OK, I'm thinking of buying an AK-47. There's one at a local gun shop that I have my eye on. It's one of the models with a wood stock, made by Century arms i believe. The price seems right ($350) but it's about a hundred bucks less than all the other ones they have (all the other ones are folding stock models). Can anyone tell my what to look for and what to avoid when buying an AK? and does anyone know why the folding stock ones are all more expensive than the wooden stock ones?
