What is the HOLOSUN - 507C X3 OPEN PISTOL REFLEX SIGHT?

HOLOSUN 507C X3 OPEN PISTOL REFLEX SIGHT

The Holosun HS507C-X3-RD-MRS updates the proven 507C platform with a reinforced housing, advanced brightness control, and Holosun’s Multi-Reticle System in a compact optic built for modern pistols. Designed around the RMR footprint, it delivers a low-profile solution that works just as well for everyday carry as it does for duty and range use. A forward-facing photodiode pairs with Solar Failsafe to automatically manage brightness as light changes, while manual controls with memory and lockout give shooters full authority when needed. Powered by a side-loading CR1632 battery rated up to 100,000 hours and backed by Shake Awake, IP67 waterproofing, and 5000G vibration resistance, the HS507C-X3-RD-MRS blends versatility, durability, and smart power management into one no-nonsense pistol optic.

Great inventory
The Holosun 507 GR X3 is an awesome red dot on my Springfield echelon 4.0C. The green radical is more visible for me in all conditions, including bright sunlight. And Brownells has pretty much all of the red dots you could want for any firearm in stock. Great service, Fast shipping, What more can you ask for. Thanks Joezey
