Gunbroker, cheap shit is the pumpy and single shot, try going to milsurp or some gunshop if you can find any, just look it up on Google, like fuck my city even has a gun shop at walmart, don't get a cheap rifle no matter the price, likely theyd be 22lr which are like high powered airsoft thats meant for rabbits and shooting practice. With shotguns, even if they're shit and cheap and just break, it's not like you're gonna use it twice. https://www.gunbroker.com/item/786531920
The only thing with gunbroker is that you need to ship it to an feel liscensed place, usually an arms dealer. Though I wouldnt reccomend suicide, at least try the military due to all the benifits, just lie about depression and you'll find somewhere were you belong, because they choose the best job for you.
