well i see you posted this in MAy but it seems to be active

you cannot get an "AK47" for $400. its a MAC90

get the AR-15


Ammunition is MUCH cheaper because there is a lot of it around

7.62x39 ammo is drying up and it getting really expensive


also.... better learn to reload.... itll save you a lot of money.... but i guess that depends on how much you shoot
