of South African military or police columns by attempting to disable the lead vehicle with an M60, either targeting the engine block or the wheels. By the end of the war, each PLAN section included at least one insurgent armed with an M59/66, and another with an RPG-7. Larger PLAN units included an equal number of insurgents armed with M59/66s and RPGs, with each carrying at least three rifle grenades or five PG-7 projectiles, respectively. Description The Zastava M59/66 PAP is identical in function and operation to the Soviet SKS in nearly every respect, except its ability to launch 22mm rifle grenades from an integral grenade launcher spigot mounted at the front of the barrel. The rifle has been fitted with a folding ladder sight for use in launching grenades. This sight is normally locked into a folded position atop the gas block. Prior to firing a rifle grenade, the sight is unlocked by depressing a switch on the gas port. This action also closes off the gas port in the barrel, which prevents the semi-automatic action from being cycled while a grenade is being launched. The sight ladder may then be raised and locked into the vertical position. The M59/66 was fitted with an unusual bayonet mount which also doubled as the mount for the front sight and the folding grenade launcher sight. The original Soviet blade bayonet as standard to the SKS had to be replaced by a unique Yugoslav bayonet to accommodate the new mount placement. A commercial variant of the M59 and M59/66 series, available for sale to civilians in some of the post-Yugoslav republics, lacked the bayonet or the ability to fire rifle grenades.
