The Fullfield TAC30 Riflescopes Series offers a second-to-none close quarter battle (CQB) reticle for competitive shooters and law enforcement and military operators. The illuminated center dot and large, bright circle allow for instant target engagement at close distances. Holdover dots provide trajectory compensation out to 600 yards. 1x magnification allows for close-in, both-eyes-open shooting. 4x magnification allows engagement of mid-distance targets. The ultra-bright, illuminated reticles have a 10-position dimmer you can adjust for all lighting conditions.
