Finally, an affordable, precision, first focal plane riflescope with a reticle as unique as the scope itself. An illuminated, 1/2 mil-dot reticle affords precise shooting at long distance regardless of the time of day. The engraved "quick-peep" center cross-hair removes any chance of the reticle covering your target. First focal plane means the target-to-reticle ratio is maintained throughout all magnifications without point of impact shift. The exterior, one-piece 30mm hardened aluminum tube provides superior resolution and brightness. The windage and elevation controls are resettable to zero, and incorporate a push/pull locking mechanism to avoid unwanted movement. The unique, built-in level bubble removes canting at long range and helps perfectly mount the scope atop your gun for improved accuracy. Developed to withstand the recoil from just about any caliber firearm, the F30 is perfect for every tactical, hunting, and target/bench rest shooter. The 6X-24X50 has a side parallax wheel from 10 yards to infinity. The 1/2 mil-dot reticle can be illuminated in traditional red, or an amazing blue. This is fantastic when shooting in dark conditions or into dark targets. The 1/10 mil adjustment coincides perfectly with the mil-dot reticle.
