Holosun HS507C X3

• Multi-Reticle System: The selectable 2 MOA dot, 32 MOA circle, or combined circle-dot setup lets the sight adapt to different shooting tasks, from precise aiming on small targets to faster acquisition at close range.
• RMR Footprint Compatibility: Built around the Trijicon RMR standard, the HS507C X3 fits a wide range of pistol slides and mounting plates, making it easier to integrate into existing handgun or carbine setups.
• Long Battery Runtime: With up to 100000 h of battery life from a CR1632 cell, the sight reduces battery changes and supports a dependable always-ready setup for carry or range use.
• Compact Open Reflex Design: At 67.00 g and with a 16x23 mm window, this reflex sight keeps the handgun trim while still giving a clear viewing area for quick dot pickup.
• Rugged Aluminum Housing: The aluminum body with waterproof, fogproof, and shockproof construction helps the sight stay functional in rain, temperature changes, and repeated recoil.

About the Holosun Reflex Series

Holosun Reflex sights cover the company’s open reflex designs for both pistols and long guns, with the family expanding from the 510C in 2016 to the 507 and 508 series in 2017. Within that lineup, the 507 series is centered on compact open reflex sights intended primarily for pistol use, where low mounting height, fast sight picture acquisition, and practical carry dimensions matter most. A defining feature of the series is Holosun’s Multi-Reticle System, which gives the shooter a choice of a 2 MOA dot, a 32 MOA circle, or a combined circle-dot pattern depending on speed and precision needs.

The series is also known for integrating Solar Failsafe and Shake Awake, technologies that support practical field use rather than adding complexity. Solar assistance and automatic wake functions help preserve battery life while keeping the optic ready for defensive, sporting, or training use. Across the family, the design philosophy stays consistent: compact open-emitter sights with straightforward controls, proven mounting standards, and reticle options that suit both close-range speed and more deliberate shot placement. That makes the Holosun Reflex line especially relevant for modern handgun optics, but also for carbine and shotgun applications where a lightweight reflex sight is preferred.

About the Holosun HS507C X3

The Holosun HS507C X3 is a 1x open reflex sight built for shooters who want a compact optic that works equally well on a pistol slide or on a lightweight long-gun setup using the Trijicon RMR footprint. Its compact dimensions of 45.00 mm in length and a weight of 67.00 g keep the sight from adding unnecessary bulk, which matters on reciprocating pistol slides and on fast-handling carbines alike. The 16x23 mm window gives a practical balance between a low-profile housing and a viewing area that supports quick dot acquisition during presentation.

The sight’s Multi reticle configuration is one of its main strengths. A 2.00 MOA aiming point supports more precise placement, while the larger circle-based options help the eye pick up the reticle faster at shorter distances. Because the reticle is illuminated with adjustable intensity and an intensity switch, the sight can be tuned for indoor ranges, bright daylight, or changing backgrounds. The stated parallax freedom from 25 meters supports natural target focus and fast shooting with both eyes open, which is exactly where a reflex sight offers its biggest practical advantage.

Mechanically, the HS507C X3 uses 1 MOA click adjustments with 30.00 MOA of windage and 30.00 MOA of elevation, giving enough adjustment range for typical pistol zeroing and many offset or compact rifle applications. The aluminum housing, combined with waterproof, fogproof, and shockproof construction, is suited to regular carry, training, and recoil exposure. Power comes from a CR1632 battery with a rated runtime of 100000.00 h, which supports long service intervals and makes the optic practical for users who prefer to leave the sight ready for immediate use.
