The long eye relief, locking diopter, and fully multi-coated lenses are just a few of the reasons the Iron Peak riflescope will be a crowd pleasing favorite. Tough construction and bright images are just the icing on the cake. Its hard anodized single-piece aircraft-grade aluminum tube is nitrogen-purged and o-ring sealed for waterproof/fogproof/weatherproof performance.
