Having a hard time finding a quality forged upper receiver assembly. Just upper, forward assist, and dust cover. Must be M4. My go to is BCM or Colt but those are unicorns right now.

Any recommendations for a quality piece that is readily available? Don't want any silly markings on them, just the typical forged stamps.

Am I SOL?

I'd Look at Aero Precision, many retailers sell them so there's a chance you'll find them in stock somewhere.

There are Colt uppers on Gunbroker right now.

Don't settle.

Not to hijack thread, but have you tried the Trition nitride BCGs they have for 99.98?

But for the OP.. I have Aero uppers and really like them.

I was planning on getting some to go with the uppers, but PSA had their NiB BCGs for sale this weekend at $109 each, how can I pass THAT up?

I would wait until you can find a colt or bcm.
Stag machines the m4 feed ramps extra small for some reason
Aero doesn't use dry film lube inside, not sure how much it matters

Specialized armament has colt uppers  instock but be prepared to over pay

Just picked up an M4 flat top receiver from Right to Bear, 55 for receiver, and if you select the upper kit with it for 15, that's 70 bucks.  I've assembled it with a faxon barrel and have test fired it, functions excellent and the ramps mate up perfect with the barrels ramps.  I like that the upper kit's ejection door was actually blackish instead of grayish.

This build is on an Aero lower. 2nd I've used. They are great so I'm sure the upper is of equal quality.

Know where I can find one?
