i know this might be a problem question but i need some help on an ak purchase. i have read alot on the durability and dependability of these rifles and in these trying times i think that might be something to get. i am familar with the .30 cal it shoots [owned a mini 30 for a while]. i just don't know what i need to look for. i don't want junk for sure or anything close, i also don't want something that needs upgrades. there is a gunshow in our area this weekend so i'll start to look there. i am familar with most defense pistols and rifles but not the ak. thank you in advance for any help.
