Much like Snake Eyes, I am a ninja who is not opposed to guns.
Buying a rifle outright is a bit out of my economical means, so I recently ordered a "blemished" Spike's lower from JoeBobOutfitter.com and I will build it as I can afford parts. I'll probably get a CMMG .22LR upper as ammo is cheaper and the smaller handgun only ranges will let me shoot there. I'll get a "real" 5.56 upper as well when I find something I like. There's a handgun range very close to where I live, so that's a HUGE factor in my decision.
Don't look for anything fancy. I sucked with the M16-A2 when I was in the Army, so I want as close to an A2 as I can get, iron sights and all, just to prove to myself I can hit something with it. I've shot a friend's rifle and wasn't nearly as terrible as I used to be. Also, I'd like to get a bayonet on it. Damn nostalgia.
I got a "Punisher" lower. More details to come.
