The Bushnell Forge riflescopes all have an 8x zoom range and a very thin 4A reticle with light point. ED lenses ensure optimal sharpness all the way to the edges, and Fully Multi-Coated Optics and the Bushnell Ultra Wide Band Coating ensure that you can keep looking into the last daylight. The Forge riflescopes are waterproof and also feature the new Exo™ Barrier dirt- and moisture-resistant coating, so you can still see a clear and bright image in the worst conditions. The field of view at 1x magnification is a whopping 37.3 meters. The tube diameter for ring mounting is 34mm.
