16in epc-9 enhanced upper - Aero Precision EPC-9 16in 9mm Enhanced Complete Upper Receiver with Flash Hider

This is a great looking and great feeling upper. The enhanced feature is well worth the upcharge, with the handguard being attached to the upper receiver itself rather a barrel nut in traditional uppers makes this super rigid. While it limits you to Aero (or Ballistic Advantage or Stag...they are all related) handguards, they are nice, so it isn't a problem. The handguard itself feels great. The machining and finishing on the receiver, handguard and barrel are all fantastic. Mates perfectly to the EPC-9 lower (almost as if they were made for each other!). If I had to nit-pick...and it is just that, the birdcage flash hider seems like something better could be included like a blast forwarding device or something, but that is just being super nit-picky, and really I don't mind it either way. You can't go wrong with the EPC-9 from Aero Precision for you PCC build!
