My 16 year old son recently died. Before he died he made an excellent AR 15 from reciever up. Besides joining the Marines one of his life goals was to becomae a gunsmith and make custom arms ala Kimber, Wilson Combat etc. Since he is dead he will never get to see it but I would like to give him his company I would like to have an emblem engraved into the guns he had already built. I would like to add his "company logo" onto these guns. Where would I go to get such engraving? I live in North Oklahoma City but I would be willing to travel to have this done.
