Selling AR-15 upper

I'm replacing the HBAR complete upper on my rifle for an Vltor SPR build. It's a complete upper (DTI 1/9 HBAR 20" 5.56 barrel, A2 F marked FSB and A2 flash hider), with charging handle, an ARMS #40 rear sight, the matching bolt carrier and bolt assemblies, and a set of the black A2 handguards. Has minor handling wear, but otherwise fine. About 2-3k rounds of factory .223 and 5.56 though it, nothing corrosive or weird.

Asking $300, including normal ground shipping. If you want it faster, let me know and I'll bump up the price to match the shipping you want. Item is located in California.
