The Story
The Optical Bore Alignment Kit by Barska uses a 15-piece precision expanding adapter set that ranges from 4.5mm to 12.7mm internal diameter points and ensures precise component placement right from the start. These calibration guides fit snugly inside the machinery sleeve or cylinder barrel to eliminate any "play" that can result in an inaccurate alignment adjustment and poor operational accuracy. Backed by Barska's 1 year limited warranty.
