Viridian RFX 45 Features The Viridian Weapon Technologies RFX 45 uses a closed emitter design which routes the sight picture through an enclosed tunnel rather than an open window. This construction gives shooters faster aiming point acquisition than a traditional open reflex sight and also shields the emitter from dust debris and impact damage that can disrupt an open design in the field. The 5 MOA green dot reticle is bright and precise enough for quick target transitions and the sight offers 10 total brightness settings including 8 daylight levels and 2 dedicated night vision settings. A full 90 MOA of windage and elevation adjustment gives plenty of room to zero the RFX 45 accurately on a wide variety of pistol and rifle platforms. Built from machined 6061 aluminum with a hard coat anodized finish the RFX 45 is engineered to handle the recoil and daily wear that comes with duty and range use. The housing carries an IPX6 environmental rating and an operating range of negative 4 to 130 degrees Fahrenheit so the sight keeps functioning through rain heat and cold alike. INSTANT-ON technology activates the optic the instant it senses motion and automatically shuts down after two minutes of inactivity conserving the single CR2032 battery for a rated 50 000 plus hours of runtime. The RFX 45 mounts to the ACRO footprint and ships complete with a high Picatinny mount for 1/3 co-witness along with mounting hardware making it a ready to install dependable green dot optic for sale at GrabAGun.
