Hawkeye Borescopes are used by an increasing number of shooters to check their barrels for erosion and fouling problems. The Hawkeye Borescopes have been recently upgraded with even better optics and improved mirror technology to provide a sharper, clearer picture of the rifle bore. The Shooter's Edition - kit includes a 17 inch borescope with a focusing eyepiece for viewing straight down the bore, a mirror adapter for looking 90 degrees into the side wall of the barrel, a light source, hard storage case. Angled eyepiece is also available separately for those who already have a Hawkeye Borescope. This model will work on 22 caliber and larger.
