LMAO that’s funny.Just a general FYI...Out of curiosity I contacted 17 Design to see if there was a good way to remove the white color fill in on their receivers. Their response...Use a Sharpie. [emoji1]
I am wanting to do the same with a Spikes Tactical lower that I have. I saw a YouTube video of a guy using acetone or fingernail polish remover and a brush. He said that the acetone will peel up the color fill without impacting the anodizing. I have not taken the time to do this, you may want to verify before you try but it looks very easy and painless to do.
