From the manufacturer

This rifle scope is part of our SLx optics line. SLx optics built our reputation for innovation, reliability and value. All SLx optics undergo rigorous field-testing during development to best serve you in any environment. The Primary Arms 3-18x50mm first focal plane illuminated rifle scope punches far outside of its weight class. At 3x magnification, fast snap shots at close range are a breeze with the daylight bright illuminated reticle, but the scope easily allows shooters to reach the 1,000 yard line when cranked up to the full 18x available at the top end. To make the best of the reticle at every magnification, it has been etched into the first focal plane. This allows it to be 'true' at every magnification, allowing the ranging, hold overs, and wind holds to be used as long as you can see them. Features: First Focal Plane reticle is true at every magnification Full reticle illumination is daylight bright Chevron tip central aiming point provides infinitely small aiming point The replaceable power ring fin can be positioned to user preference Locking, Zero resettable turrets 30mm main tube Weight: 25.4 oz. with battery, without lens caps Water proof, fog resistant, shock resistant Lifetime warranty The 3-18x50mm scope body is our most advanced to date, offering new innovative features, as well as old favorites. A removable and replaceable fin on the power ring allows for rapid adjustment of the magnification range just like a magnification lever, with placement of the fin entirely at the discretion of the operator. The improved turrets have tactile and audible 0.1 MIL click adjustments, as well as offering easy reset once you've got your zero and secure locking to prevent accidental adjustments. The illumination turret offers six settings with an 'OFF' setting between each for fast switching to your preferred setting. A smooth parallax adjustment and fast focus eye piece work together to provide a perfectly crisp image of the target and reticle. Featuring clear glass, forgiving eye relief/exit pupil characteristics, and efficient industrial design, the 3-18x50 FFP Scope is backed up by the Primary Arms Lifetime Warranty.
