Not gun related but this is how stuff gets engraved. Cool technology! Epilog was at Shot Show to show off their newest computer-controlled CO2 and Fiber lasers for engraving wood, metal, glass, and a host of other materials. Whether you want to burn a picture into a piece of wood or engrave your logo onto a chachki, these can probably do it. Capable of incredible accuracy and clarity, these machines are pretty cool to watch!
