AMMO ! Trust us they eat-em like they were skittles . Take your time and build the next one . I built an AR if bought in a store would cost 2k for half that . Take your time and let the deals come to you . You have one , go shoot it learn it understand what you like about it and what you think could be better for you and build that rifle .
Why do I carry a 45 ? because they don't make a 46
