these are the type of 10 round single stack mags that come with Romanian WASR-10 rifles when they are imported. After the guns get here they are modified by machining out the mag well to accept the wider standard 30 round mags and these are no longer required. They also add some US made parts to the gun at that time to keep things legal. The 10 round mags are generally valueless after that point, very few guns require this mag, but back in the good old days they sold the single stack guns for about $100 less than the hi-cap guns and those low-cap guns are still floating around here and there. I'm not sure why they even ship these mags in with the guns
