The universal laser tester allows you to quickly check whether your riflescope is still properly zeroed.

The laser projects the expected point of impact of the bullet. If your riflescope has been accidentally bumped, you can easily verify whether it is still correctly aligned.

Suitable for all calibers from .17 to .50.

With the Laser Tester / laser cartridge (collimator), you can check your riflescope's alignment at any time. The laser remains visible even in daylight. The tester attaches to the muzzle using the built-in magnet. Simply aim at the distance for which your riflescope was zeroed. If the projected laser point differs significantly from the reticle, the firearm should be re-zeroed.

Includes AG3 batteries.

Size: Universal, suitable for use with virtually any firearm.
