I have this idea of sandblasting and then anodizing the controls of an M4 (fire selector, trigger, pins) to a colour ie blue or gold.
I think it would look pretty damn sick. Like a professional level R/C car except on your gun.
Found this place right in markham

Going to find out more about cost and whether theyd even do such a small order.
opinions?
