If you can get an AR-15 for $400, let me know I'll take 10..... Personally Id go for a Ruger LCP for pocket concealed carry, or a Kel-Tec P3AT which is basically the same thing only about $100 cheaper. Whatever is left should go for ammo.

Trade it for an AR-15, they are fun guns to plink with, can be used to protect your home and even hunt with given the proper ammo. The gun grabbers are coming soon..........
