Viridian RFX42 Compact Enclosed Emitter Green Dot Optic

Viridian Weapon Technologies raises the bar in firearm optics with the debut of the RFX42. This compact, enclosed-emitter reflex sight has been engineered specifically for modern optics-ready concealed carry pistols. The RFX42 brings rugged reliability, compact dimensions and Viridian’s proven green dot technology to shooters demanding fast target acquisition in any condition.

Engineered with a Shield RMSc footprint, the RFX42 is compatible with a wide range of popular slimline handguns. Its enclosed design offers maximum durability and protection against dirt, moisture and debris. It is ideal for EDC and duty use alike.

The 3.5 MOA green dot is crisp and highly visible in all lighting. It even comes with 10 brightness settings (including two night-vision compatible levels). Featuring the Viridian patented Instant-On technology, the optic activates with motion and powers down automatically after inactivity. This extends the battery life up to 28,000 hours on a single CR1620 cell.

“Shooters have been asking for a rugged, enclosed, compact optic that doesn’t sacrifice clarity or speed—and the RFX42 delivers,” said Brian Hedeen, Viridian President and CEO. “It’s built to thrive on carry guns and perform under pressure, with premium features that competitors just aren’t offering at this size or price point.”

Weighing less than 1 ounce and housed in durable aluminum with an IPX6 waterproof rating, the RFX42 is built for real-world use without the bulk of other enclosed optics.
