Riton has a first focal plane scope to let you use the Mil-Dot markings at any power to check the range, estimate size or adjust for windage without changing your scope settings for a quick shot if needed or to make sure that trophy is the one you really want. Riton lets you see a better spectrum of color in the scope with High Density (HD)/Extra Dispersion (ED) glass and with the fully multi coating lenses means better performance early and late just in case that one you have been waiting for steps out. The scope is dry Argon purged and sealed to prevent internal fogging because you can not hit your target if you can not see the target. Stay ahead of the game with Riton. Riton was started in 2013 in Tucson Arizona to bring affordable quality optics to the industry. The first years where spent primarily on research and devolvement with testing done by hunters and Tier 1 operatives to make sure the scopes would stand up to what the word could demand.
