I am looking to have a basic AR15 stripped upper, lower, and 13" key mod rail coated in a single color. So far the only places I know that do Cerakoate are Harsh, OK Guns & Gold, and Black Label Armament. I'm just looking to see if y'all have had good experiences with any other companies so I can shop around a bit more. The last thread I found that covered this in depth was in 2014 so I don't know if other options have emerged. A few that say they do Cerakoate just farm the work out to Harsh I believe. Any input is greatly appreciated.
