Yugo m70 dummy grenade. It's the same dimensions as the built in Yugo SKS launcher. Grenade model is an inert novelty model prop dummy grenade with exact exterier deminsions and shape. I amtrying to find a dummy grenade for a yugo m70ab and the blanks to fire it. It is much smaller diameter where it mounts on the spigot. These are a must have for any display! Training grenades will have some mud and dirt on them from use on our lane at Thunder on the Tundra. Description This is an original accessory for the YUGO M70 series AK rifles but will fit onto any left hand threaded AK muzzle. A non-corrosive PPU 7. 62x39mm blank is supplied with each M60 Chalk Rifle Grenade and refill shot. Upgrade your M70 rifle with authentic military-grade hardware.
