Please go easy on me (new guy to ARs)
I heard this was a good site to learn about AR15s. I'm looking to get or build my first one. I'll be honest I don't know a lot about AR's or guns (I have a basic understanding of them and how they work) but I do build motors for my hobby so I was thinking about assembling my own one. I will be modding the snot out of it anyways because I can't leave it alone so I figure I might want to build one. I know BCM is a badass company and I love the idea of having their chrome lined 1:7 16" upper so I was thinking of going with this...

Now what I DON'T know is the difference in the 16" ones they offer.

After these parts I would need a complete lower and I would be good to go right?
