Building your first AR has the distinct potential to be an unrewarding process. How would you know what to build if you have no experience with the platform? The choices can be dizzying. You'd know nothing about the quality of the various parts, nor the functionality that you could expect from different configurations. There is occasionally the assumption by some people that "parts is parts". That is most definitely not true. Parts are available that range from Chinese imports to meticulously machined. It's a tricky landscape. IMHO, you'll waste a lot of money building your first AR since you have no experience with the platform.
First thing you need to do IMHO is define in your mind what you want to do with the rifle. Long range hunting? Home defense? Target? Training? Range toy? Just something to show off to your buddies? The answer to those questions will determine configuration (stock, rail, optic, sights, barrel, trigger, grip, barrel length, sling attachment, light attachment, flash suppressor vs compensator). That decision also helps to define your cost. If you're just going to put a couple of hundred rounds through it a year busting dirt clods, a consumer-grade $650 AR may be all you need. i.e. "good enough". If your need has more emphasis on reliability, or if you're the kind of guy that takes pride in owning high-quality firearms, you'll be looking at more money.
I'm not from around there, so I know nothing about Atomic Tactical. From what I read and hear, however, ThunderJohn here on this forum sounds like a really good face-to-face go-to guy and THAT is where I'd start if I lived where you do.
My recommendations for your first AR would be something from BCM, or perhaps better - a Colt 6920. That latter rifle typically goes for around $1000, and represents the lowest cost point of entry into the realm of high quality ARs. If you don't need or want high-quality, you could get by in the $650 price range.
