I have a green light to pick up another rifle and I always like the AR look so leaning toward that. I don't know much about the AR platform so if I screw this up please go easy on me. Here is what I need it for. The gun will be used at the range 90-100% of the time, I am thinking of coyote hunting so it might have double duty, and if the SHTF defense gun(not home defense got a shotgun for that). As I will be plinking at the range I sure I will buy one of the conversion kits so I can shoot .22. This will give my boys a chance to shoot it will me. I will be mounting a scope. I am not sure I can hit something at 300-400 yards but I am going to try(not with the .22 I know) as I hear the .223 can reach out to 500 yards. I know I want it to shoot .223 but the 5.56 while cool not a must. I hear some will shoot the 5.56 but not all. Name brand doesn't matter that much to me. Just want it to go bang when I pull the trigger and not brake the bank. So I am thinking about picking up a upper/lower then save for a bit and pick up the other. I am also pretty good with basic tools and mechanical inclined so if it saves me cash I will build it my self it that is a option. I really like the looks of the Zombie AR parts(I think spike makes them) and if I can buy only what I need to use with no extra parts it will save cash. My two boys and I are huge zombie fans so those zombie parts are pulling at my wallet even before I have anything to put them on. If you guys/gals can give me some info to point me in the right direction that would be great.
