Delta Team Tactical has MMC Armory complete upper receivers on sale for $53.99. I have not run any of these but the price is good.
If those dont suit you a pretty good price on Aero M4E1 complete uppers for $89.99. These are forged but have a billet look,
I havent ordered anything recently but DTT supposedly has revamped their inventory and shipping procedures. Hopefully they have resolved past issues and can get your purchases out quickly and accurately.
