Close, but not quite.no it does not... lazer engraving just changes the surface and doesnt really "cut" into the metal. per the aft if must be at least 7 mils deep.
Close, but not quite.
ATF requirement for depth is .003" (3 mils), not 7.
Also, your reply implies that all laser engraving just changes the surface, but that isn't true. The cheap laser engravers only etch the surface and burn away finishes/coatings. There are laser engravers that will actually engrave to depth in the metal. Unfortunately I believe to get into that game with a laser is going to run you $20-40,000 on the lower end.
Not trying to single you out or pick on you, I just wanted to make sure people know the full story on laser engravers and ATF requirement for engraving.
