So which would be better than for a free float barrel?
The profile relates to how much weight you want out front.
How much total weight you want.
How many rounds it can fire before heat effects accuracy.
How many rounds it can fire rapidly before permanent damage.
Typically you see heavy. Government. And m4 profiles on general purpose builds.
Someone linked this video series that Brownells did and I found it incredibly educating. And it was effing cool too. My first build I put together a stripped lower and bought a complete upper. My second build might be a custom upper too, we'll see. Check it out, even if you don't use it for a reference, it'll show you the general process. They also have purchasing checklists and the lists of tools you need (some may be extraneous, but it'll give you an idea).

Good luck. I agree with everyone else, it's all about having fun. Be safe.
One thing to think about - I doubt anyone here would disagree...
Instead of trying to get everything you need/want on one rifle, realize this is a disease and you're likely to end up building another upper if not an entire rifle at some point. So for example, build up a good 16" carbine M4 setup the first time and shoot it up and enjoy it. Then figure you're going to want to put together a 20" govt profile setup at some point for "long range" or whatever. If you're unlucky, you'll get bit by the NFA bug and decide you can't live without a 10.5 or 12.5 short barreled upper too, with a noveske pig - or eventually a suppressor. Maybe a slide fire stock or a 22lr conversion kit (or a 22 upper). Plus now that you have 3-4 uppers, someone's going to point you to a sale on stripped lowers, so you might as well build up the lowers to match all those guns, too. And then you'll have several rifles, a box of leftover parts that you'll be trying to sell/trade on the boards just like the rest of us, and you'll be eating ramen because you can't afford steak anymore.
LOL - really though, my only point is not to stress over it too much. Most guys when they build their first rifle spend a ton of time stressing over the parts. I'm betting everyone has been in your shoes at some point. The good thing about the AR platform is you can always switch it out, and you're likely to keep messing with it as you go anyway.Pick a good set up, or copy someone's and get shooting. SAVE SOME MONEY FOR AMMO - it's still stupid expensive. Lots of good advice here and on other boards, but nothing will be as good as your own personal impressions and needs once you get to shooting your gun.
Hah the sad part about this is, I could see that exact situation happening to me. I guess I just wanna make sure that for my first build I'm buying quality parts so that it will be a long lasting gun. Like you said though, I'll probably make more and keep messing with them and switching things out. I really appreciate all the help I've gotten from everyone on here, I didn't think a gun forum wouldv'e been so welcoming haha
Which is where all the FOR SALE: used / take off tubes, bbls, optics, f/hiders etc are wallowing. Someones great build idea 2 months ago is for sale today.
Put a list together of your ideal build, then one for a basic shoot and go from there build. If not the trading post section, i have boxes of take offs collecting dust. Almost Free AMIGO, almost free

I joined several sites before I found this one. In almost every occasion I was mocked for my ignorance when I asked questions. When I joined COAR I was afraid I'd get more of the same thing. I was relieved and pleasantly surprised when I found out this place has a different breed of membership - people who really enjoy the sport & want to help others. As you can see from my post count, I dived in head first and haven't looked back. I love this community!

Some musings.
I have been doing a lot of reading on audiophile forms lately. The best advice I've seen is "define what you want and stick to it".
What kind of AR-15 do you want? Home defense, range gun, plinker, competition, hunting, ultra light, handy, hood ornament...?
Have you had any time behind a "stock" AR-15? That might be a place to start. Figure out what works for you and what doesn't.
Don't get too caught up in the "best" parts. There are a lot of quality mid-grade parts that will work just fine.
