The HK G36 5.56x45mm rifle was designed in the early 1990s as a replacement for the heavier 7.62mm G3 battle rifle. This genuine rimfire replica, manufactured exclusively by Walther under license from HK, offers all the excitement of the original in cost effective .22 LR caliber. Like the original G36 Walther's tactical model has a folding stock for easy transport and storage. The raised picatinny top rail provides a platform for a scope or other aiming device. The external safety is ambidextrous and the rear sight is adjustable for both windage and elevation.
