Viridian RFX45 Features The Viridian RFX45 centers its performance on a 5 MOA green dot reticle that stays visible in bright daylight while remaining fine enough for precise work at distance. The push button INSTANT-ON switch wakes the sight immediately with no warmup and 8 daylight plus 2 night vision brightness settings let the shooter match the dot intensity to the lighting conditions of the moment. Unlimited eye relief means the sight can be mounted at whatever distance suits the host slide without losing the dot which speeds up target transitions in a defensive or competitive setting. A total windage and elevation adjustment range of 90 MOA delivered in 1 MOA clicks gives plenty of room to zero the RFX45 precisely on a wide range of handguns. Housed in machined 6061 aluminum with a hard coat anodized finish the RFX45 is built to shrug off the knocks and holster wear that a daily carry or duty optic takes on. An IPX6 waterproof rating and an operating range of negative 4 to 130 degrees Fahrenheit mean the sight keeps functioning through rain humidity and temperature swings most shooters will actually encounter. The ACRO and Docter footprint mounting pattern included in the box along with the mounting hardware and a CR2032 battery lets it drop straight onto a wide range of optics ready pistols. At 1.73 oz and powered for up to 50 000 hours on a single battery the Viridian RFX45 is a low-maintenance duty-ready green dot sight for sale at GrabAGun.
