Viridian RFX Green Dot Reflex Sight 3 MOA - Compact Carry Optic

Our review of the Viridian RFX is aimed at concealed carry owners and shooters who want a compact, highly visible green dot sight that does not add bulk. The bottom line: the RFX delivers a very visible 3 MOA green dot in an ultra-light package with convenient INSTANT-ON and auto shut-off features, making it a strong choice for optics-cut pistols and close-range offset use. Reviewers who prioritize dot visibility and quick target acquisition will find the RFX especially appealing.

Key Features

• Green 3 MOA dot: The green aiming point is designed for maximum visibility across varied lighting, helping faster target acquisition.
• INSTANT-ON and auto shut-off: The sight powers up quickly when needed and conserves battery with automatic shut-off for long run times.
• Lightweight design: At a mere 4 ounces, the RFX is one of the lightest reflex sights and preserves the balance of a concealed carry pistol.
• Versatile mounting: Includes a Picatinny mount and supports Shield RMSc, Docter and RMR style footprints for broad compatibility.
• Windage and elevation adjustments: Intuitive controls allow straightforward zeroing and reliable point-of-impact tuning.
• Long battery life: An ambient light sensor and efficient electronics yield over 30k hours of run time under typical conditions.

Who It's For

The RFX is best for owners of optics-cut concealed carry pistols who need a compact sight that prioritizes quick target acquisition and low weight. It also suits shooters who want a close-range offset sight on rifles or a simple, minimal footprint optic for duty use.

Those who should look elsewhere include buyers wanting multi-color reticles, extreme waterproof ratings not mentioned here, or an integrated magnifier system; the RFX is a purpose-built reflex sight focused on a single, highly visible green dot and compact form factor.
