AR receiver rough external finish
I have a rifle with an upper receiver that's rough to the touch, like really fine sand paper.
It doesn't impact the function or handling, but then oiling or cleaning it's actually rough enough to pull fibers from a microfiber cloth or even a jerseycloth patch leaving the receiver covered in lint. It also sticks to foam in gun cases and is hard to pull out of a gun sock.
Short of a permanent coating like dura or Cerakote, is there any way to smooth things out a bit so this thing doesn't stick to everything fabric?

You could try a fine scotch brite pad. Grey is an ulta fine pad. Try rubbing it down with that. Obviously in a inconspicuous area first. Or recoat it all. Good time to do a custom color.
Plenty of people in the area that do cerakote including me.www.Steelvalleycasting.com is your new home for coated bullets and custom ammo.

It was made this way? If so by who? Or did someone screw with it?

Re: AR receiver rough external finish
I was thinking a mild abrasive, but was hoping there was an easy answer like "oh yeah, try Mike's miracle snakeoil!"
I'll take a look this evening, see if there's a nice inconspicuous place on the upper to try some buffing.

Look for an embossed forge logo. That could be a clue to its maker.
Suggest remove receiver from the lower, find a spot that would not show, and rub it with 0000 or maybe 000 steel wool and an oil. It may knock off the sharp tops of the grain without destroying the shade and hue. Or, doing the whole upper may yield a satisfactory finish that is smoother.

Re: AR receiver rough external finish
Going to leave it be for now.
Tried hitting it with some brass wool, and the area of the receiver is now brass colored. Steel wool, steel colored. Scotchbrite - same color as the pad (used several). Doesn't matter if I use it wet or dry. All of the spots no longer pick up lint/tear fabric, but they look pretty funny.
So for now it's kinda rough, but it's all the same color, so it'll stay that way until I decide I want to change the whole color scheme.

Toothbrush and Dawn. Or maybe Hoppe's #9. See if that will remove the discolorations and restore the original color.
There are two kinds of guns. Those I have acquired, and those I hope to.
