The .22 LR premium laser for shooting in the barrel is a high-quality device that facilitates setting the optical sight or collimator almost without firing shots. The body of the indicator is made entirely of brass, which ensures its durability and prevents the barrel from being scratched. Contrary to cheaper devices of this type, the premium laser pointer is characterized by high quality (brass) and perfect focus of the laser beam, thanks to which we have a guarantee of precise sight setting. The indicator, after inserting it into the cartridge chamber, emits a precise laser beam (wavelength 650 nm), which we see at the target. This enables the basic setting of the scope and collimator without the need to fire shots or limiting their number to just a few, which saves our time and money. When shooting at long distances, you should remember about the ballistics of the projectile, so after the initial calibration with the indicator, you should always fire a control shot to confirm that the settings are correct. Premium laser pointers are dedicated to all the most important calibers of hunting and sports weapons. Recommended shooting distance up to 25-30 m.
