Commonly Used Phrases and Terms
LASER SIGHTS BARSKA’s Laser Sighting Systems are powered by three LR-44 Lithium batteries (included) and produce a bright dot for extreme sighting accuracy. Some models are equipped with inserts that are shaped to fit virtually all trigger guards. All models are equipped with an On-Off button and laser sights are made of tough lightweight Aluminum.
Green Laser vs. Red Laser Green is closer to the center of the visible spectrum, at 532 nanometers, so it’s easier for our eyes to perceive the color vs. a red laser at 635 nanometers. A green laser can appear as much as 50 times brighter than the red equivalent. 532nm is the ideal wavelength to maximize visibility during day or night, which makes green lasers much more visible than red lasers.
BORESIGHTERS Boresighter fits snugly in the rifle barrel to eliminate any “play” that can result in an inaccurate boresighting adjustment and poor shooting accuracy
