It's been 20 years since I had an ar, (used to have a Colt). Now I'm finding myself longing for it back... but I'm poorer than I was then, so now I'm looking into putting one together. That said, are kits the way to go for a semi-noob in the ar arena? I don't think I know enough to get the right parts individually or not, but I'm fairly certain I'm smart enough to do the job if I have all the parts. If so, are there some kits better or worse than others?
