Bare aluminum 80% lower receivers have a choice of engraving endmills to be used pending what type of final finish. We recommend a 0.020″ ball endmill at a cut depth of 0.005″ for final finish of anodization. We recommend a 0.030″ ball endmill at a cut depth of 0.010″ for a final finish of paint products. Engraved bare aluminum leaves a slight edge ridge which can normally be removed with a fingernail or fine scotchbrite prior to final finish.
The part to be engraved is placed in a specialized jig and then laser probed to attain 0.0005″ level plane in the area to be engraved. This process eliminates fading which maintains a uniform appearance.
Unless otherwise noted, artwork engraving can be placed on either side magwell, or both sides. Text can be placed on just about any flat surface on the part and at any angle. Text added above or below artwork may decrease the size of the artwork pending which artwork selected and number of lines of text. There is a limitation on how many characters per text line pending selected location of text.
