In my last shipment of parts kits, I received a milled kit that is unlike any of the others I have on hand. The front milled stub is not the standard Yugo slab on the left side, this one is sculpted out and has an odd line on it, there is also a small screw in the side. The front sight block has larger side cut outs in it, and the bolt carrier is also different, on the bottom of the carrier where it rides over the mag the carrier is very narrow in this area. I could not find any markings on the stub to determined what it is, but it is not your standard M70. It also has a gas tube that is different. This one has 4 exhaust holes drilled in it, similar to a chinese rifle I saw once. This rifle is definately Yugo however. Due to the handguards and night sights. Does anyone know what model this kit is? thanks, Jim.
