From the manufacturer

This Primary Arms rifle scope is part of the SLx optics line. SLx optics built their 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 4-16x44mm first focal plane illuminated rifle scope combines one of the most popular magnification ranges for hunting with the features and innovations you'd expect from Primary Arms. At 4x magnification, the wide field of view and daylight bright reticle make tracking a moving target a breeze, while the top end's 16x magnification allows for unerring precision. The reticle is etched into the first focal plane. This means it is 'true' at every magnification, ensuring the ranging, holdovers, and wind holds can be used as long as you can see them. This 4-16x44mm SLx scope is equipped with the ACSS R Grid 2B reticle. A marked improvement over the original R Grid, the 2B retains fan favorites like the horseshoe and chevron for up close snap shooting at low magnification, as well as the incredibly handy auto-ranging system. The original line grid has been replaced with a 0.1 MIL dot matrix grid to reduce clutter and allow for more precise holdover references for a full 15 MILs below the center. For shooters who want the best reticle for extreme range shooting without sacrificing speed up close, look no further than the ACSS R Grid 2B, compatible with ANY caliber. The 4-16x44mm scope body is one of the 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 the fin's placement entirely at the operator's discretion. The improved turrets have tactile and audible 0.1 MIL click adjustments. The illumination turret offers eleven settings. A smooth parallax adjustment and fast focus eyepiece work together to provide a perfectly crisp image of the target and reticle.
