First AR15 build... Help with parts list!?

Diesel,

You are aware that by going to a 14.5" Barrel it becomes a Short Barrel Rifle according to ATF rule and requires registration and a $200 Federal Tax Stamp. Once an SBR always an SBR. The exception is for example if you would have the 14.5" Barrel with a Vortex Flash Hider permanently affixed to the barrel. (Pinned & Brazed).
My suggestion unless you have the proper tools like a torque wrench, barrel nut tool, receiver block, head space gauges and etc. I would just buy a complete upper with the bolt carrier group already in it. This will also assure everything is correct.

Well said! That's exactly what I ended up doing. Originally, I planned on building the upper because I thought it would be cheaper but found out if you don't have all the tools for the job then it will actually end up costing more after factoring in the cost of the tools + parts (at least it did in my case). Luckily I was able to find a complete upper with all the parts I had on my list except for the bcm bcg. but a noveske bcg should do just fine. I'm happy I bought the upper complete because you don't wanna do a poor job at assembling the upper and mess up the headspacing, accuracy, etc. just build the lower its a lot easier unless you really know what ur doing and already have all the tools. Good luck!

Thanks guys I have been doing some research and decided to listen to you guys and buy a complete upper already assemble to avoid error. Now if I get a standard 16" upper will I have to get that federal stamp? Any suggestions for uppers?

No, not with 16". Check your local regs though. Read through recent threads for upper selection. And have you read the AR primer sticky?

You can still get a 14.5" barrel but you will need the flash hider pinned and welded to get you to the 16" legal length , this will not require a stamp either .
