Not terribly expensive and ammo is plentiful.
Some people on this board will flame me for wanting to consider a “commie gun,” but an AK doesn’t seem like too bad of an idea because of the take-down power, ruggedness, and the fact that they are dirt cheap. Of course, accuracy is shite.
What is the weight of this?
