Hawkeye is the premier brand in diagnostic kits for shooters so using the Hawkeye Shot Edition Slim Borescope Kit with Angled Eyepiece when purchasing used guns or analyzing mechanical problems can save you the original cost of the borescope many times over. This Shot Edition Kit features an angled eyepiece that clamps on to the borescope eyecup and reflects the image 90-degrees through its own focusing eyepiece. The angled eyepiece inverts the image, correcting the inversion of a mirror tube so it is ideal for viewing lands and grooves in a rifle with a high comb. This unique angled eyepiece allows you to quickly find erosion, fouling and tool marks that effect shooting accuracy.
