When choosing a red dot for a compact striker-fired pistol or MOS-equipped slide, durability and sight picture clarity matter most. A sight that holds up to everyday carry, offers quick target acquisition, and remains intuitive under stress delivers real defensive value.
VIRIDIAN RFX45 (GLOCK MOS) steps into that role with a closed emitter design and a wider rectangular window that improves situational awareness. Shop this product

Key features that matter on the range and in carry
The RFX45 features a 24 x 15.5 mm rectangular window that gives a noticeably wider field of view than many micro red dots. Its closed emitter design keeps the LED protected from impacts and environmental exposure, enhancing long-term durability. Viridian’s bright 5 MOA green LED is easier to pick up in varied light compared to traditional red dots, which can speed target acquisition in defensive scenarios.
Battery life and illumination control
Ten illumination settings (eight for day, two for night) let you tailor brightness to ambient conditions. The sight runs up to 50,000 hours on a single CR2032 battery — one CR2032 is included in the package, along with a sight adjustment tool and a Glock MOS adapter plate to simplify installation. At $349.00, it competes well on performance-per-dollar in the red dot market. View product details and pricing
Compatibility and mounting
The RFX45 uses an Aimpoint ACRO footprint and ships with a Glock MOS adapter plate, making it an excellent option for shooters who want a direct-fit solution for MOS slides without extensive gunsmithing. The all-black finish keeps reflections minimal and matches a wide range of pistols and accessories.
For shooters prioritizing fast sight acquisition, robust emitter protection, and long battery life in a compact package, the VIRIDIAN RFX45 (GLOCK MOS) is a focused choice. Check current availability on the shop page to confirm stock and compatible mounting options. Check availability
