Tried a PSA 7.5 and the accuracy sucked. Now I have a lower that needs an upper. I dont mind building, though it would be my first upper. Money is tight. What are my options?

A 10/22. Badum-ching.
I will recommend my set up. Prices are approximate
Anderson lightweight sport upper receiver - $50-ish
CMMG heavy taper 16.1 inch barrel Optics Planet - $135
CMMG bolt and collar - Right to Bear Arms - $165
Knock off ambidextrous charge handle - Omega Manufacturing - $20
Thread protector - $6
A couple of S&W magazines - $40
Boonie Packer adapter or Catch-22 bolt catch and spacer - $40
Cheap free float tube - $30
$486 - I've built this upper twice, but with different handguards. Both shoot a bit less than 1.5moa with Aguila SV and an aluminium thread protector. (Groups get bigger with most muzzle devices).
CMMG also makes an M4 contour barrel I used to make a dedicated iron sight upper, but I think an optic only upper would be less expensive.
For less than that you can buy a 10/22 that will shoot 1moa. I still enjoy the AR22 though.
