Just a suggestion, lots of other options.
Build or buy a complete lower of your choice & put a PSA (Palmetto State Armory) or BCM (Bravo Company) complete upper on it.
PSA & Primary Arms have sales on both on a regular basis & both are decent sources.
Anything BCM is top notch.
Doing the above will get you into a completed gun for $1,000-1200, less if you hit the right sale, & it will be a very decent piece.
MM
And a lot of PSA's parts, like the barrel, are made by FN.
