Untitled document Every feature was put in place for one purpose: to help you get the maximum peformance from your long-range firearms, at the range, hunting, or in a tactical environment. - The Leupold® Index Matched Lens System® delivers superior resolution from edge to edge of the visual field – even at 25x – along with peak image brightness and optimal contrast. - Side focus parallax adjustment for fast, easy parallax focusing from 75 yards to infinity, from any shooting position. - M1 windage and elevation adjustment dials with audible, tactile 1-MOA clicks. - 60-MOA each of windage and elevation adjustment range. - The reticle magnifies the reticle along with the image, so you can estimate range at any magnification setting. - Available with the Mil Dot or Tactical Milling Reticle (TMR™). - These reticles are ideal in tactical situations, but also provide greater accuracy of range estimation for hunters and target shooters. - The 30mm maintube offers incredible strength and allows for the greater range of windage and elevation adjustment. - Flip-open lens covers are standard issue with the Mark 4® ER/T riflescope. - Durable, subdued matte black finish. - Rugged and absolutely waterproof, the ER/T is built to Leupold Mark 4 standards, and can withstand incredible abuse.
