Understanding the Design and Build
Holosun 509T
The Holosun 509T is a robust and compact enclosed reflex sight developed primarily for pistols, yet versatile enough for rifles. Constructed from durable titanium, the 509T is designed to withstand the rigors of field use. Its rugged design ensures resilience to physical shocks and adverse environmental conditions. The enclosed emitter design is particularly significant as it prevents debris, moisture, or dust from obstructing the view, enhancing reliability in all conditions.
One of the design highlights I appreciated is the multi-coated lens that enhances clarity and performance by minimizing glare and maximizing light transmission. During my time in the field, the robust design offered assurance that the optic could handle tough situations without losing zero.
Holosun 509T X2
Taking its predecessor’s design a step further, the Holosun 509T X2 maintains the full titanium construction while incorporating additional ergonomic improvements. The model addresses the button placement concern on the 509T by relocating them for more intuitive access. Despite appearing almost identical at first glance, the X2 version distinguishes itself with superior adjustability, allowing enhanced precision in settings adjustment on the go.
The updated battery compartment further augments user convenience, making changes seamless and keeping your optic functional with minimal hassle.
Performance and Features
Reticle Versatility
Both the Holosun 509T and the 509T X2 come equipped with the multi-reticle system, giving you the flexibility to toggle between a 2 MOA dot or a 32 MOA circle with a dot. This adaptability is perfect for different shooting scenarios, from rapid target acquisition to precision aiming for longer distances.
Battery and Solar Power
Battery longevity is a standout feature for both models with impressive battery life up to 50,000 hours on a single CR1632 lithium battery. Combined with the proprietary Solar Failsafe technology, these optics harness solar energy to extend battery life and ensure consistent performance even when battery power runs low.
In my experience, the solar power feature provided a seamless transition, especially during long shooting sessions in well-lit environments where electronic failures could mean the difference between success and failure.
Button Configuration
While the 509T houses its control buttons conveniently on the side, the 509T X2 further refines this design by positioning the controls beneath protective caps. This not only mitigates the risk of accidental presses but also streamlines handling. Personally, I found the X2’s button placement more intuitive, particularly when wearing gloves.
Optical Clarity and Window Size
A feature I particularly enjoyed is the expansive viewing window, which enhances rapid target acquisition while maintaining a wide field of view. Both models share a window size of 1.16 x 0.67 inches, crafted to maximize peripheral vision without compromising clarity.
Versatile Mounting
When it comes to mounting, both optics utilize the RMR footprint, making them broadly compatible with a variety of platforms. This standardization has been quite beneficial, allowing me to swap optics between firearms without the need for additional adapters.
