A Versatile Optic Built for Speed and Precision

When it comes to choosing a reliable optic for an AR-15, carbine, competition rifle, or defensive firearm setup, shooters need a sight that offers fast target acquisition, dependable performance, and the flexibility to adapt to different shooting situations. The Holosun HS510C Multi-Reticle Open Reflex Sight delivers all of these features in a rugged, lightweight package designed for modern shooters.

Available at Armax United, the Holosun HS510C combines advanced reticle technology, exceptional battery life, and durable construction to provide a versatile optic solution for recreational shooting, competition, training, hunting, and defensive applications.

Why Choose the Holosun HS510C?

A quality optic can make a significant difference in shooting performance. Traditional iron sights require more alignment and focus, while a red dot sight allows shooters to quickly acquire targets while maintaining awareness of their surroundings.

The Holosun HS510C is designed around speed and adaptability. Its open reflex design provides a wide sight picture, allowing shooters to engage targets quickly while offering multiple reticle options for different shooting scenarios.

Whether you're running drills at the range, competing in action shooting events, or upgrading your rifle setup, the HS510C provides the performance and reliability expected from a modern optic.

Holosun Multi-Reticle System (MRS)

One of the standout features of the HS510C is Holosun’s Multi-Reticle System (MRS). Instead of being limited to a single aiming point, shooters can select from three different reticle configurations:

• 2 MOA Dot – Ideal for precision aiming and longer-distance shots
• 65 MOA Circle – Provides rapid target acquisition for close-range shooting
• 65 MOA Circle with 2 MOA Dot – Combines speed and precision into one versatile aiming solution

This flexibility allows shooters to customize the optic based on their firearm, shooting style, and intended use.

For example, a competition shooter may prefer the circle-dot reticle for fast transitions between targets, while a shooter focused on precision may choose the smaller 2 MOA dot for more refined aiming.

Exceptional Battery Life With Solar Backup

One of the biggest advantages of the Holosun HS510C is its impressive battery efficiency. Powered by Holosun’s Super LED technology, the optic provides up to 50,000 hours of battery life, helping ensure dependable operation over long periods.

The HS510C also features Solar Failsafe™ technology, which allows the optic to utilize available ambient light as an additional power source. This provides an extra layer of reliability when battery power is limited.

Combined with efficient power management, the HS510C is built to stay ready when you need it.

Shake Awake™ Technology

The Holosun HS510C includes Shake Awake™ motion activation technology, designed to conserve battery life without sacrificing readiness.

When the optic remains motionless for a period of time, it enters sleep mode to preserve power. Once movement is detected, the optic instantly activates and returns to its previous brightness setting.

This feature makes the HS510C an excellent choice for defensive firearms and rifles that need to remain ready without constantly draining battery power.

Built for Real-World Use

A firearm optic needs to withstand recoil, weather, and demanding environments. The HS510C features a durable open-frame design that provides strength while maintaining a lightweight profile.

Its rugged construction makes it well suited for:

• AR-15 rifles
• Modern sporting rifles
• Tactical carbines
• Competition firearms
• Hunting rifles
• Defensive firearm setups

The open reflex design also provides a large viewing window, helping shooters maintain faster target acquisition compared to traditional tube-style optics.

Easy Installation With Quick-Detach Mount

The included quick-detach (QD) mount makes installation and removal simple while maintaining a secure attachment to your firearm.

The optic features a 1.41-inch height, providing a comfortable aiming position and compatibility with many popular rifle configurations, including setups that utilize backup iron sights.

Red or Green Reticle Options

The Holosun HS510C is available with both red and green reticle options, allowing shooters to choose the color that best fits their vision preferences and shooting environment.

Different lighting conditions, backgrounds, and personal preferences can impact reticle visibility, making color selection an important consideration when choosing an optic.
