Scope sights are very popular among air gunners because a good scope helps to achieve maximum accuracy. In fact, a scope is the number one accessory an air gunner purchases. Walther Airgun Scopes are designed for airguns and feature ASR Technology to specifically handle the recoil shock unique to an air rifle where the first kick is rearward like a firearm, followed by an additional forward kick that is unique to an airgun. Firearm scope lenses are reinforced at the front to handle the rearward kick. The lenses on a Walther Airgun Scope are additionally reinforced at the rear to handle the second (forward) kick. ASR Technology protects the scope lenses from the unique recoil of an airgun. The Walther 4x32 Airgun Scope has a 1-inch tube with a Reticle 8 duplex. (These scopes and sights are designed for airgun use and are not intended for standard firearms.)
