The PLxC 1-8x FFP Compact Rifle Scope now features RDB (Red Dot Bright) diffractive reticle technology. This unique design is much more efficient than traditional etch-and-fill reticles delivering red dot brightness without compromising battery life all while still utilizing a first focal plane reticle. The more efficient and brighter illumination is further improved by the use of AutoLive technology that helps to conserve battery life and ensures your reticle is visible the moment you need it.
