The Yugo is pretty hideous. It is as long and about as heavy as an M1. Still, I'd leave it alone.
My son has one. It eats my Russian SKS for lunch off the bench. 2-inch 5-shot groups versus 4 1/2-inch 5 shot groups at 100 yards. The Yugo's trigger is quite decent. The Russian's trigger takes two men and a boy to pull.
