The Konus Pro F30 4x-16x52mm provides an affordable, precision, first Focal plane riflescope with a reticle as unique as the scope itself. An illuminated BDC reticle removes the guesswork of hold over angles at distances out to 550 yards regardless of the time of day. First Focal plane means the target-to-reticle ratio is maintained throughout all magnifications without point of impact shift. The exterior, one-piece 30mm hardened aluminum tube provides superior resolution and brightness. The windage and elevation controls are reset-table to zero, and incorporate a push/pull locking mechanism to avoid unwanted movement. The internal level bubble removes the possibility of canting. Developed to withstand the Recoil from many different caliber firearms, the F30 is excellent for hunting and target shooting. Includes flip up lens covers, a lens cleaning Cloth, and a 4" Sunshade.
