I think it's got character just the way it is. You could wrap the handguards and stock so that it wasn't such a stark contrast between the guts and the grips.
You could also get it cerakote'd/refinished. Here's a few threads I found on Arfcom about matching the O.G. Colt finish on retro rifles.
Seems that Norrell's Grayish-Black Flat moly resin is the best match.
Not meaning to double-tap, but couldn't get this last link to work in my O.G. post. Anyway, here's the site.
The color you'd need even has "COLT" in the name.
maybe with nano technologies it is possible

I would totally Ceracote that puppy
As I retro collector I avoid Cerakote. I tried a bunch of combos but it just just doesn't look correct on retro ARs. I personally use Norrell's Moly Resin as someone noted above.
Not sure if the camera is picking up the differences but here are two examples.
For early stuff like this Colt 601 I used flat gray.
For this M16A1 I used grayish-black, it has a factory Colt upper, but it is one of the darkest factory uppers I own. If you want it a little darker you can mix a little matte black with grayish-black.
It goes on super light with an airbrush you can pickup at any hobby shop. The heat cured version will need to go in the oven.
Looking forward to the finished pictures.
