Can anyone tell me the difference and the advantages between a russian, chinese, and a yugoslavian SKS. I went shooting a few weeks ago and shot a chinese sks. They are really fun to shoot. The ammo is also very cheap thats why i love it. Is it worth spending $150 for one a getting one of those synthetic sporter stocks from cabelas. It would be a good coyote gun if i practice with the open sights a little more. If anybody has been down this road before, letme know what you think. Thanks
