The KonusPro M-30 is truly the ideal riflescope with more features than any other scope in the market. The one-piece 30mm aluminum tube provides superior resolution and brightness. It has a mid-sized parallax wheel, adjustable down to 10 yards; locking tactical turrets resettable to zero; and a 45-degree offset illuminator switch with five intensities. Waterproof, fogproof, and shockproof, the M-30 is nitrogen-filled with fully multi-coated optics, a locking fast focus ocular, and a level bubble. The 1/10 mil adjustments perfectly coincide with the mil-dot reticle for accurate shooting at any range. It includes flip-up covers and a sunshade. This model is a 10-40x52mm with an engraved dual illuminated Mil-Dot reticle, and a matte black finish. It includes a CR2032 battery.
