Looks good! Is the surface finish raw or did you clear coat it? The reason I ask is carbon fiber and glass reinforced filaments tend to have exposed fibers that will embed in your skin when handling the raw material. If your cheek feels itchy after a shooting season, it will be from these exposed fibers breaking off into your skin. Applying a clear coat to the top surface should encapsulate the fibers and stop this. If you want the matte finish without the fibre re-enforcement, I know of a matte black Petg filament that is produced by California filaments that might be the ticket. I have not personally used their matte Petg products, but have had great results with their regular Petg products. You might be able to achieve a satisfactory matte finish with regular black Petg by upping to max volumetric flow rate on your printer. Conduct a max volumetric flow rate test and determine at which rate the surface finish goes from shiny to matte. This will be at the cost of the overall strength of the final product though.
