  • Black Oxide Treatment for M40A1

    Who does the black oxide finish for your M40A1 builds? I've been searching the internet to see who offers this service but haven't come up with anything yet.

    http://gunblack.com I used them about 10yrs ago. they did a real nice job for me.. suggest you call them, ask questions, make sure you check them out for what you want. also you can ask Mark from Raven Rifles who he uses. excellent quality there. good luck.. Andy

      I use By-Design Black Oxide and Tool, LLC in Hickory N.C. They are the best in my opinion and they will ship so you don't have to be near by. Rates are fair, however you do have to do all the prep work. If you have any questions PM me.
