https://imgur.com/a/l4Ay4cgThe black charging handle (7075) keyhole upper is from B King. Charging handle is separate for another project but included for contrast.
The gray (PSA/HRA) charging handle/Alcoa upper is a USGI contract CAPCO.
Natural sunlight, no edits.
Should give you a good idea of ano color.
The King’s upper is a P/W C/L fixed A2 M4 with extended A2, nice clean P/W job.

Their A2 stock body and buttplate appear good quality, although the swivel is somewhat shiny black (Taiwan oxide, guessing)
Handguards are clearly commercial but I have some fat Colt takeoffs snd some hi temp ceramic paint to cover the pin.
Overall I am pleased; upper came with a check/build sheet and a stapled bag with 2 MEN cases from test fire.
