LaserCutZ can laser engrave name, message, logo, or serial number on any metal parts this includes AR-15 receiver that is shown in this post.  Part is black anodized aluminum, we used fiber laser to color change black anodized layer to white (grey) to make the name of the owner visible. Fiber laser marking is permanent and will not be removed or get damaged by oil, chemicals, sun UV or scratches, this is ideal marking method for military needs.  Note: We will not engrave any operable or assembled weapons, we can only engrave on parts that are brought as part and not assembly. We do not allow any weapons or items that looks like weapons in our shop.
