Get what looks good! I think 18 and 20" look nice n secsi expecially with the longer 12"+ forearms.
My advise is to buy a stripped lower asap. Then start sourcing ur parts.
If you are unsure of what you want, the best thing I've found is to get to a gun show. Pickup and handle as many ars as possible. Get ur grubby paws on as many as you can. It'll really help you when you do. There's only so much reading and looking will do for you!
