular among shooters who use magnified scopes but still want the option of engaging close-range targets efficiently. In this topic, we’ll explore what makes a piggyback red dot valuable, the features to look for, and some of the most trusted options available today.
Understanding Piggyback Red Dot Sights
A piggyback red dot is a small reflex sight mounted on top of another optic, typically a riflescope. The idea behind this configuration is to give the shooter two aiming systems in one setup one for long-range precision and another for fast, close-range shooting. This is especially beneficial for hunters, 3-gun competitors, or tactical users who encounter targets at varying distances.
Instead of tilting the rifle or changing optics, the shooter simply adjusts their head position slightly to use the red dot mounted on top of the primary scope. The combination saves valuable time during transitions and helps maintain situational awareness.
Why Use a Piggyback Red Dot?
Using a piggyback red dot offers several practical advantages, making it a preferred setup for many shooters
- Rapid Target AcquisitionThe red dot allows for quick sight alignment at close distances where using a magnified scope would be too slow.
- VersatilityA piggyback red dot makes your firearm adaptable for multiple shooting scenarios whether long-range or close-quarters.
- Space EfficiencyIt eliminates the need for an additional mounting system or switching between optics during shooting.
- Improved Accuracy in Dynamic EnvironmentsIn hunting or tactical situations, a piggyback red dot provides an instant aiming reference for fast-moving targets.
Key Features to Consider
Choosing the best piggyback red dot involves evaluating several factors that influence performance, durability, and compatibility. Below are some essential considerations
1. Size and Weight
A piggyback red dot should be compact and lightweight to maintain the balance of your firearm. Bulky optics can interfere with your sight picture or make your rifle top-heavy. Micro red dots like the Trijicon RMR or Holosun 507C are excellent examples of compact, high-performance designs.
2. Mounting Compatibility
Ensure the red dot you choose fits the mount of your primary optic. Many modern scopes, such as those from Vortex, Leupold, and Nightforce, come with pre-drilled mounts for RMR-style footprints. Some shooters use 45-degree offset mounts instead, depending on personal preference and optic height.
3. Reticle Clarity
A crisp and visible reticle is crucial for quick targeting. Most piggyback red dots use a 2 MOA or 3 MOA dot, providing a good balance between speed and precision. Adjustable brightness settings are important for adapting to lighting conditions, from bright daylight to dim indoor ranges.
4. Battery Life and Power Options
Battery longevity is a key factor. Look for red dots that offer thousands of hours of runtime or feature motion-activated systems that preserve battery life when not in use. Solar-assisted models, such as the Holosun series, add reliability in field conditions.
5. Durability and Weather Resistance
Since a piggyback red dot sits exposed on top of your optic, it must withstand recoil, dust, moisture, and temperature changes. Choose models made with aircraft-grade aluminum, shockproof housings, and IP-rated waterproofing to ensure consistent performance.
6. Ease of Zeroing
Look for a red dot with simple windage and elevation adjustments. Having clear and tactile clicks allows you to zero the sight accurately without hassle, even in the field.
Top Piggyback Red Dot Options
Below are some of the best piggyback red dot sights known for their reliability, clarity, and build quality. Each of these models is widely used among shooters and professionals who require dependable optics for their firearms.
1. Trijicon RMR Type 2
The Trijicon RMR Type 2 is one of the most popular choices for piggyback configurations. Known for its rugged construction and exceptional clarity, it features adjustable LED brightness and a battery life of up to four years. The RMR’s housing is designed to absorb impact, making it ideal for heavy recoil rifles or tactical setups. Its low profile and standard footprint make it compatible with most scope mounts.
2. Holosun 507C X2
The Holosun 507C X2 offers a combination of affordability and advanced features. It includes a solar panel and a long-lasting battery with up to 50,000 hours of runtime. One standout feature is its Multi-Reticle System (MRS), allowing users to switch between a 2 MOA dot, a 32 MOA circle, or both. This versatility makes it suitable for both precision and rapid-fire applications.
3. Leupold DeltaPoint Pro
Leupold’s DeltaPoint Pro is another excellent choice, offering a wide field of view and crystal-clear glass. It’s slightly larger than some competitors but provides unmatched visibility and durability. Its motion sensor technology automatically activates the sight when it detects movement, preserving battery life while ensuring readiness.
4. Aimpoint ACRO P-2
The Aimpoint ACRO P-2 is known for its enclosed emitter design, protecting the lens from dirt, rain, and debris making it perfect for rugged environments. It delivers over five years of continuous use on a single battery and offers precise 3.5 MOA dot illumination. This sight is a favorite among military and law enforcement users who value reliability above all else.
5. SIG Sauer Romeo Zero Elite
Designed with polymer housing and high-definition optics, the SIG Romeo Zero Elite provides excellent performance for shooters looking for a lightweight, cost-effective option. It features multiple brightness settings and uses a Shield RMSc footprint, which is compatible with various micro mounts.
Mounting a Piggyback Red Dot
Installing a piggyback red dot requires a proper mount that ensures alignment and stability. Most shooters attach the sight directly to the top of the main scope’s body or ring. Many scope manufacturers offer dedicated mounts specifically designed for red dot attachments. Alternatively, 45-degree offset mounts can position the red dot slightly to the side, allowing quick transitions by tilting the rifle.
When mounting, it’s essential to ensure that the red dot sits securely and maintains zero even after recoil. Using thread locker on screws and confirming torque specifications according to the manufacturer’s guidelines can help prevent shifting or misalignment.
Maintenance and Calibration Tips
Maintaining your piggyback red dot ensures consistent performance. Clean the lens regularly using microfiber cloths to remove smudges and debris. Check the battery periodically and replace it before critical use. If your red dot has motion activation, verify that it functions correctly during storage and transport.
Zeroing the red dot properly is also crucial. A good practice is to zero at 25 or 50 yards for short-range accuracy while maintaining usability for mid-range engagements. This configuration complements the long-range scope setup without overlap.
Choosing the best piggyback red dot depends on your specific shooting style, firearm type, and budget. Whether you prioritize ruggedness, battery life, or optical clarity, options like the Trijicon RMR, Holosun 507C, and Leupold DeltaPoint Pro remain top-tier choices. A piggyback red dot not only enhances your versatility but also provides a tactical advantage in scenarios where speed and accuracy are critical. Investing in a high-quality sight ensures you can transition seamlessly between long and short distances, keeping your aim steady and your confidence high on every shot.
