Dose any one know if its a good one and also how much skill or how easy it is to assembly? Or should I just by a pre built upper?

This should get you through building an AR. GunTech : How to Build An AR-15 Video - World's Largest Supplier of Firearm Accessories, Gun Parts and Gunsmithing Tools - BROWNELLS

I don't know if that kit is good or not. Hopefully someone else can help you there.

NICE! I just bought a stripped lower the other day with the plans of building my own, since I have not been able to find any configured specifically like I want (partly because there are SO many options) and also because it's much easier to slowly accumulate parts "under the radar" than drop a big chunk of $$$ at once and try to explain to SWMBO. That link gives me one more place to start learning about what I'm getting myself into!

You need to get this book: "The AR-15 Complete Assembly Guide" by Kuleck and McKee. It has step by step directions plus pictures of everything and also warnings about the pitfalls you might run into. I started from knowing nothing and have built several ARs using this book. I can't recommend it highly enough. One thing to be aware of, you need a special wrench to put on the barrel nut and the butt stock nut and you need a torque wrench for the barrel nut. On top of that, you need a way to hold the upper receiver while you torque the barrel nut, usually an assembly block of some sort so you can clamp the upper in a vise while you torque the nut. I actually got a bar from Brownell's (I think it was them) that locks into the barrel lugs to hold the barrel while you torque the nut. These things add to your initial cost, but once you have them you can do anything you want with your AR.
