I had 3 stainless rifles done in burnt bronze cerakote by Black Box Customs. I am beyond pleased with the result. They were able to do the stainless BLR apart and back together with the correct timing. They were also in constant communication so I knew where they were at in the project. It took a little longer than planned due to them having to redo the BLR as the new finish got a scratch during reassembly and had to be recoated, something that they communicated to me without prompting. They told me nothing leaves the shop unless it's 100% perfect, which I definitely believe.
