Just spent my spoon money on teh father's day deals from Palmetto State Armory...
But checking today, it seems that you can get a complete AR-15 for $310 plus whatever your local enabler charges for a FFL transfer...
Complete upper for $160 - free shipping -
https://palmettostatearmory.com/psa-16-carbine-length-5-56-nato-1-7-m4-nitride-moe-upper-with-rear-mbus-bcg-ch.html
Lower build kit - $110 - everything but the lower receiver -
https://palmettostatearmory.com/a2-rifle-build-kit.html
PSA bare lower - $40 -
https://palmettostatearmory.com/psa-stealth-lower.html
Free shipping on all 3, so $310 plus transfer fee and a few hours to put all the parts together.
I really don't need another... but dang... tempting!
