The best thing you can do is educate yourself by reading everything on as many AR15 forums as you can. Take your time. There are so many threads about "I bought X when if I had known I would have bought an Y or the Z".
Not just you, but many, get on a forum and ask "what's best" and end up more confused than when they started. Ask a question and you'll get 1000 different opinions.
