Hey just thought I would tell you all a little about myself. I'm 18 and I live in Sioux City, IA. I haven't had much shooting experience. Guns I have shot so far are shotguns, ak47, xd45, bunch of 22's, and a few long rifles of smaller caliber. I just turned 18 so I am looking into purchasing/building my first gun, which will be an AR. Plan on joining the Marines once I finish college. You won't be seeing many technical posts from me since I am just here to read and learn, but I do appreciate the information you guys post here and hopefully I'll be able to answer questions after I learn some more.
