How To Color Fill The Engravings of Your Lower Receiver


Have you ever seen someone’s rifle with colored paint in the markings on the receiver? If you’re looking for how to get that look, here’s how you can do it yourself!

Making the pitted lettering on an AR receiver white:

Supplies Needed:

  • Pencil with normal pink-colored eraser
  • Toothpick
  • White out pen (fine point preferrable)
  • Paper towels/rag

*** DISCLAIMER: I TAKE NO RESPONSIBILITY FOR ANY FAILED MODS YOU MAKE TO YOUR GUN. THIS PROCESS WORKED FOR ME AND YOUR MILEAGE MAY VARY. DO NOT TRY THIS IF YOU DONT FEEL COMFORTABLE DOING IT!!! I SUGGEST THAT YOU TRY YOUR WHITE OUT ON THE INSIDE OF THE MAG WELL TO MAKE SURE THAT IT WILL NOT STAIN YOUR RECEIVER BEFORE APPLYING IT TO THE OUTSIDE ***

Step 1:

Wipe down your receiver to make sure there is no oil or dirt around or in the pitting/lettering.

Step 2:

Take the white out pen in one hand and a paper towel/rag in the other. Press the white out pen down and squeeze a generour amount of white out along the lettering/pitting so that it completely fills the grooves of the lettering. Only do small sections at a time, and each time you do one, wipe and smear the whiteout with the paper towel like you see in the picture. The stuff dries fast and is harder to get to come off if it is pooled or clumped. So do 1 or 2 letters at a time and quickly smear it. Then do the next few, and so on until finished with all of them.

Step 3:

Now that you have smeared all of the white out, take your pencil and erase what you can, but be sure NOT to go over the grooved areas because the white out has not fully dried. If you get eraser dust/residue in the pitting/grooves before it has dried, it will probably stick to it. So just erase the flat areas, like the picture below:

Step 4:

It has now probably been about 5 minutes or so and the white out as dried, and now that you have done all that you can with the eraser, some resigue is still apparent. Take your finger and rub the affected area as hard as you can until you see it lightly smearing it into a blur. Do this until the rubbing is no longer effective. There should still be a faint haze

Step 5:

Depending on how fast you wiped the white out from the grooves, you may have had some streaks or pools dry which will not disappear by erasing or rubbing. In this case, take a toothpick and scrape off any affected areas. You will either see it crumble off or smear somewhat, depending on how thick it is. Once that is done, go back to rubbing it out again with you finger.

Step 6:

Now to take care of that faint haze, take the eraser to the entire surface, including going over the grooves/pitting. You will see that this takes the haze away rather easily. Repeat the rubbing/erasing if necessary until all visible haze/smear is gone.

Step 7:

You should now have a clean, black surface area and only have the white out visible in the grooves lettering. Nice and clean!
