Kensight gun sights are utilized as original equipment by many leading manufacturers today. The Kensight M1 Carbine rifle rear sight is fully adjustable for both windage and elevation, serving as a contemporary recreation of the original WWII-era milled adjustable rear sight. It combines an authentic appearance with superior functionality. The rear sight body is precision-machined using Wire-EDM from 4140 chrome moly steel, which is subsequently heat-treated to a hardness of RC 38-40. It features precise click adjustments for windage, ensuring reliable and consistent changes in the point of impact. Elevation adjustments are made by sliding the peep aperture ramp forward or backward to engage one of four distinct detent positions, marked "1," "2," "2.5," and "3," indicating the range to the target. This modern, high-quality reproduction of the original rear sight is patterned exactly after the factory M1 Carbine rear rifle sight using advanced CAD/CAM design techniques, facilitating the restoration of your M1 Carbine to an authentic appearance.
